Dec 12, 2025Leave a message

Rekeying a deadbolt door lock is a handy skill that can save you time and money. As a deadbolt door lock supplier, I've seen firsthand how important it is to know how to do this yourself. Whether you've just moved into a new place or lost your keys, rekeying your deadbolt can give you peace of mind and increased security. In this blog, I'll walk you through the process step by step.

What You'll Need

Before you start, gather the following tools and materials:

  • A rekeying kit: You can find these at most hardware stores. Make sure it's compatible with your deadbolt model.
  • A Phillips head screwdriver: Most deadbolts are secured with Phillips head screws.
  • The old keys: You'll need these to remove the pins from the lock.
  • A new key: You can buy a blank key from a hardware store and have it cut to fit your new keyway.

Step 1: Remove the Deadbolt

First, you'll need to remove the deadbolt from the door. Use your screwdriver to remove the screws on the inside of the door. These screws are usually located on the faceplate of the deadbolt. Once you've removed the screws, gently pull the deadbolt out of the door.

Step 2: Disassemble the Deadbolt

Now that you have the deadbolt out, it's time to disassemble it. Look for the retaining clip or screw that holds the cylinder in place. Use your screwdriver or a small tool to remove this clip or screw. Once it's removed, you should be able to pull the cylinder out of the deadbolt housing.

Step 3: Remove the Pins

The pins inside the cylinder are what make the lock work. To rekey the lock, you'll need to remove these pins. Insert the old key into the cylinder and turn it slightly to the locked position. This will align the pins so you can remove them. Use the pick tool from your rekeying kit to push the pins out of the cylinder. Be careful not to lose any of the pins.

Step 4: Rearrange the Pins

Now that you've removed the pins, it's time to rearrange them according to the new key. Your rekeying kit should come with a set of instructions that show you how to do this. Usually, you'll need to place the pins in a specific order to match the cuts on the new key. Make sure you follow the instructions carefully.

Step 5: Reassemble the Deadbolt

Once you've rearranged the pins, it's time to reassemble the deadbolt. Insert the cylinder back into the housing and replace the retaining clip or screw. Make sure the cylinder is properly aligned and secured. Then, insert the new key into the cylinder and turn it to make sure it works.

Step 6: Install the Deadbolt

Now that you've rekeyed the deadbolt, it's time to install it back into the door. Line up the deadbolt with the hole in the door and insert the screws. Use your screwdriver to tighten the screws securely. Make sure the deadbolt is properly aligned and functions smoothly.
