Rekeying Locks vs. Rekeyable Locks: Which is better for your facility?

Here’s an alarming statistic: According to a report published in late 2025, 42,508 reported burglaries took place in commercial or office buildings in the United States, while 23,358 reported burglaries took place in restaurants in that same year; which means your facility’s key system isn’t just a convenience—it’s a critical layer of protection. For facility managers, retail security teams, and campus administrators, the choice between traditional rekeying locks and modern rekeyable locks affects costs, downtime, and overall security. This guide clarifies the differences so you can confidently choose the best approach for your organization.

What Does Rekeying Locks Mean?

Rekeying locks means adjusting the lock’s internal pins or wafers so a new key operates the lock while the existing hardware stays in place. In commercial environments, this process usually requires removing the lock core, manually changing pin combinations, and issuing new keys. It’s used when keys are lost or stolen, staff turnover occurs, or unauthorized access needs to be prevented. While effective, the process often requires locksmith services, creates downtime, and becomes more costly when applied across multiple doors or locations.

What Are Rekeyable Locks?

Rekeyable locks are designed so you can change the lock’s pin combination without removing hardware or calling a locksmith. With a specialized step-change key, authorized personnel can disable the old key and activate the new one in a matter of seconds. The process involves inserting the step-change key, performing a controlled turn inside the lock, and setting the new key as the active credential. Because hardware stays in place and labor is not outsourced and can be managed by staff. Rekeyable locks deliver cost efficiency and immediate responsiveness at scale.

Rekeying Locks vs Rekeyable Locks: Key Differences

Hardware Changes: Rekeying locks often require replacing lock cores or full hardware, while rekeyable locks allow combination changes without removing or replacing any components.
Labor Costs: Rekeying locks typically involve higher labor because a locksmith is required for most changes. Rekeyable locks keep labor low by enabling user-driven rekeying.
Time Required: Traditional rekeying takes longer due to coordination, service calls, and potential downtime. Rekeyable locks support immediate rekeying on the spot.
Scalability: Rekeying becomes difficult and expensive as door or site counts increase. Rekeyable systems scale easily across multi-site operations.
Response to Lost Keys: Rekeying locks provide effective protection but rely on service scheduling. Rekeyable locks disable old keys instantly.
Upfront Cost: Rekeying locks cost less initially, but rekeyable systems reduce lifecycle costs by eliminating ongoing service and hardware replacements.

Why Rekeyable Locks Are Often the Better Choice

When a key is lost or compromised, response time matters. Rekeyable locks eliminate delays by allowing authorized employees to change the lock instantly. This reduces both risk and cost—especially in organizations with many doors or high staff turnover. Rekeyable systems also support restricted keyways and built-in key tracking, improving overall key-control practices. When evaluated over time, the reduced service calls, shorter downtime, and increased security typically outweigh the higher initial investment.

When Rekeying Still Makes Sense

Traditional rekeying may still be practical for facilities with a small number of locks, low turnover, or upcoming major hardware upgrades. If rekeying events are rare and locksmith access is simple and affordable, the traditional approach can meet operational needs. However, long-term costs and response times should still be factored into your decision.

Decision Checklist: Which Solution Fits Your Facility Security Needs?

• Number of doors and sites you manage
• Frequency of lost or compromised keys
• Budget for hardware vs ongoing service
• Whether key control is centralized or distributed
• How quickly you need to respond to security risks

If rapid response, cost predictability, and operational control are priorities, rekeyable locks are the stronger choice.

Implementation Tips for Rekeyable Locks

1. Choose a system that supports user-driven rekeying.

2. Use restricted keyways to prevent unauthorized duplication.

3. Establish standardized key-control policies across teams.

4. Train authorized personnel on the rekeying process.

5. Periodically review usage, rekeying frequency, and operational ROI.
