Anti-Theft

Optional chrome-plated wheels on vehicles are equipped with anti-theft lug nuts (one per wheel) that are installed during vehicle pre-delivery.
^ The key is attached to the wheel lug nut wrench, stowed with the spare tire.
^ To allow vehicle service in the event the key has been misplaced, a Rotunda Master Service Tool Set 501-F004 or equivalent is available at most Ford and Lincoln/Mercury dealer service departments. The lock manufacturer can be contacted at 1-800-669-8788 if a master key set is not available.
^ The key has a circular keyway that is matched to the female slot in the anti-theft lug nut. When locking wheels are reinstalled, torque to 115 - 142 Nm (85 - 104 ft. lbs.). DO NOT use a power impact wrench on the lug nut key.

Remove or install the anti-theft lug nut as follows:

CAUTION: Make sure the key is held square to the lug nut. If the key is on an angle, it may damage the key and the anti-theft lug nut. DO NOT use a power impact wrench on the wheel hub bolt nut key.

^ Insert the key into the slot of the lug nut.
^ Place the wheel lug nut wrench on the key.
^ While applying pressure on the key, remove or install the lug nut.
