What is an Ignition Lock Cylinder?

An Ignition Lock Cylinder is a mechanical component within the ignition system of a vehicle that allows the driver to start the engine using a key. The lock cylinder contains a series of tumblers that align with the key's unique cuts, enabling the cylinder to turn and engage the electrical components necessary to start the engine.

If you encounter any of these problems, consult a professional mechanic to diagnose and repair the issue.

Can a faulty Ignition Lock Cylinder cause damage to my vehicle?

A faulty Ignition Lock Cylinder can prevent your vehicle from starting or cause intermittent starting issues, which may strain the starter motor and other electrical components. Additionally, a worn or damaged cylinder can make your vehicle more susceptible to theft.
