Step-by-step Process for Rekeying a Deadbolt Lock

by

Rekeying a deadbolt lock is a practical skill that can save you money and increase your home security. Instead of replacing the entire lock, rekeying allows you to change the internal pins so that only new keys work with your existing lock. This guide provides a clear, step-by-step process to help you rekey your deadbolt lock efficiently.

Tools and Materials Needed

  • New key pins and driver pins (matching your new key)
  • Small screwdriver or pinning kit
  • Plug follower or a similar tool
  • Key for the current lock
  • Replacement key (if available)
  • Lubricant (optional)

Step-by-Step Rekeying Process

1. Remove the Deadbolt Lock

Start by removing the deadbolt lock from your door. Use a screwdriver to unscrew the screws securing the lock on both sides of the door. Carefully pull out the lock mechanism.

2. Remove the Cylinder

Locate the cylinder inside the lock. Remove the retaining clip or screw that holds the cylinder in place. Gently pull out the cylinder, exposing the plug where the pins are housed.

3. Remove the Old Pins

Insert the current key into the cylinder and turn it slightly. Using a small screwdriver, carefully remove the plug from the cylinder. This will reveal the pins and springs inside. Remove the old pins from the plug.

4. Insert New Pins

Match the new pins to your new key. Insert the driver pins and key pins into the plug, ensuring they align correctly with the new key’s cuts. Use the pinning kit or small tweezers for precision.

5. Reassemble the Cylinder

Carefully reinsert the plug into the cylinder, ensuring the pins are properly seated. Reattach the retaining clip or screw to secure the cylinder in place. Test the new key to ensure it turns smoothly.

6. Reinstall the Deadbolt

Place the rekeyed cylinder back into the lock body. Secure it with the retaining screw or clip. Reattach the lock to your door and tighten all screws securely.

Final Tips

  • Always test the new key before fully reinstalling the lock.
  • Lubricate the lock with a graphite-based lubricant for smoother operation.
  • Keep your new keys in a safe place and consider making copies for family members.

Rekeying your deadbolt lock is a straightforward process that enhances your home’s security. With patience and the right tools, you can do it yourself and enjoy peace of mind knowing only your new keys will operate the lock.
