Rekeying a Standard Deadbolt Lock
Rekeying a standard deadbolt involves changing the internal pins so that a new key operates the lock. Here’s a detailed breakdown:
1. Gather Your Supplies
You’ll need a rekeying kit specific to your deadbolt’s brand. These kits typically include:
- Key gauge: Helps identify the correct pin sizes.
- Tweezers: For precise handling of small pins.
- Follower tube: Prevents pins from springing out.
- Removal tool: Assists in disassembling the lock.
- New pins: Come in various sizes to match your new key.
- New key: The key that will operate the rekeyed lock.
2. Remove the Deadbolt from the Door
- Extend the bolt: Ensure the deadbolt is in the unlocked position.
- Remove the screws: Locate the screws on the faceplate and interior cylinder. Unscrew them carefully.
- Detach the deadbolt: Gently pull the two halves of the deadbolt apart.
3. Disassemble the Cylinder
- Remove the cylinder retaining clip (C-clip): Use the provided tool to carefully pry off the C-clip holding the cylinder in place.
- Slide out the cylinder: The cylinder should now slide out easily.
4. Remove the Old Pins
- Insert the follower tube: This will hold the pins in place.
- Remove the key plug: Use the removal tool to gently push out the plug.
- Discard the old pins: Keep them separate from the new pins.
5. Install the New Pins
- Insert the new key: This will set the correct pin heights.
- Install new pins using the key gauge and tweezers: Consult the kit instructions for the correct pin sizes and placement. Ensure each pin sits flush.
- Remove the key: Once all pins are in place, carefully remove the key.
6. Reassemble the Cylinder
- Insert the plug back into the cylinder: Gently push it in until it’s flush.
- Remove the follower tube: As the plug goes in, the follower tube will be pushed out.
- Reinstall the C-clip: Secure the cylinder in place.
7. Reinstall the Deadbolt
- Insert the cylinder back into the housing: Ensure it aligns correctly.
- Reattach the two halves of the deadbolt: Align the screw holes and secure them with the screws.
- Test the lock: Check that the new key operates the deadbolt smoothly.
Rekeying Smart Locks
Rekeying smart locks varies greatly depending on the brand and model. Some smart locks utilize keypads or smartphone apps and don’t have traditional key cylinders. Others have backup physical keys. Consult your smart lock’s manual for specific rekeying instructions or contact the manufacturer. In some cases, rekeying may not be possible, and you might need to replace the lock entirely.
A Final Note on Security
While rekeying is a valuable security measure, consider upgrading to a high-security deadbolt with features like anti-bump and anti-pick resistance for enhanced protection. If you’re unsure about any step in the rekeying process, consult a qualified locksmith.
