When we arrive, we start by looking at the locks you want changed and asking which keys should still work when we're done. For a commercial rekey, that means we adjust the lock cylinders so old keys stop opening the door and the new keys do. If you've had staff turnover, a missing master key, or a key that's been copied more than it should've been, rekeying gives you control again without replacing every lock in the building. We do the work where the locks are, whether that's an office in Glen Mills, a warehouse, a medical suite, or a retail space with several entry points.
We remove each cylinder, change the pin setup inside, and test the new key against every lock we touched before we leave. If your building uses different keyways, keyed-alike doors, or a master key system, we can keep the setup organized so the right doors open with the right keys and the wrong ones don't. If a lock is worn, damaged, or not worth rekeying, we'll tell you that plainly and talk through the next step. The goal is to secure the property without creating more work for your staff or shutting down the day's business.
Commercial rekeying makes sense when you need to protect access after a key has gone missing, an employee leaves, or a tenant changes. It's also a practical move when you want to tighten up who can get into an office, stock room, file area, or side entrance. Because we're mobile, our van carries the tools and parts needed to handle the job on site across Delaware County, Chester County, and New Castle County. We keep the process straightforward: assess the locks, rekey what should stay, flag what needs attention, and get the building back under your control.
