Side pin

=Side pin=



A side pin (or finger pin) is an active locking component used in many locks. Side pins are widely used on high-security locks to provide a secondary locking mechanism, enhance key control, and increase the number of available differs for a keying system. Individual side pins are often used in cylinder-based locks to prevent rotation of the plug until the proper key is used. Almost all sidebar locks use side pins in some way.

Keys for locks that use side pins or sidebar often have a secondary bitting surface to interact with side pins.

The Schlage Everest is one of the most notable examples of a lock that uses a single side pin.
