Lock Rekeying in Markham
GTA Lockman Mobile Locksmith Services provides professional residential and commercial lock rekeying, lock cylinder recoding, and master key setups in Markham and the GTA. We update your pins, invalidating old keys without replacing expensive lock bodies.
Restoring Key Control & Upgrading Pin Arrays
Lock rekeying is a highly effective way to maintain key control without replacing your entire lockset. When moving into a new home or managing a commercial property transition, you cannot be sure who has copies of the old keys. Rather than buying new locksets, a professional locksmith can extract the existing cylinder, replace the inner brass pins with a new configuration, and cut new matching keys. This instantly renders all old keys useless.
At GTA Lockman Mobile Locksmith Services, our mobile service vans carry pin kits, shims, follower tools, and key cutters. We rekey residential deadbolts, commercial mortise cylinders, and profile cylinders in a single visit.
- Cylinder repinning for standard and high-security locks
- Master key system configuration for office doors
- Key duplication and coding for restricted cylinders

Panic Bar & Exit Devices
Safe exit egress requirements dictate that public buildings feature crash bars on exit routes. We install and service push-pad exit bars, vertical rod panic devices, and alarms. Proper adjustment ensures the door unlatches with minimal pressure during evacuation.
Hydraulic Door Closers
A leaking or slamming door closer is a hazard that can damage frames and cause injury. We replace worn hydraulic cylinders, calibrate closing speeds, and adjust backcheck cushioning. Correct regulation keeps the door closing smoothly without slamming.
Security Plates & Latch Guards
Exposed latches are vulnerable to prying, shimming, and crowbar attacks. We install heavy steel latch protectors, cylinder guards, and frame reinforcement plates. These physical barriers shield the lock latch and discourage break-in attempts.
High-Security Lock Cylinders
Upgrading to restricted key systems prevents unauthorized duplication. We install drill-resistant mortise cylinders, patent-protected keys, and high-security locks like Mul-T-Lock Interactive+ or Classic Pro. This helps ensure key control and threshold protection.
