Key cylinder : Key cylinders are used to receive toe key on an automobile. They are cut to a unique code pattern to help secure the vehicle. Key cylinders use tumblers to sense the key and will allow the lock to turn if the pattern is correct. Some key cylinders used on the ignition also house a sensor that helps determine whether or not the ignition housing or key cylinder has been breached.
