GMC Sierra Ignition Switch

The Ignition Switch of GMC Sierra vehicles performs the purpose of an ignition and charging system in the car and it starts the car engine and allows the car to operate. It triggers different electrical circuits, particularly the starter solenoid and other sparking parts, in addition to fancy gadgets such as the radio and power window. While older Sierra models came equipped with a mechanical key that needed to be inserted and turned to start the vehicle, the newer models have come with push start button and the vehicles are equipped with immobilizers. It seems that even to this day, ignition switches have not become much more complex and remain quite replaceable compared to their basic structure and function and are, in fact, even model-specific to GMC Sierra vehicles.

Each OEM GMC Sierra Ignition Switch we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
