Before Replacing the Door Lock, What You Should Do


Replacing a door lock can be reduced to the following steps: buy a new lock that matches your existing lock’s keyway, change the new lock to your existing house key, remove the old lock, install the new latch, install the new lock body, check for proper latch operation to ensure your lock is secure.

1. Buy replacement locks that are at least a residential grade 2 lock. These locks have anti-bump and pick measures already installed and are more robust than grade 3 locks.


2. Take the locks you bought to your local locksmith so they can rekey them to match your existing house key. This way, you will still have one key for every lock in the house and not be stuck with two keys.

For this to work, you need to buy the same lock brand as your existing lock brand or at least buy one with the same keyway.

3. Before changing your existing door locks, measure the width of your door. Locks you will purchase will all be for standard door widths of 1 3/8 to 1 3/4 inch. If your door is thicker than that you will need to purchase a thick door kit for whatever brand of lock you are replacing. Thick door kits contain longer screws and a longer tail peace (for deadbolt) or spindle extension (for door knobs).

4. Note how far away from the edge of the door the lock is. If the center of your lock is 5” away from the edge, you are going to need to buy an elongated latch and bolt. Your local locksmith will carry these, and we encourage you to support your local locksmith. They will make sure you get the right ones for your door locks.
