Box Truck Auto-Lock Switch Accessory

This auto-lock accessory works with the box truck lock to automatically engage the deadbolt when the door shuts. It operated from a magnetic sensor and can be turned on or off from a switch. It plugs into the M2 circuit board and is very popular with the Box Truck Lock.

Note: This switch operates one M2 lock. To operate dual box truck locks from one auto-lock switch, you must purchase an M2 Control Switch for each M2 and merge the wires. One auto-lock will then operate dual box truck locks.
