When you lose your house key, or when a roommate moves out, you may consider getting new locks just to make sure no one enters with a key who isn't supposed to. You might have another option, and that's rekeying the locks rather than replace them. Here are some times rekeying could be an option and when replacement is better.
Reasons To Have Your Door Lock Rekeyed
Rekeying is the process of changing the pins inside your existing lock so your old key no longer works.
Life's full of changes—some of them expected while others can be entirely unpredictable. Some changes may even require you to have your door locks changed at some point. But instead of having the entire lock changed, you can instead have your locks rekeyed. Rekeying a door lock lets you keep your original lock while changing the key used to secure it.
During a rekeying, the locksmith simply changes or rearranges the key pins inside the lock's tumbler, in effect making the old key useless.
