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 stored with the spare tire.
- To allow vehicle service in the event the key has been misplaced, a Rotunda Master Service Tool Set 501-F004 (164-R3104) 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. It the key is on an angle, it may damage the key and the anti-theft hJ9 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.
