Locksmiths questions, answered by experts

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.

First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.

You might assume that having two locks on one door will offer more protection than only one lock, but there may not be an advantage. While there’s nothing wrong with having two locks if you feel it’s best for your living situation, rest assured having one high-quality deadbolt installed correctly will offer a high level of protection.

The cost to rekey locks on your home is $40 to $100 plus $15 to $40 per lock. Rekeying means you can keep your existing locks but simply change the key. You’ll still need a pro to cut a new key and rekey the lock, but no new hardware is required. Rekeying is a good option if:

  • You need a quick way to upgrade your current locks

  • You have a quality lock that works well

  • You recently moved in and want to ensure you’re the only one with access

  • You lost a key

Although you should rekey your locks after moving into a new home, you may feel more comfortable replacing the locks entirely. Here are some other scenarios when you should replace your locks rather than rekey them:

  • When someone moves out of your home.

  • There are too many copies of the existing key.

  • Your home experiences any type of break-in.

  • You lose your key with the address on it.
