Office Lock Replacement vs Rekey: Decision Guide
This is one of the most common questions we get from DFW business owners, and the right answer depends on several factors. Here's a clear framework: Choose rekeying when: the existing hardware is in good condition (smooth operation, no corrosion), the lock grade meets your security needs (Grade 1 or 2 for exterior doors), you're satisfied with the lock style and function, and you only need to change key access (employee departure, security concern). Cost: $35-65 per lock, completed in 10-15 minutes per lock. Choose replacement when: locks are Grade 3 and you need better security for a commercial environment, hardware is visibly worn, damaged, or corroded, you want to upgrade to electronic or smart locks, the lock style doesn't match your office renovation, you're adding new doors, or current locks don't meet ADA or fire code requirements. Cost: $120-300 per lock depending on hardware selected.

Commercial Lock Grade Requirements for Dallas Offices
Understanding ANSI/BHMA lock grades helps make the right replacement decision: Grade 1 — highest commercial grade. Required for main entry doors, high-traffic areas, and any door where security is critical. Rated for 800,000 cycles (decades of commercial use). This is what we recommend for all exterior commercial doors and high-security interior doors. Grade 2 — suitable for interior commercial doors, light-duty exterior applications, and doors with moderate traffic. Rated for 400,000 cycles. Acceptable for interior office doors, conference rooms, and storage closets. Grade 3 — residential grade. Not appropriate for commercial exterior doors. If your Dallas office has Grade 3 hardware on exterior doors, replacement (not rekeying) is the correct choice for both security and insurance compliance. Many commercial property insurance policies require Grade 1 or 2 hardware on exterior doors — upgrading can reduce your premiums.
When Rekeying Makes More Sense Than Replacing
Despite the appeal of new hardware, rekeying is often the smarter choice for Dallas offices: Budget-conscious scenarios — rekeying 20 office doors costs $700-1,300 vs $2,400-6,000 for replacement. If the existing hardware is functional and meets grade requirements, rekeying saves 60-80%. Minimal disruption — rekeying takes 10-15 minutes per lock with no door modification. Replacement may require drilling, adjusting frames, or running new wiring for electronic locks. Master key system compatibility — if you have an existing master key system, rekeying individual locks maintains the system hierarchy. Replacing with different brands may require rebuilding the entire system. Lease considerations — many commercial leases require tenants to restore original hardware upon move-out. Rekeying is reversible; replacement is not. Our recommendation: if your existing locks are Grade 1 or 2, less than 15 years old, and in good working condition, rekeying is almost always the better financial decision.
Office Lock Decision FAQ
How long does commercial rekeying take?
Rekeying takes 10-15 minutes per lock. A typical office with 10-15 locks can be completely rekeyed in a half-day. We schedule most office rekeying during off-hours to avoid disrupting business operations.
Can you rekey different lock brands to the same key?
In many cases, yes. Schlage, Kwikset, and many commercial brands can be cross-keyed. However, for the best security, we recommend using a single brand across your office suite.
Should I upgrade to electronic locks during replacement?
If you're already replacing hardware, the incremental cost to go electronic is often justified. Electronic locks add $100-200 over mechanical equivalents but eliminate future rekeying costs entirely.
