Do I Need To Leave The "ON/OFF" Switch "ON"?

Edited

The "ON/OFF" switch only controls the remote fobs. You will need to leave the switch "ON" for your fobs to operate the lock. If the switch gets turned "OFF", your remote fobs will no longer work but the keypad will. Turning this to the "OFF" position will not erase the remote fob(s) from the lock.
