Commercial Lock Rekeying

Rekeying changes the internal pin configuration of a lock cylinder so that old keys no longer work and a new key becomes the only one that fits. The lock body, the door hardware, and the frame all stay exactly in place — only the tumblers inside the cylinder are replaced. For a mortise lock, which is the heavy-duty, rectangular lock unit recessed into the edge of many commercial doors, this process requires a trained hand because the cylinder must be extracted and repinned without disturbing the lock's complex body mechanism. Our technicians carry the pin kits and specialty tools to handle mortise lock rekeying on the spot, so you are not waiting for parts to be ordered or a second visit to be scheduled.

The result is complete key control: every copy of the old key — whether it was handed out to a former employee, left behind by a previous tenant, or simply lost somewhere in the city — becomes useless the moment our technician finishes the rekey. This is fundamentally different from simply changing door knob locks or deadbolts, which involves swapping out the entire hardware set. A commercial lock rekey is surgical, faster, and preserves the investment you already made in quality hardware.

Staff turnover is the most common trigger. Tustin's mix of retail corridors, tech-adjacent office parks near the old Tustin Marine Corps Air Station redevelopment, and service businesses means that employee rosters shift regularly. Any time a key-holding employee leaves — whether on good terms or not — the safest assumption is that the key could be duplicated or shared. Rekeying immediately after offboarding eliminates that variable entirely. The same logic applies when a property changes tenants, when a manager loses a master key, or when you discover that keys were copied without authorization.

Security concerns beyond personnel changes also warrant a commercial lock change assessment. A break-in attempt, a vandalized door, a lock that shows signs of tampering, or simply the realization that your current key system has no accountability trail are all legitimate reasons to call a professional. Our team also responds to urgent situations — if you arrive at your Tustin business and something about your entrance looks wrong, do not force the door or assume everything is fine. Call 657-571-2329 and our emergency commercial locksmith team will assess the situation, secure the entry, and rekey or replace hardware as needed, any hour of the day or night.

The range of hardware we work with across Tustin commercial properties is broad. Mortise locks are common on older commercial buildings throughout the Old Town Tustin district and in multi-suite office complexes, and they require a specific skill set that separates a trained commercial locksmith from a generalist. We rekey, service, and when necessary replace mortise lock cylinders on site. Beyond mortise hardware, our commercial locksmith services cover cylindrical deadbolts, door knob locks, lever-handle sets, rim locks, padlocks, and keypad-access locks that use a physical keyed override.

We also provide commercial lock installation when rekeying is not the right answer — for example, when existing hardware is worn, damaged, or no longer meets the security grade appropriate for the door type. A full commercial lock installation service includes helping you select the right hardware grade (ANSI Grade 1 for high-traffic or high-security applications is our standard recommendation), installing it correctly so the latch and strike plate are properly aligned, and cutting new keys on the spot. If your business needs a master key system — one key that opens multiple locks, with individual keys for each suite or department — we design and implement that as well, using quality hardware from brands like Schlage to ensure long-term reliability.

Pricing for commercial lock rekeying depends on several factors: the type and brand of lock (a mortise lock cylinder takes more time and specialized pins than a standard cylindrical lock), the number of locks being serviced, the time of day (after-hours and overnight calls reflect the cost of 24/7 availability), and travel distance to your location within the Tustin service area. Before any work begins, your technician will give you an exact, confirmed price — not an estimate that grows once the job is underway. There are no surprise charges added after the fact.

Because we are fully mobile, we come to your business address equipped with the tools, pin kits, and key-cutting equipment to complete most commercial lock rekeying jobs in a single visit. You do not need to remove hardware and bring it anywhere. Our technicians work damage-free wherever possible, meaning we use proper extraction tools rather than force — protecting your door frames, finish hardware, and the surrounding surface. For businesses in active operation, we coordinate with you to minimize any window during which a door must be held out of service, and in most cases that window is very short. To get a clear, upfront quote and schedule your service, call 657-571-2329 — we answer 24/7.
