A lock including a device for unlocking the door of a motor vehicle in case of a malfunction of the lock, as in the event of an accident of the motor vehicle, to open the lock or allow the lock to be reliably opened manually.

Also included in the lock is a rotary latch for engaging a closure wedge upon a locking of the door, and a pawl which holds the latch in a locked position during normal locking of the door, but releasing the latch upon operation of the setting device in the event of a sensed malfunction.
