If you have the anti-theft locking spoked wheel cover, each wheel cover has a lock bolt behind the center hub ornament. You need a special key wrench (stored in the glove box) to pry this ornament off and to remove the lock bolt. Do not lose this wrench or you will not be able to remove the wheel cover. The key wrench has a registration number attached to it. Keep the registration number in a safe place. Complete the registration card and return it to the manufacturer as soon as you buy the vehicle. To replace the key wrench, send the I.D. card to the manufacturer.
