Question: 1 / 435

In lock terminology, what does 'Hand Change' signify?

A method to change the lock mechanism

A lock design requiring wheel removal for combination changes

The term 'Hand Change' in lock terminology specifically refers to the process that involves removing the wheels of a lock in order to change its combination. This typically applies to combination locks, particularly those with mechanical configurations that use rotating wheels. When a lock is designed this way, the combination can only be altered effectively by physically accessing the interior components, often necessitating the removal of the wheels.

In the context of this term, it indicates that a more involved, precise manipulation of the lock's internal workings is required rather than simply adjusting settings or dials externally. Understanding this aspect of 'Hand Change' is crucial for locksmiths when performing maintenance or servicing of combination locks.
