Are you locked out because you’ve lost your key? Or is your euro cylinder lock just acting up? Don’t worry; we’ve got your back. In this guide, we’ll show you how to remove a euro cylinder lock without a key. This essential skill can save the day when you’re locked out of your home or need to change your lock, even if you don’t have a spare key. Let’s dive in!

What you need to remove a euro cylinder lock without a key

Before we get started, let’s gather the tools you’ll need:

  • Screwdriver: The type of screwdriver you’ll need depends on the screws in your lock. If you have cross-shaped screws (Phillips), use a Phillips screwdriver. If your screws have internal hex heads, you can use an Allen wrench.
  • Paper Clip or some other thin metal object: This will serve as an alternative to the lost or broken key. Ensure it’s made of metal and straighten it out.

Now that we’ve got our tools ready, let’s go through the steps to remove a euro cylinder lock without a key.

Step 1: Locate the position of the lock and unscrew the front side

Start by finding the location of your Euro cylinder lock. Look for the area where you insert your key. There, you’ll find a piece of metal securing the lock’s body, known as the escutcheon plates. Typically, there are two screws, one on the upper part and another on the lower part of this metal piece. Unscrew these screws to uncover the lock’s body.

Step 2: Remove the screw inside the lock’s body

The screw that locks the cylinder is located inside the door cavity. It’s this screw that holds the euro-cylinder lock in place. Locate this screw and start unscrewing it. Be careful not to remove the nuts that hold the faceplate.

Step 3: Turn the Cylinder Cam into a 12 o’clock position

Now comes the tricky part since you don’t have a key. Take your straightened metal paper clip and insert it into the right side of the lock, just above the cylinder cam. Apply pressure to push the cylinder cam downward until it goes into the lock. This step is crucial for the next one.

Step 4: Eject the lock from the cavity of the door

Once you’ve successfully completed the previous steps, you can now eject the lock from the door’s cavity. If the lock is old and worn out, this should be relatively easy. However, if the lock is newer, it might take a few attempts, especially if this is your first time using this technique.

Changing the lock without a key

If you need to change the lock without a key, the process is similar up to Step 3. Once you’ve turned the cylinder cam into a 12 o’clock position, you can remove the old lock and replace it with a new one. This step might require professional locksmith service, especially if you’re not confident in your DIY skills.

Safety precautions

While performing these tasks, it’s essential to prioritise safety:

  • Safety Gear: Wear safety glasses and gloves to protect your eyes and hands during the process.
  • Adequate Lighting: Ensure you have enough lighting to see clearly. Consider using a flashlight for dimly lit areas.
  • Secure the Door: Make sure the door won’t unexpectedly close or move while you’re working. Use doorstops or have someone hold the door steady.
  • Keep Small Parts Secure: Use a container or plastic bag to collect small parts and screws as you remove them. This helps to prevent them getting lost.


By following these steps, you can remove a euro cylinder lock without a key, allowing you to regain access to your home when you’re locked out or change your lock when necessary. Remember to prioritise safety, and if you’re unsure about any part of the process or need to install a new lock, don’t hesitate to contact us for professional help. You’ve got this!
