What is a locksmith pinning chart?

Answer by  Deb43 (579)

Locksmith pinning charts are templates used by locksmiths to determine the location and lengths of the pins used in locks so they can open them. There are a variety of random combinations based on number and lengths of pins that are used to keep locks closed. This chart provides a guide for commonly used combinations.

This chart helps locksmiths determine how to open or repair a specific kind of lock called a pin tumbler lock (also referred to as a Yale lock). This lock uses pins of different lengths to stay secure, so repairing it requires a chart that gives all of the pin lengths.
