How to Replace Lost Door Lock Keys

If you've lost your keys to the door, you'll need to get the lock re-keyed.

Losing door keys can be frustrating, especially if you don't have a spare set of keys on hand (which you always should, just in case this sort of thing happens). When this happens you'll need to get new keys made for your door locks, which means that one way or another you're going to have to get in touch with a locksmith, or a service that can re-key your locks.

Instructions

1. Make sure that you cannot find either your door lock keys or the spare set of keys. Once you're absolutely sure that you need the lock re-keyed, you'll need to locate someone who can perform the service for you.

2. Call local locksmiths and check with home improvement stores that have keying services available. Compare rates, and find out if the service will come to your house to re-key the locks or if you'll need to remove the lock to take it in. If the latter, then you need to unlock the door, open it and from the inside of the door remove the bolts that hold the knob and locking mechanism in place. Obviously, if you're locked out this isn't going to be a possibility.

3. Get your locks re-keyed. Since the job likely exceeds the capabilities of those who don't have training as a locksmith, it's best to trust the professionals to get your new set of door lock keys. Once you have the keys, test them to make sure they work.
