Rekeying a lock is a simple and cost-effective way to enhance the security of your home or property without having to replace the entire lock. Whether you’ve lost your keys, recently moved into a new place, or simply want to prevent access to old key holders, rekeying allows you to update your locks quickly and efficiently.
This guide on how to rekey a lock will walk you through the process step-by-step, ensuring you can complete the task confidently and safely.
What is Rekeying?
Rekeying is the process of changing the internal components of a lock so that it can only be operated by a new set of keys. Instead of replacing the entire lock mechanism, rekeying involves adjusting the pins or tumblers within the lock to match a different key’s profile. This means that the old key will no longer work, effectively maintaining security without the cost and hassle of installing a completely new lock.
Rekeying is a practical solution in many scenarios, such as after losing your keys, moving into a new property, or enhancing security following a change in occupants.
Why Rekey Instead of Replace?
Rekeying offers several advantages over completely replacing a lock. First and foremost, it is a cost-effective solution. Since the lock mechanism remains intact, you only pay for the labor and new keys, rather than the expense of purchasing an entirely new lock.
Additionally, rekeying is quicker and less invasive, as it does not require removing and installing hardware. It is also an environmentally friendly option, reducing unnecessary waste by reusing existing materials.
Finally, rekeying allows for customization; for instance, you can rekey multiple locks to work with the same key, enhancing convenience without compromising security. These benefits make rekeying an appealing and efficient choice for many situations.
Needed Materials
To successfully rekey a lock, you will need a few key materials. These include:
A Rekeying Kit:
This typically includes special tools such as pins and springs that are used to change the inside of the lock cylinder. It may also contain additional keys for your locks.
A Key Decoder:
This tool is used to determine the correct positions for the pins inside the lock cylinder. It helps ensure that your newly rekeyed lock will work smoothly with your new key.
A Pair of Pliers:
These are used to remove and replace the springs and pins in the lock cylinder.
8 Step-by-Step Guidelines on How to Rekey a Lock
Step 1: Remove the Lock From the Door
Begin by carefully removing the lock from the door. Depending on the type of lock, this may involve unscrewing screws on the interior side of the door or disengaging mounting hardware.
Use a screwdriver to loosen and remove all visible screws holding the lock mechanism in place. Once detached, gently pull the lock assembly out of the door. Be sure to keep all screws and small components in a safe place to avoid losing them during the rekeying process.
Step 2: Take Out the Old Key
Insert the old key into the lock cylinder and turn it slightly to the right or left, depending on the lock’s design. This small rotation will align the cylinder’s inner pins, making it possible to slide the plug out later.
Keep the key in this position as you proceed with the following steps, ensuring that the cylinder is ready for rekeying.
Step 3: Use the Key Decoder
With the old key still in the lock cylinder, use a key decoder to determine the correct pin placements for the new key. The decoder typically works by matching the grooves on the key to corresponding numbers or depths.
Carefully note these measurements, as they will guide you in adjusting the lock pins to fit the new key. This step is crucial to ensuring that the rekeying process results in a perfectly functioning lock.
Step 4: Remove Top Pins
Remove the old top pins from the lock cylinder to prepare it for the new configuration. Using a pair of tweezers or a pinning tool, carefully extract the top pins one at a time, ensuring not to lose any components in the process.
Place the removed pins in a secure location to prevent them from mixing with the new pins. This step clears the way for the new key to be inserted into the lock without any obstructions.
Step 5: Insert New Key
Insert the new key into the lock cylinder to ensure it is properly aligned for the re-pinning process. Once the key is fully inserted, double-check that it sits flush within the cylinder and rotates smoothly without resistance.
This alignment is crucial as it determines how the new pins will fit into the lock. Take your time during this step to avoid any misalignment that could affect the functionality of the lock.
Step 6: Add New Bottom Pins
Using the rekeying kit, select the bottom pins that correspond to the cuts on the new key. Carefully place each pin into the appropriate pin chamber within the lock cylinder. Ensure that each pin is seated securely and aligns evenly with the cylinder when the new key is inserted.
The pins should sit flush with the shear line to allow the cylinder to rotate smoothly. Take your time during this process to prevent errors that could impact the lock’s operation.
Step 7: Test the Lock
Once the new pins are installed, reassemble the lock by carefully reinserting the plug into the lock cylinder. Be sure the pins remain aligned and do not shift during this process. Secure all components, including the retaining clip, and insert the new key.
Test the lock by turning the key to confirm smooth operation. If the lock does not turn easily or jams, disassemble it to check for misaligned pins or other issues. Repeat the testing process until the lock operates correctly with the new key.
Step 8: Reassemble and Clean Up
Reattach any removed parts such as the faceplate or doorknob. Use a lubricant on the key and inside of the lock to keep it functioning properly. Finally, clean up any tools or debris used during the process.
Following these steps on how to rekey a lock can save you time and money compared to calling a locksmith. It is important to note that rekeying a lock will not change the physical hardware of the lock, so it is still possible for someone with the old key to gain entry. For added security, consider replacing your locks entirely if you have concerns about who may have access to your keys.
Additional Tips
- Keep track of your old pins and their corresponding slots in case you need to revert to them.
