Locksmith in Merion, PA

We adjust the strike or realign the bolt so the deadbolt and strike line up cleanly; if the cylinder is worn we service or replace it. Until we get there, be gentle with the key and do not put oil in the lock. Have the door tested open and closed a few times so you can describe exactly when it sticks.

Usually we rekey the exterior locks so they all work on a single key where the hardware allows; if a particular lock cannot be rekeyed we’ll identify which one should be replaced. Gather every current key for the doors you want on one key and note which doors are exterior versus interior so we can plan the job.

For a business we can rekey the affected locks so the old keys stop working, replace cylinders or entire locks if needed, and set up a master key system if you want one. Have a list of doors and who should receive keys ready before we start. Before we change any lock, we look at your ID and a document that shows you are the owner or manager.

Often we service the original mortise lock, tightening loose parts and replacing worn components; if the set is beyond repair we fit a replacement that matches the door and avoid cutting new holes when possible. Make a note of the symptoms: sticking, loose trim, or a stiff key, and which door and side the lock is on.
