Re - keying a euro cylinder lock is a valuable skill that can enhance security and provide convenience. As a cylinder lock supplier, I've witnessed firsthand the importance of understanding how to re - key these locks. In this blog, I'll guide you through the process of re - keying a euro cylinder lock, from the tools you need to the step - by - step procedure.

Why Re - key a Euro Cylinder Lock?

There are several reasons why you might want to re - key a euro cylinder lock. Firstly, if you've lost your keys, re - keying the lock is a more cost - effective solution than replacing the entire lock. Secondly, when you move into a new property, you have no idea how many copies of the keys exist. Re - keying ensures that only you and the people you trust have access. Additionally, if you've had a security breach or suspect that someone has unauthorized access to your keys, re - keying can restore your peace of mind.

Tools Required

Before you start re - keying a euro cylinder lock, you'll need to gather the following tools:

  1. Re - keying kit: This kit typically includes pins of different sizes, springs, a pinning tray, and a tension wrench. Make sure to choose a kit that is compatible with euro cylinder locks.
  2. Screwdriver: You'll need a screwdriver to remove the lock from the door. The type of screwdriver depends on the screws used in your lock.
  3. Key: You'll need the original key for the lock or a key blank that matches the lock's profile.

Step 1: Remove the Euro Cylinder Lock

The first step in re - keying a euro cylinder lock is to remove it from the door. Use the screwdriver to remove the screws that hold the lock in place. Carefully pull the lock out of the door. Some euro cylinder locks have a thumbturn on the inside, which may require additional steps to remove. Refer to the lock's manual if you're unsure.

Step 2: Disassemble the Cylinder

Once you have removed the lock from the door, you need to disassemble the cylinder. Place the cylinder on a clean surface and use the tension wrench to apply light pressure to the keyway. This will help keep the pins in place while you work. Insert the original key into the keyway and turn it slightly to align the pins.

Using a pick, carefully push each pin up until it reaches the shear line. The shear line is the point where the plug and the housing of the cylinder meet. As you push each pin up, use the tension wrench to turn the plug slightly. Once all the pins are at the shear line, the plug should turn freely. Remove the plug from the housing.

Step 3: Remove the Old Pins

With the plug removed, you can now remove the old pins and springs from the plug and the housing. Place the plug in the pinning tray and use a pick to push out the pins and springs. Be careful not to lose any of the small parts. You can use a magnet to help collect the pins and springs.

Step 4: Select the New Pins

The next step is to select the new pins for your lock. The size of the pins you need depends on the cuts on your new key. Most re - keying kits come with a chart that shows which pin sizes correspond to each key cut. Compare the cuts on your new key to the chart and select the appropriate pins.

Step 5: Insert the New Pins

Once you have selected the new pins, it's time to insert them into the plug and the housing. Start by inserting the springs into the holes in the housing. Then, insert the pins on top of the springs. Make sure to insert the pins in the correct order and with the correct sizes.

Place the plug back into the housing and use the tension wrench to apply light pressure. Insert the new key into the keyway and turn it slightly to align the pins. As you turn the key, the pins should align at the shear line, allowing the plug to turn freely.

Step 6: Reassemble the Lock

After inserting the new pins, reassemble the lock. Make sure all the parts are properly aligned and that the plug turns smoothly. Once the lock is reassembled, test the new key to make sure it works. Insert the key into the keyway and turn it to lock and unlock the mechanism.

Step 7: Install the Lock Back on the Door

Once you have tested the new key and the lock is working properly, it's time to install the lock back on the door. Use the screwdriver to re - attach the lock to the door. Make sure the lock is securely fastened and that the door closes and locks smoothly.
