Commercial Lock Rekeying in Southeastern PA and Northern Delaware

Rekeying changes the cylinder inside a business door lock so its former operating keys no longer work.

You get a different key for that door while keeping the existing hardware, provided it is suitable for rekeying. This gives you a way to control access when an employee leaves, a copy goes missing, or a new tenant takes over a space. It does not affect copies for doors that are left out of the work, so choosing which openings to include matters.

You may want to start with exterior entrances and doors to areas that hold inventory, records or equipment. We can arrange selected doors to work with one shared key where the hardware allows, or keep access separate for different areas. If your building uses a master key plan, we can rekey selected doors to fit that plan when the hardware and system allow it. An existing master key may still open those doors, even though their former individual keys no longer do. If a cylinder is worn or cannot be rekeyed to the arrangement you need, replacing it may be an option. The choice comes down to which doors need restricted access and who needs broader access across the building.

When you call, tell us which business doors you want rekeyed and which keys need to keep working.

A door list, the keys you have and any record of your existing master key plan give us a useful starting point. You can choose exterior entrances, shared spaces or selected rooms rather than every door. We will ask how you want access divided, including whether one key should operate several doors and whether individual keys should open only certain ones. If you are unsure which doors belong in the plan, we will work through the choices with you.

We examine the locks and available keys, then explain whether the doors can fit your existing master key plan or need a different arrangement. Keeping an existing master key means it will still operate any door assigned to it, so tell us if a copy of that key is among those you no longer trust. We rekey the selected cylinders and test the keys assigned to each door, including any master key meant to remain active. You receive the working keys and an account of which doors they operate, so you can distribute them according to your access plan.
