How do I measure a profile cylinder?

Measuring a euro cylinder is a relatively simple task that you can complete in just a few steps. Here are the steps you should follow:

• First, you need to remove the euro cylinder from the door. You do this by loosening the screw that is usually located on the edge of the door, at the level of the lock.
• Then pull the key out slightly and turn it to remove the euro cylinder from the door. Make sure the key is not pulled out completely, otherwise the pin in the cylinder will block.
• Next, use a ruler or measuring tape to measure the length of the cylinder. You must measure from the center of the fixing hole to both ends of the cylinder.
• Make sure to measure both sides separately. This is usually two measurements separated by a slash, e.g. 30/40.
• Don’t forget to note down the results before buying a new cylinder.

By measuring correctly, you ensure that the new euro cylinder fits perfectly in your door and that the lock functions properly afterward.
