ABSTRACT:
A multiple dial lock includes reset dials rotatable around a lock shaft. Each reset dial must be at a specific angular position for a user to unlock the lock or reset the combination. Each reset dial has a magnet. A master key includes sensors, each in communication with one signal. Each of the signals indicates to a user that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination. A rotary lock includes a dial which rotates a drive cam, which in turn rotates several wheels to their unlocking positions. One magnet for each wheel is provided on the drive cam. Each magnet communicates with one sensor provided on a master key, which also includes signals, indicating that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination.
