How To Rekey a Lock

Have you ever found yourself needing to change the key that operates a lock without replacing the entire lock itself? Rekeying a lock allows you to do just that. Whether you've moved into a new home, lost a key, or wish to enhance your security, knowing how to rekey a lock can be a valuable skill. In this blog post, we will provide you with a comprehensive step-by-step guide to help you rekey a lock like a pro.

Step 1: Gather the Necessary Tools:

To successfully rekey a lock, you will need a few essential tools:

Key pins and key springs (available in a rekeying kit)

A plug follower

A pinning tray or a small container

Tweezers or needle-nose pliers

A screwdriver (usually flathead or Phillips, depending on the lock)

Step 2: Remove the Lock Cylinder:

Begin by removing the lock cylinder from the door. Depending on the type of lock you have, you may need to unscrew a retaining screw or use a key to release the cylinder.

Step 3: Take Apart the Lock Cylinder:

Carefully disassemble the lock cylinder. You will typically find a retaining cap, cylinder plug, and springs inside. Use the plug follower to prevent the springs and pins from falling out during the process.

Step 4: Remove the Old Pins:

Dump the old pins out of the cylinder and set them aside. Take note of the pin lengths and order for future reference.

Step 5: Determine the New Key Pin Configuration:

Examine the new key and determine the pin configuration required to match it. The key pins will have different lengths, and each corresponds to a specific cut in the key.

Step 6: Install New Key Pins:

Begin installing the new key pins into the corresponding chambers within the cylinder plug. Start with the first pin, align it with the correct chamber, and gently press it in using the tweezers or needle-nose pliers. Repeat this process for each chamber, ensuring that the pins align flush with the shear line.

Step 7: Reassemble the Lock Cylinder:

Carefully reassemble the lock cylinder, ensuring that the key pins and springs remain in their respective chambers. Use the plug follower to guide the cylinder plug back into place, and secure it with the retaining cap or screws.

Step 8: Test the New Key:

Insert the new key into the lock and test its functionality. The key should turn smoothly, and the lock should operate correctly. If any issues arise, disassemble the lock cylinder again and double-check the pin placement.

Step 9: Reinstall the Lock Cylinder:

Once you are confident that the lock is functioning correctly with the new key, reinstall the lock cylinder back into the door. Ensure it is securely fastened according to the manufacturer's instructions.

Conclusion:

Rekeying a lock is a practical skill that can save you time and money, providing an effective way to change keys without replacing the entire lock. By following this step-by-step guide, you can confidently rekey a lock yourself. Remember to exercise caution and take your time during the process to avoid any mishaps. With practice, you'll become proficient in rekeying locks, giving you the flexibility and convenience of managing your own security needs.
