In this day and age when electronic locks are becoming more and more popular, we should not forget the old reliable mechanical locks known as the cylinder locks. The cylinder lock will always be known as one of the most dependable among the mechanical door locks of years past.

The function of your standard cylinder door lock is based on use of a built-in cylinder that has to be rotated for your lock to open. The cylinder lock will generally be held in place along with a host of different lock systems as well. Some of these lock systems you may be familiar with are the disc tumbler lock system, the wafer tumbler lock system, and the pin tumbler lock system.
