Why Rekeying a Lock Matters

Before delving into the details of how to rekey a lock, it’s essential to understand why it’s a crucial security measure.

Enhanced Security: Rekeying a lock allows you to change the key that operates it while keeping the existing lock mechanism intact. This ensures that anyone with the old key will no longer have access, significantly enhancing security.

Cost-Effective: Rekeying is typically more cost-effective than replacing an entire lock system. It allows you to achieve improved security without the expense of purchasing new locks and handles.

Convenience: Rekeying a lock is a relatively quick process when performed by a professional locksmith. It’s a convenient way to bolster security without causing significant disruption to your daily routine.

Customization: Rekeying gives you the opportunity to create a master key system, where one key can open multiple locks. This can be particularly useful for business owners or homeowners with multiple entry points.

Peace of Mind: Knowing that you have exclusive control over who has access to your property can provide peace of mind and a heightened sense of security.

The Rekeying Process

Now that we understand the importance of rekeying a lock let’s dive into the steps involved in the process.

Gather Your Supplies
Before you begin, make sure you have all the necessary tools and materials. These typically include a screwdriver, a key decoder, a new set of pins and springs, a key cutting machine (if you’re doing it yourself), and, most importantly, the new key or keys you want to use.

Remove the Lock Cylinder
To start the rekeying process, you’ll need to remove the lock cylinder from the door. Follow these steps:

a. Use your screwdriver to remove the screws holding the lock faceplate in place.
b. Once the faceplate is removed, you can access the cylinder. Use the screwdriver to take out the retaining screw located at the back of the cylinder.
c. Slide the cylinder out of the lock assembly.

Disassemble the Lock Cylinder
Now that you have the lock cylinder removed, you can disassemble it. Here’s how:

a. Remove the C-clip or retaining ring from the back of the cylinder.
b. Carefully slide the plug (the part of the cylinder that turns when you use the key) out of the cylinder housing.
c. Remove the old pins and springs from the plug.

Determine the New Pin Configuration
This step is where the key decoder comes into play. Use it to determine the new pin configuration for your lock based on the new key or keys you want to use. Each pin corresponds to a specific cut on the key, and you’ll need to match them accordingly.

Insert the New Pins and Springs
Once you have the new pin configuration, insert the new pins and springs into the plug. Be sure to follow the order and placement determined by the key decoder.

Reassemble the Lock Cylinder
With the new pins and springs in place, reassemble the lock cylinder in the reverse order of disassembly:

a. Slide the plug back into the cylinder housing.
b. Reattach the C-clip or retaining ring to secure the plug.
c. Insert the cylinder back into the lock assembly on the door.
d. Reattach the retaining screw at the back of the cylinder.
e. Place the lock faceplate back onto the door and secure it with screws.

Test the New Key
Once the lock cylinder is reassembled, it’s time to test the new key. Insert it into the lock and make sure it turns smoothly and operates the lock as intended.

Rekey Other Locks (Optional)
If you’re rekeying multiple locks to work with the same new key, repeat the above process for each lock.

Dispose of Old Keys
For enhanced security, it’s essential to ensure that old keys are no longer in circulation. You can either collect and destroy them or keep them in a secure location, such as a safe, if you ever need them for reference.

Consider a Master Key System (Optional)
If you have multiple locks on your property and want the convenience of a master key system, consult with a locksmith about creating a master key that can open all of them. This can simplify access control while maintaining security.

Professional Assistance

While the steps outlined above may seem straightforward, rekeying a lock can be a delicate process, and mistakes can lead to security vulnerabilities. It’s advisable to seek the assistance of a professional locksmith, especially if you’re unsure about your skills or if you have complex lock systems to rekey. Your Trusted Locksmith in Brampton
