How to measure a cylinder lock
A cylinder lock is a lock mechanism that uses pins of various lengths to help lock the lock by the incorrect key. The first main advantage to a cylinder lock, also known as a profile cylinder lock or euro, is that the cylinder can be changed without altering the bolt work hardware.
The first know pin tumbler lock was found in the ruins of the Palace of Khorsabad in Iraq, but the basic principles of the pin tumbler lock may date back as far as 2000 BC in Egypt.
