If Trouble Arises
If your Toyota is equipped with the optional antitheft wheel lug nuts, a
special key must be used to unlock the locking lug nut for each  wheel.
The  key  is  stored  in  the  glove  compartment,  center  console  stor age,
storage box, or trunk. Register the key and lug nuts with the l ock man-
ufacturer by filling out  the  r egistration card and mailing it  i n using the
accompanying envelope. If the ke y is lost, consult your Toyota dealer
or use the lock manufacturer’s order form to order a new key. A ntitheft
wheel  lug  nuts  cannot  be  installed  on  a  steel  wheel  spare  tire.  When
