Vehicle door latch with double lock function

A method of double locking a vehicle latch, the method comprising:

• disengaging an outside release lever of the vehicle latch from a pawl of the vehicle latch with a first locking mechanism, the first locking mechanism includes a motor for driving a worm that rotates a gear;
• and
• disengaging an inside release lever from the pawl of the vehicle latch with a double lock mechanism such that when the double lock mechanism is actuated into a locked state, movement of the inside release lever will not release the vehicle latch, the double lock mechanism includes a motor for driving a worm gear that meshingly engages a sector gear such that rotation of the worm gear by the motor of the double lock mechanism will cause rotational movement of the sector gear, the double lock mechanism also includes a double lock link coupled to the sector gear at one end by a pin and operably coupled to a double lock lever at an opposite end, the double lock lever being rotationally mounted to a latch housing of the vehicle latch such that rotational movement of the sector gear will cause the rotational movement of the double lock lever, wherein the double lock mechanism also includes an over center spring having one end operably coupled to the sector gear and another end secured to an actuator housing of the vehicle latch, wherein the double lock mechanism also includes an over center spring having one end operably coupled to the sector gear and another end secured to an actuator housing of the vehicle latch,
• wherein the double lock mechanism also includes a manual release mechanism, the manual release mechanism having a key cylinder lever rotationally mounted to the latch housing of the vehicle latch and the key cylinder lever rotates about an axis that is the same as an axis of the rotational movement of the double lock lever.
