    Lock-Ignition (Cylinder and Keys)

    Inspect/Replace

    • Make sure the engine only runs when the key is in the "on" position. If the key turns while in the off position, replace the ignition lock.
    • Make sure the ignition lock is securely attached to the steering column. If it is loose or wobbly, it should be replaced.
