Locking Lug Nuts
If your Mazda 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 storage, storage box, or
trunk. Register the key and lug nuts
with the lock manufacturer by filling
out the registration card and mailing it
in using the accompanying envelope. If
the key is lost, consult an Authorized
Mazda Dealer or use the lock
manufacturer’s order form to order a
new key.
Antitheft wheel lug nuts cannot be
installed on a steel wheel spare tire.
When installing a temporary spare tire,
use one of the original lug nuts in place
of the locking lug nut. The original lug
nuts are stored inside your Mazda.
