Should I Change My Locks After Buying a House?


Security should be your first concern when you move into a new house. Most people create spare copies of their keys, so the previous homeowners likely had a few extra sets that they gave to trusted neighbors, family members, friends, or even contractors. I don’t know about you, but the idea of strangers having quick and easy access to my home is unsettling. Especially after moving into a new home, you want to feel safe and secure when you lay down your head at night.


If you want to feel confident in your new home’s security, you have two options:


  1. You can change your locks.

  2. You can rekey your locks.


Replacing your locks is the more expensive, invasive, and complicated method. You will have to remove the entire lock (or two or three or eight locks . . .) and replace it with another model. This option is recommended if you don’t feel the current locks are reliable or you’d like to upgrade to stronger, more efficient locks.


If you’re pleased with your home’s locks but you’re afraid extra copies of the key are floating around, you have a simpler option: rekeying. When you rekey a lock, you change the lock so that it can be operated by another key. This is done by altering the tumbler, changing the water configuration, or forcing a new key exchange. After the lock has been rekeyed, the new key can operate the lock and the old key is invalidated.

It’s a simple, quick, and affordable process. So don’t forget and don’t underestimate the importance of rekeying. If anything should happen in the years that follow this move, it will be hard to forgive yourself.
