Frequently Asked Questions

What is a half cylinder used for?

A half cylinder is used when keyed access is only needed from one side of the door, such as on doors with a thumb-turn on the interior or where no interior access is required.

What does European keyway mean?

European keyway refers to the key profile standard commonly used in European-style locks and cylinders, which differs from American cylinder keyways.
