If your alarm is setup to work with a different key then you have with the 820 series keys, this will let you change the lock position to the key of your choice. Say you have the 820-1 key, but the lock is set at 820-5, this will allow you to move the lock to the 820-1 position without setting off the alarm. This would then allow you to enable/disable the alarm. This is for personal/professional use only if you own a protex alarm system or you are a locksmith! Any questions please feel free to
