Should I rekey or replace my commercial locks?

If the locks are in good working condition and you just need to invalidate old keys, rekeying is more convenient and practical. If the locks are worn, outdated, or you want to upgrade security, full replacement is the better investment. We'll assess and recommend honestly.

How long does a full commercial lock change take?

It depends on the number of doors. A typical small office (5-10 doors) takes 2-4 hours. A larger building may take a full day. We can provide an accurate time estimate after the initial assessment.

Can you change locks for a multi-tenant building?

Absolutely. We handle multi-tenant buildings regularly — setting up unique keys for each tenant while maintaining master key access for building management. We coordinate with property managers for smooth tenant transitions.

What's the difference between Grade 1 and Grade 2 commercial locks?

Grade 1 is the highest commercial rating — built for heavy daily traffic and maximum attack resistance. Grade 2 is designed for lighter commercial use like interior offices. Both are significantly stronger than residential Grade 3 hardware. We'll recommend the appropriate grade based on each door's traffic and security needs.

Can you set up locks so different employees have different access levels?

Yes. We design master key systems where management keys open all doors while employee keys only open their designated areas. Combined with restricted keyways, this gives you layered access control without the cost of electronic systems.

Problems We Solve

Signs You Need a Lock Change

Employee Left with Keys

They turned in their badge but kept copies of the keys. Or they 'lost' them weeks ago. Rekeying makes every old key useless — instantly and affordably.

Lease Turnover — Who Has Keys?

The previous tenant, their employees, contractors, cleaning crews — you have no idea how many key copies exist. A full lock change gives you a clean slate.

warning

Locks Are Old and Unreliable

Sticky deadbolts, loose knobs, and locks that need wiggling to work are a daily headache — and a security liability. Upgrading to modern commercial-grade hardware solves both problems.

Security Breach or Break-In Attempt

If someone tampered with your locks, forced a door, or attempted unauthorized access, every lock they may have compromised needs immediate replacement — not just the damaged one.

Non-Compliant Hardware on Accessible Entrances

Round doorknobs on public-facing entrances violate ADA requirements. If your building has been flagged or you're renovating, we install compliant lever handles that meet accessibility standards.
