Ignition keys are used for the ignition switch. They may be sold separately or come with a new ignition switch. When buying a replacement ignition switch, ensure that you have the appropriate key. It is possible for ignition keys to wear, and they can lose their shape and become dull over time. Either lost or worn down, we always suggest replacement ignition keys from an OEM original parts dealer, like us, to ensure they fit exactly as intended for safe operation by the OEM.
