Lock Rekeying in King of Prussia, PA

A contractor who had a key during a project may still have a copy, even if the one you handed over has been returned.

If you live in King of Prussia and no longer want that key to open your home, we rekey the locks you choose. We change the small parts inside each existing cylinder so the old keys no longer work and a different key opens it. The visible hardware and the door stay in place.

Rekeying is also an option when you move in, a roommate leaves or a key goes missing. You can choose which entrances to include, such as the front, back or side door, based on who has had access to each one. If you want one key for all your outside entrances in King of Prussia, the locks need to be compatible. We can check whether that is possible. Replacing the hardware is another choice if it is worn, damaged or you want a different style, rather than keeping what is already there.

If a contractor had a key during your project, we first look at the locks on the doors that key could open.

We check their condition and whether they use compatible keys. Before work starts, we explain your choices for which doors to include, whether one new key can operate them, and which locks would need separate keys. Rekeying changes the pins inside the existing cylinders, not the visible hardware. A lock that is worn or damaged may be a better candidate for replacement.

Once you have chosen which doors to include, we rekey the selected locks and provide new keys. With you, we check each door, testing the new key in each keyed side and making sure the door latches properly. If you still have an old key, we can test it against the rekeyed locks too. A door left out of the work keeps its existing key, so you can decide whether that access still suits you. If a key or lock does not work as expected during the check, we look into the problem and explain what we find.

After a roommate moves out, keep track of who has copies of the new key.

Give spares only to people you trust, and avoid attaching your address to a key ring. If any outside doors were left out of the rekeying, their old keys may still work. Consider whether those entries need the same change. Store a spare with someone you trust rather than hiding it outside.

With the door open, test the new key and, if you have one, the old key. The new one should turn smoothly, while the old one should not turn the lock. Check that the door latches and locks when closed, keeping your new key with you. If it sticks, avoid forcing it or flooding the opening with household oil. Use a lubricant labeled for locks according to its directions. Call us again if an old key still works, a new one catches, or the door does not secure properly.
