On models that have a liftgate lock cylinder that is built into the latch release actuator, the whole component cannot be replaced individually and it has to be replaced. The first thing to do is to open the liftgate and unplug the cable in the negative battery terminal and then remove the trim panel. In the case of a lock that fails, the liftgate may be manually unlocked using the emergency access lever that is located inside the car and possibly requires removal of a trim panel to access. Then, loosen up the wiring on the latch, strip it, and detach the latch out of the liftgate, and it is the same process when putting it back. Should it ever be necessary and may prevent access, then remove the tailgate wiper motor, followed by unloading the wiring of the handle/release unit. Take out the holding fasteners that hold the unit to the liftgate and locking brackets, then swing the unit clockwise to take it out and loose the drain hose (when present). Reinstatement is done in the same sequence as the removal is done keeping in mind to verify the functionality of the lock components before installing the trim panel once again. The liftgate support struts are taken off on all the models just like the hood support struts.
