A liftgate lock actuato<\/a>r is a small electric motor and gear assembly that locks and unlocks your vehicle’s rear hatch when you press the key fob<\/a>, the interior switch, or the dashboard release. It sits inside the liftgate panel and drives the latch mechanism that secures the tailgate<\/a> to the body.
