Buy GMC Jimmy Ignition Lock Cylinders

The ignition lock cylinder is a crucial component in your GMC Jimmy's ignition system. It's the part where you insert your key to start the engine. Located in the steering column, it works in tandem with the ignition switch to power up your vehicle. When you turn the key, the cylinder activates the ignition switch, which then sends power to the starter motor and other essential systems. (RepairPal.com, CarParts)
