attached to the key set; detach this plate
and store it in a safe place (not in the
vehicle) for use if you need to make a
replacement key (auxiliary key).
Also write down the code number and
keep it in a separate safe and convenient
place, but not in the vehicle.
If your key (auxiliary key) is lost, consult
your Authorized Mazda Dealer and have
your code number ready.

The driver must carry the key to ensure the

system functions properly.
