Answer: When activated the lock will say "Secure Lock is on" and not allow you to enter any codes, fingerprints, fobs to unlock it. You can only unlock using the app when this is turned on. You can deactivate this setting by going to settings. Tap on "Privacy Lock", and then turn it off.

The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key to open it and gain access. In more complex mechanical lock/key systems, two different keys, one of which is known as the master key, serve to open the lock.

To make a new key for an existing lock, you cut a series of notches in the key so that it raises each of the upper pins just above the shear line. Essentially, you cut a pattern in the metal that matches the pattern of the pins in the lock.
