What is Euro profile Mortise Lock?

Euro Profile mortise door lock is a cylinder-shaped lock. In some cases, they are also called door barrels. In these locks, if the key pattern matches the pins inside the lock, you can turn the key. Once the key is turned successfully, the middle part of the cylinder, known as the cam, will also turn. And when the cam is activated, the door locks will be locked or unlocked.

This lock offers protection and security to a variety of properties, both domestic and commercial. However, since the euro cylinder lock is so easy to install, modify with additional security measures, or replace, it is one of the most commonly used lock profiles by locksmiths and architectural ironmongers.
