Should I change my locks after buying a house? Without a doubt! Security should be your first concern when you move into a new house. Previous homeowners most likely had a few extra sets that they gave to neighbors, relatives, friends, or even contractors. I don’t know about you, but the idea of strangers having quick and easy access to my home is unacceptable. Especially after moving into a new home, you want to feel safe and secure when you lay down your head at night.
Lost or Stolen Keys
If your keys have potentially fallen into the wrong hands, It’s always better to be safe than sorry. Even if you have no identifying address information on your keychain, the number one reason for change your locks after losing keys is security! If they were lost, or dropped near your home, someone may find them and try the nearest doors just for luck. And even if your keys are returned, it’s hard to be sure they weren’t copied while they were out of your hands.
New Roommate or Tenant
If you rent out space in your home, protect yourself by replacing locks every time you change tenants. You will gain peace of mind knowing that your locks are secure and protected, and you won't have to suspect your past tenants in the event of a break-in. Even if the last tenant turned in their key, you can't be sure they didn't make a backup copy. They may not even remember having given a copy of their key to a neighbor or friend in the past.
Wear and Tear
Worn or rusted locks are a serious weakness in home security. Old, worn out locks are easier to pick and break, and they are more difficult to open legitimately with a key as time goes on. If your lock is becoming increasingly difficult to open with the key, you need to replace or service the lock immediately to avoid an inconvenient malfunction that may leave you locked out or locked in your own house.
