NOTICE: Replacement keys for ACS ignition switches should be ordered from Aircraft Spruce. Using non OEM keys or key blanks can create an unsafe condition and may void the FAA approval and warranty for the ACS ignition switch.  Check for key wear by verifying the key can only be removed when in the “OFF” position.
