Preparation and Safety
Before starting, ensure you have the correct rekeying kit for your lock model. Work in a clean, well-lit area. Wear safety glasses if necessary, and keep small parts organized to avoid losing them during the process.
Step-by-Step Rekeying Process
1. Remove the Lock from the Door
Using a screwdriver, carefully remove the mortise lock from the door. Keep track of all screws and parts.
2. Disassemble the Lock
Open the lock case to access the cylinder. Depending on your lock model, you may need to remove the faceplate or other components.
3. Remove the Cylinder
Carefully extract the cylinder from the lock housing. Be cautious not to damage any internal parts.
4. Identify the Pins
Using the pinning kit, remove the existing pins from the cylinder. Note the current pin sizes and arrangement.
5. Replace with New Pins
Insert new pins that match the cuts of your new key. Use the key gauge to determine the correct sizes. Ensure the pins are seated properly.
6. Reassemble the Cylinder
Reinsert the rekeyed cylinder into the lock housing. Test the new key to verify it turns smoothly and unlocks the mechanism.
7. Reinstall the Lock
Reattach the lock to the door, securing all screws tightly. Test the lock with the new key before completing the process.
Final Tips and Troubleshooting
If the key does not turn smoothly, double-check the pin sizes and reassemble carefully. Lubricate the cylinder with a light spray of lubricant if necessary. Always keep spare keys and pins in case of future rekeying needs.
