Keep the lock, change the key

Rekeying resets the pins inside the cylinder you already have. The lock stays on the door, it keeps working exactly as it did, and every key that existed before stops opening it.

How a rekey goes

Most rekeys are one visit, and the lock never comes off the door frame.

✓
The cylinder comes out. The lock body stays on the door.
✓
The pins are changed to a new combination, so no old key fits.
✓
New keys are cut and tested in the lock before we leave.
✓
Several locks on one key, if they are the same type and you ask for it.

Questions people ask

What does rekeying actually change?

The pins inside the cylinder. The lock stays on the door and works the same way, but every old key stops working.

I just moved in. Should I rekey?

Yes. You cannot know how many copies of the old key exist, and a rekey settles it.

Can every lock be rekeyed?

Most can. A lock that is worn out or damaged is better replaced, and we will say so.
