Once the outside handle is locked with the button on the inside handle, turn the inside handle to release the lock or unlock it with a key from the outside. These are also known as entrance handles.

The outside handle is always locked and has to be unlocked with a key while the inside handle can always open the door. These are also known as storeroom handles.

To help maintain security, these handles unlock with combinations, key fobs, or access cards you can program as needed.
