The Ignition Lock Cylinder is particular for Chevrolet Tahoe car models and it is involved in the ignition system of the car as a primary component of the lock and start up system. Operated with a unique key, it typically functions in four positions: engaging the steering wheel security, controlling power part, priming the fuel system and cranking of the engine. The internal electric contacts of the Ignition Lock Cylinder wear out over time and may prove challenging for key operation or failing to start the vehicle. If problems appear with the key insertion and removal and with turning the key, the lock cylinder may need to be replaced. The general construction and working principles of the Ignition Lock Cylinder do not have many variations depending on the type of Tahoe, despite the lock cylinder design targeting both security and function.
