OTHER BENEFITS AND ASSISTANCE
Keeping the Key Safe
Replacing a Smart Key may be costly.
We advise you to keep a spare Smart
Key and the key-number plate in a
safe place. If you record the key num-
ber in more than one place, do not
record it in a way that can be easily
identified and associated with the
vehicle. For example, don't leave the
number somewhere that can be
accessed by a valet. It is wise to keep
a copy of the key number outside of
the vehicle.
