You’re managing a Houston business. An employee just quit. Another was terminated last week. Your office manager retired after 20 years. And you’re standing there wondering: do I need to rekey the locks? Replace them? Do anything at all?
Or maybe you just signed a lease on a new commercial space. The previous tenant moved out months ago. The landlord assures you “the locks were changed.” But you’re looking at standard keys that could have been copied dozens of times during the previous tenancy.
Here’s what most business owners don’t realize: the decision to rekey or replace locks isn’t just about security—though that’s critical. It’s also about liability, insurance requirements, employee safety, compliance, and protecting business assets worth tens or hundreds of thousands of dollars.
Make the wrong call, and you’re exposed to theft, liability claims, or insurance denials. Make the right call at the wrong time, and you’re wasting money on unnecessary lock changes.
This guide breaks down exactly when Houston businesses should rekey or replace locks, the difference between rekeying and replacement, mandatory situations requiring immediate action, optional scenarios where it might be wise, and how to make cost-effective decisions that protect your business without breaking the budget.
Understanding Rekeying vs. Lock Replacement
Before deciding whether to act, understand what each option actually means.
What Is Rekeying?
Rekeying changes the lock’s internal pins so old keys no longer work. The locksmith removes the lock cylinder from your door, disassembles it, and removes the current pin configuration. They then replace those pins with a different arrangement, reassemble the cylinder with the new pin setup, and issue new keys that match the new configuration. Your old keys no longer operate the lock.
What stays the same is the actual lock hardware—the handle, deadbolt, and all visible components remain unchanged. The lock’s appearance and functionality stay identical. Your door hardware and installation aren’t touched. The security level of your existing lock remains the same.
What changes is only the internal pin configuration, which keys open the lock, and who has access to your building. Rekeying typically costs $20-$50 per lock cylinder for commercial locks and can be completed quickly—a professional locksmith can rekey multiple locks in hours, not days.
What Is Lock Replacement?
Lock replacement removes old hardware completely and installs entirely new locks. The locksmith removes your existing lock from the door, installs new lock hardware, ensures proper fit and function, and provides new keys for the new locks.
Everything changes with replacement: the entire lock mechanism and hardware, the security level if you’re upgrading to better locks, the appearance and style of hardware, and the key type and keyway. Lock replacement becomes necessary when locks are damaged, worn, or malfunctioning, when you’re upgrading to higher security locks, when locks are outdated or obsolete, when changing to a different lock type like keypad entry, or when the lock cannot be rekeyed because some cheap locks don’t have rekeyable cylinders.
Replacement typically costs $100-$400 per lock depending on quality and type, and takes more time than rekeying since you’re installing entirely new hardware.
Which Option Is Right for Your Business?
Choose rekeying when your locks are functional and in good condition, when the current security level is adequate, when you just need to invalidate old keys, when cost is a concern, or when you need quick turnaround. Most businesses find that rekeying existing functional locks is sufficient and cost-effective for routine employee turnover and access control.
Choose replacement when locks are damaged or worn, when upgrading security is a priority, when locks are low-quality and not worth rekeying, when moving to keyless or electronic access systems, or when locks cannot be rekeyed at all.
Mandatory Situations: When You MUST Rekey or Replace Locks
Certain situations require immediate lock changes for security and liability reasons.
Employee Terminations (Especially Involuntary)
When an employee is fired or let go involuntarily, you face immediate security risks. The terminated employee may have copies of keys you don’t know about, creating ongoing access to your building after termination—a serious liability issue. Disgruntled former employees pose real security threats, and keys may have been copied without your permission during their employment. Master keys or access codes may also be compromised.
Best practice is to rekey locks immediately—ideally the same day the employee is terminated. Change access codes on keypad entries, deactivate any key cards or fobs, update security system codes, and document the rekeying for insurance purposes. This prevents unauthorized access by the terminated employee, protects against theft or sabotage, demonstrates reasonable security measures for insurance claims, and reduces your liability if an incident occurs.
A Houston retail business learned this lesson the hard way. They didn’t rekey after firing their manager. The former employee returned after hours and stole $15,000 in merchandise. Their insurance company denied the claim because the business failed to take “reasonable security measures” by not rekeying the locks.
Lost or Stolen Keys
When keys go missing, you need to assess the security compromise quickly. Common scenarios include an employee losing keys with no idea where they went, keys stolen during a burglary or robbery, keys left in a vehicle that was later stolen, a purse or bag stolen with keys inside, or keys missing when the building address is identifiable on the key ring or attached items.
Your risk assessment should consider several questions: Are the keys labeled with your business address? How many keys were on the ring? Were master keys included? How long have the keys been missing? Have there been any signs of attempted break-in since the loss?
Immediate action requires rekeying all locks those keys opened, ideally the same day. Change alarm codes, alert your security service if applicable, increase monitoring for suspicious activity, and document the loss and rekeying for insurance purposes.
You can occasionally wait to rekey if keys were lost in a secure location inside your building, if you’re absolutely certain keys weren’t compromised, if there’s no building address on the keys, or if there are no signs of attempted unauthorized access. However, when in doubt, rekey. The cost of rekeying a small business—typically $200-$500—is trivial compared to the potential theft or liability exposure.
Break-Ins or Attempted Break-Ins
After any security breach, immediate rekeying becomes critical. Whether a break-in was successful or not, whether you see attempted break-in with lock damage, evidence of lock tampering, or even a break-in at a neighboring business where keys may have been the target—rekey immediately.
Why immediate action matters: burglars may have obtained your keys during the break-in, lock integrity may be compromised even if nothing was stolen, insurance may require rekeying as a condition of your claim, documenting the rekeying demonstrates due diligence for future coverage, and it prevents repeat incidents.
For insurance considerations, document rekeying costs for your claim. Many policies explicitly require rekeying after a breach. Failure to rekey may jeopardize future claims, so get written confirmation from your locksmith for your records.
Lock replacement becomes necessary in different scenarios: when locks are damaged during the break-in attempt, when locks were picked or bumped showing their vulnerability, when you’re upgrading security after an incident, or when installing high-security locks to prevent recurrence.
New Business Location or Lease
Never trust that locks have been properly changed when you move into a new commercial space. The unknown key exposure is substantial: the previous tenant may have made copies, building maintenance likely has keys, contractors had access during renovations, real estate agents had keys while showing the property, and an unknown number of people may have access.
Even when your landlord claims “locks were changed,” that statement means nothing for your security. It may mean they rekeyed once when the previous tenant left, but that previous tenant may have made copies before returning their keys. There’s no verification of who has copies, and the liability is yours, not your landlord’s.
Standard practice for any new commercial lease requires rekeying all exterior door locks immediately—before you move in any inventory or equipment. Rekey interior office locks, change all access codes for alarm systems and keypad entries, document the rekeying date and locksmith company, and keep these records for insurance purposes.
From a cost perspective, rekeying all locks typically costs $300-$800 for a typical small business. Compare that to the value of inventory, equipment, and data at risk—often $50,000 to $500,000 or more. The cost-benefit analysis is obvious. Do the rekeying on day one of lease possession, not after you’ve moved in all your valuable equipment and inventory.
Master Key Compromise
When master key systems are compromised, you face a complete system vulnerability. Master key systems use one master key that opens all locks in the building, while individual keys open only specific doors. This setup is common in office buildings and multi-tenant spaces because it’s convenient, but it creates a significant security vulnerability when the master is compromised.
Master key compromise scenarios include the master key being lost or stolen, an employee with master key access being terminated, the master key being copied without authorization, or a contractor having master key access during a project.
The required action is substantial: the entire master key system must be rekeyed. You cannot rekey just one lock because that defeats the master system’s functionality. All locks in the system must be rekeyed together, and you must issue a new master key along with all new individual keys.
The cost consideration is significant—rekeying 10-20 locks in a master system typically runs $400-$1,000, which is more expensive than rekeying individual locks. However, it’s still dramatically cheaper than replacing all the locks, and it’s essential for maintaining security.
Prevention strategies include strictly controlling master key access, limiting who receives master keys, tracking all master key holders, marking master keys clearly so they’re identifiable, and never giving contractors master keys under any circumstances.
Highly Recommended Situations: When You Should Seriously Consider Rekeying
These situations don’t always require immediate rekeying, but smart business owners do it anyway.
Employee Resignations (Even Amicable)
Even when employees leave on good terms, rekeying protects your business. The risk factors are real: the employee may have made copies of keys during employment, keys may have been borrowed by family members or friends, the employee might be moving to a competitor, relationships can sour after departure, and the keys the employee “returned” may not include all copies they made.
A good employee relationship doesn’t guarantee security. People’s circumstances change—financial desperation can strike anyone. Relationships can deteriorate post-departure for reasons you never anticipated. Keys might be left with the former employee’s contacts who you don’t know. Years later, someone could have unintended access to your building.
Business best practice suggests rekeying after any employee with keys leaves, especially employees with master keys, especially employees with access to money, inventory, or sensitive data. Document this as standard operating procedure—it makes insurance claims easier if something does happen.
Consider the cost versus risk calculation. Rekeying typically costs $100-$400 for a typical small business. Theft or liability exposure from a former employee having keys? That’s unlimited. Peace of mind knowing only current employees have building access? That’s priceless.
You might skip rekeying in limited circumstances: very short-term employees who worked only 1-2 weeks, employees who never actually used their keys, employees who had office-only keys but not exterior access, or businesses with layered security including alarm systems and cameras that would detect any unauthorized entry.
The recommended schedule is to rekey within one week of employee departure, before hiring the next employee for that position, and include rekeying in your employee offboarding checklist as a standard step.
Seasonal or Temporary Workers
Seasonal and temporary workers present special considerations for access control. Common risk scenarios include seasonal staff with keys during busy periods like retail holiday rushes, temporary contractors with building access for specific projects, holiday season temporary help, summer interns or seasonal employees, or event staff with temporary access for specific functions.
Best practices include never giving temporary workers master keys under any circumstances. Issue separate keys that can be easily and cheaply rekeyed. Set calendar reminders to rekey after the season ends. Alternatively, use electronic locks with temporary access codes that automatically expire. Document who received keys and when they were issued.
The electronic solution often works best for temporary access: keypad entry with temporary codes, key card systems with time-based access that automatically deactivates, or smart locks with temporary digital keys. These eliminate the need for physical key control and the subsequent rekeying.
A cost-effective approach uses cheap locks specifically for temporary access areas. You can rekey these inexpensive locks or replace them entirely without much expense. Keep your main security using better quality locks. Limit temporary worker access to only the areas they actually need.
Change in Business Ownership
Ownership transitions require complete rekeying without exception. During a business sale or transfer, the previous owner had unlimited opportunities to make key copies. The previous owner’s employees and family members had keys. Contractors and vendors working with the previous owner had keys. An unknown number of copies are in circulation.
Partnership dissolutions create similar concerns. A former partner may retain keys even if the split was amicable initially. The partner’s family or employees may have keys. Contentious splits create serious security concerns. You need to protect business assets during the transition period.
Franchise changes also require rekeying. The franchisor may have had access under the previous arrangement. The previous franchisee may have made copies during their tenure. Corporate staff may have keys from the old ownership. A new franchise should start with completely fresh security.
Immediate action means rekeying all locks on the day of ownership transfer. Change all access codes and alarm codes at the same time. Update the security system credentials. Document all changes for insurance purposes. Notify your insurance company of the ownership change.
Due diligence during acquisition should make rekeying part of the purchase agreement. Budget for rekeying costs in your acquisition expenses. Complete the rekeying before taking possession of the property. Verify everything with locksmith documentation for your records.
After Contractors or Vendors Have Access
Temporary contractor access creates ongoing risk even after the project is complete. Common contractor scenarios include renovation or construction work, HVAC, plumbing, or electrical repairs, janitorial or cleaning services, delivery or stocking services, and security system installation ironically enough.
Why contractors pose risk: keys may be copied without your knowledge during the project, multiple contractor employees may have accessed the keys, subcontractors may have received keys without your knowledge, keys may be lost or stolen from the contractor’s vehicle or office, or the contractor relationship may end badly over payment disputes or quality issues.
Best practices during contractor access include never giving contractors master keys under any circumstances. Use a separate key that can be cheaply rekeyed after the project. Require documented key return and verify it personally. Rekey promptly after project completion. Alternatively, use temporary access codes instead of physical keys.
Rekey after long-term contractor projects like major renovations, if any contractor relationship ends badly, if a contractor loses keys at any point, or if you have any security concerns whatsoever. Consider it standard practice after major work.
Preventive measures include using electronic locks with contractor-specific codes that you can easily change, issuing keys that can be easily and cheaply rekeyed separately from your main security, scheduling rekeying costs into your project budget from the beginning, and including key return requirements in contractor agreements.
Employee Promotes to Management with Master Key
Adding master key access changes your risk profile significantly. When an employee receives a master key for the first time, they now have access to the entire building instead of just their work area. They may make copies of the master key for convenience. A lost or stolen master key affects all locks in your system. If that employee is later terminated, they leave with master access.
A proactive approach means rekeying the master system when you want to restrict who has master access. Issue new master keys only to trusted management personnel. Track who has master keys very carefully. Plan to rekey the entire system when any master key holder leaves the company.
An alternative to master keys eliminates many of these problems: electronic access control with individual codes for each employee, different access levels for different employees based on their roles, audit trails showing exactly who accessed what and when, and the ability to revoke access instantly without rekeying anything.
Optional Situations: When Rekeying May Not Be Necessary
Some situations seem to require rekeying but may not actually need it.
Employee Quits with Full Notice and Good Terms
Low-risk departure scenarios exist, though they’re less common than business owners hope. An employee who gives two or more weeks notice, leaves on excellent terms, returns all keys personally, is moving to a completely non-competing field, and never had access to cash, inventory, or sensitive data presents minimal risk.
Your risk assessment should consider whether the employee could have made copies during employment—this is always possible regardless of how trustworthy they seemed. Does the employee have any financial motivation to return and steal? This seems unlikely if they’re leaving on genuinely good terms for a better opportunity. Is the relationship likely to sour after departure? While it seems unlikely during an amicable departure, circumstances can change. What assets could the employee access if they returned? If the relationship is truly solid and they had minimal access to valuable items, risk may be low.
Decision factors include weighing the cost of rekeying against the actual risk level, considering the size and type of your business, evaluating the value of assets the former employee could access, checking whether your insurance requires rekeying after any departure, and honestly assessing your own risk tolerance.
A middle ground approach lets you wait 30 days while monitoring for any suspicious activity. Rekey if anything unusual occurs. Consider rekeying when you hire a replacement for that position anyway. You can also batch multiple departures together for more economical rekeying.
However, rekey anyway if the employee had a master key regardless of the departure circumstances, if they had access to high-value items, if they worked late or alone often, if your insurance policy requires it, or simply if peace of mind is worth the cost to you.
Keys Lent to Trusted Friends or Family
Temporary key access to trusted individuals rarely requires rekeying. Scenarios include the business owner lending a key to a family member briefly, an employee letting a friend use a key for legitimate reasons, a trusted person needing temporary access for a specific purpose, or a key being borrowed and returned the same day.
This usually doesn’t require rekeying because the access was short-term and supervised, the relationship is trusted, the key was returned intact without copies likely being made, and there are no security concerns about the temporary access.
Red flags that would require rekeying include a key not being returned promptly, concerns about copies being made during the temporary access, any deterioration in the relationship, any suspicious activity following the temporary access, or uncertainty about who else may have accessed the borrowed key.
Lock Shows Normal Wear But Still Functions
Cosmetic issues don’t always require immediate replacement. A lock that looks worn but operates fine, a key that’s slightly hard to turn but still works, a lock with scratches or cosmetic damage, or a lock with outdated style but adequate security may not need immediate attention.
When wear doesn’t require replacement: if lock mechanisms function properly, if keys work reliably every time, if the lock hasn’t been compromised, if the security level is adequate for your needs, and if budget is tight, you can defer replacement.
When wear requires attention: if the lock sticks or jams frequently, if keys occasionally break in the lock, if the lock fails to engage fully when locked, if you have concerns about reliability, or if the lock could fail at a critical time, replacement becomes necessary.
A maintenance approach includes lubricating all locks annually, replacing locks when function starts deteriorating, budgeting for eventual replacement before complete failure, and not waiting until locks fail completely during business hours.
Creating a Business Lock Rekeying Policy
A systematic approach prevents security gaps and saves money long-term.
Establish Clear Triggers for Rekeying
Mandatory rekeying triggers should include any involuntary employee termination, any lost or stolen keys, any break-in or attempted break-in, any new business location or lease signing, any master key compromise, and any change in ownership structure.
Recommended rekeying triggers include any employee departure even if amicable, seasonal worker departure after their term ends, the end of extended contractor access, partnership structure changes, and annual security audits that identify vulnerabilities.
Discretionary rekeying triggers cover situations like relationship concerns with a former employee, suspicion of unauthorized key copying, general security upgrades you’re implementing, or lock wear and malfunction that’s creating security concerns.
Document All Rekeying Events
Maintain detailed records for insurance purposes—many insurers require documentation of security measures for claims. Create a security audit trail showing your due diligence. Include rekeying in employee offboarding documentation. Meet compliance requirements for certain industries. Keep tax deduction documentation for security expenses.
What to document: the exact date of each rekeying, the specific reason for rekeying, which locks were rekeyed in detail, the locksmith company used and their invoice, who authorized the rekeying decision, and who received new keys and when.
Employee Key Tracking System
Know who has keys at all times by maintaining a comprehensive log of all keys issued. Document who received each specific key, the date each key was issued, the type of key (master key, individual key, specific door access), and the date keys were returned when employees leave.
Key issuance policy should require employees to sign a key agreement upon receiving keys. Employees acknowledge responsibility for keeping keys secure. They agree to return all keys immediately upon departure. They agree never to copy keys without explicit written permission. They understand the consequences of violating the key policy.
Key return procedure requires employees to return keys personally on their last day of employment. They cannot leave keys with a coworker or in their desk. They must return all copies they made. Verify key return in writing with the employee’s signature. Schedule rekeying regardless of key return—returned keys don’t eliminate copies you don’t know about.
Annual Security Audit
Review lock security every year by asking critical assessment questions. Who currently has keys to your building? Are there employees who left where you didn’t rekey the locks? Are all locks in good working order? Is your master key system secure from compromise? Do you need to upgrade locks for better security?
Annual maintenance includes lubricating all locks to extend their lifespan, testing all keys to ensure they work properly, replacing worn locks before they fail, updating your key tracking log with current information, and considering security upgrades based on your business growth.
Budget planning requires estimating rekeying costs for the coming year based on typical employee turnover, budgeting specifically for anticipated employee departures, planning for necessary lock replacements before failure, and considering electronic lock upgrades that might reduce long-term rekeying costs.
Cost Considerations: Making Smart Financial Decisions
Balance security needs with budget realities by understanding actual costs.
Understanding Rekeying Costs in Houston
Typical commercial rekeying prices in Houston include $20-$40 per cylinder for standard commercial locks, $40-$75 per cylinder for high-security locks, $30-$60 per lock in master key systems due to complexity, $50-$100 service call fees that may cover multiple locks, and emergency or after-hours service at 1.5 to 2 times regular rates.
A small business example shows realistic costs. For two exterior doors at the front and back, expect $80-$160. Three interior office doors run $60-$120. The total for basic rekeying of a small office is $140-$280.
A larger business example shows how costs scale. Five exterior doors cost $100-$200. Fifteen interior doors run $300-$600. A master key system for the entire building costs $480-$900. The total for a larger facility is $880-$1,700.
Rekeying vs. Replacement Cost Comparison
When rekeying is dramatically cheaper, the numbers are compelling. Consider a scenario where 10 locks need securing after an employee departure.
Rekeying costs include 10 locks at $30 average each totaling $300, 1-2 hours of locksmith time, same day completion, and new keys issued to all current employees.
Replacement costs include 10 new commercial locks at $150 average each totaling $1,500, installation labor of $500-$800, 4-8 hours of work disrupting your business, and total costs of $2,000-$2,300.
The savings by choosing rekeying over replacing functional locks is $1,700 or more.
Budgeting for Lock Security
Annual security budget guidelines vary by business size. A small business with 1-10 employees should budget $500-$1,000 annually. This covers typical employee turnover rekeying, occasional lock replacement, and emergency rekeying if needed.
A medium business with 11-50 employees should budget $1,000-$3,000 annually. Higher employee turnover means more frequent rekeying. Master key system maintenance adds cost. Security upgrades periodically become necessary.
A large business with 50 or more employees needs an annual security budget of $3,000-$10,000 or more. Complex master key systems require ongoing maintenance. Electronic access control systems have initial and ongoing costs. Regular security audits identify vulnerabilities requiring attention.
Ways to reduce costs include batching multiple employee departures together for one rekeying visit, using electronic locks for temporary workers to eliminate physical key rekeying, limiting master key distribution to reduce complex system rekeying needs, maintaining locks properly to extend their lifespan, and developing an ongoing relationship with a locksmith for better rates.
Electronic Alternatives: Reducing Rekeying Needs
Modern technology offers alternatives to traditional rekeying that can save money long-term.
Keypad Entry Systems
Keypad entry systems eliminate physical key issues entirely. The advantages include changing access codes instead of rekeying locks, assigning unique codes to each employee for accountability, creating temporary codes for contractors that automatically expire, maintaining an audit trail of entry times, and instantly revoking access by simply changing the code.
Costs for commercial keypad locks range from $200-$600 per lock. Installation runs $100-$200 per lock. After initial investment, there are no rekeying costs ever—you simply change codes as needed. The only ongoing expense is occasional battery replacement.
Best applications include main entrance doors where many people need access, high-turnover businesses where employees come and go frequently, buildings with contractors who need temporary access, and after-hours access control where you need to track who enters when.
Key Card or Fob Systems
Professional access control using cards or fobs offers sophisticated security. Advantages include easily issuing and revoking access without touching locks, tracking exactly who enters and when, creating different access levels for different employees, deactivating lost cards immediately, and never needing to rekey locks.
Costs include a basic system for $1,000-$3,000, per-door hardware of $500-$1,500 per entrance, and individual cards or fobs at $5-$15 each. While initial investment is substantial, long-term cost savings versus constant rekeying can be significant.
Best applications include multi-door facilities where comprehensive access control matters, buildings with many employees requiring different access levels, high-security requirements where audit trails are necessary, and businesses needing detailed entry logs for compliance.
Smart Lock Technology
Modern electronic solutions offer cutting-edge capabilities. Features include smartphone-based access eliminating physical keys entirely, temporary digital keys you can issue and revoke remotely, remote access management from anywhere, integration with broader security systems, and detailed access logs and monitoring.
Considerations include requiring reliable internet connectivity, battery or power requirements for operation, a technology learning curve for staff, higher initial investment than traditional locks, but substantial long-term savings from eliminating all rekeying.
Smart locks make sense for businesses with frequent employee turnover, situations where contractor access is common, environments needing multiple access levels, industries with security audit requirements, and budgets allowing upfront investment for long-term savings.
Working with Professional Locksmiths
Choose the right locksmith for your commercial rekeying needs.
What to Look for in Commercial Locksmiths
Essential qualifications start with genuine experience with commercial properties. Your locksmith should understand business security needs that differ from residential, have expertise with master key systems, offer after-hours availability for emergencies, provide fast response times for urgent situations, and have commercial client references you can verify.
Services beyond basic rekeying should include lock repair and replacement, comprehensive security assessments, master key system design and maintenance, electronic lock installation and programming, and emergency lockout service when you need it most.
Business-friendly practices matter significantly. Look for flexible scheduling including after hours and weekends, invoicing and payment terms suitable for business accounts, detailed documentation for insurance claims, service agreements for regular clients needing ongoing support, and transparent pricing without hidden fees.
Questions to Ask Before Hiring
Vet commercial locksmiths carefully by asking about experience and credentials. How long has the company been in business? What commercial clients have they served? Are they properly licensed and insured? Can they provide references you can contact? Are they bonded for security work?
Assess specific capabilities by asking about experience with your particular lock types, ability to rekey master key systems, after-hours emergency service availability, same-day service options, and electronic lock capabilities if relevant.
Understand pricing and logistics by asking about service call fee structure, per-lock rekeying costs, emergency and after-hours rates, payment terms and accepted methods, and warranty coverage on their work.

Frequently Asked Questions
How much does it cost to rekey commercial locks?
Commercial rekeying typically costs $20-$50 per lock cylinder. Small businesses with 5-10 locks can expect to pay $200-$500 for complete rekeying. Master key systems cost more due to the complexity of maintaining the master key functionality across all locks.
How long does commercial rekeying take?
A professional locksmith can rekey 5-10 locks in 1-2 hours for a typical small business. Larger buildings or complex master key systems may take 3-6 hours. Most businesses can have rekeying completed in a single visit, minimizing disruption to operations.
Do I need to rekey locks after every employee leaves?
Best practice is yes, especially for employees with master keys or access to valuable assets. At minimum, rekey after all involuntary terminations and when employees with significant access leave. Even amicable departures warrant rekeying since you can never be certain all key copies were returned.
Can I rekey commercial locks myself?
This isn’t recommended for several reasons. Commercial locks are more complex than residential locks. Master key systems require specialized expertise. Mistakes create security vulnerabilities that could cost far more than professional rekeying. Professional rekeying includes warranty protection.
How often should businesses rekey locks?
Rekey whenever employees with keys leave the company, after any security incidents, annually as a preventive measure, or anytime key control is uncertain. High-turnover businesses may need quarterly rekeying. Some businesses rekey on a set schedule regardless of employee changes.
What’s the difference between rekeying and changing locks?
Rekeying changes the internal pin configuration so old keys don’t work, while keeping the same lock hardware. Changing locks (replacement) installs completely new lock hardware. Rekeying is substantially cheaper and sufficient for most situations where locks are functional but you need to invalidate old keys.
