Great Openings Control Keys
The control key is a key that is required for the removal and installation of lock cores. It does not lock or unlock your lock like a regular key. Some locks must be in the unlocked position to remove the lock core. A Control Key is also referred to as a Pull Key, Change Key or Core Removal Tool.
