Key information
Your vehicle is supplied with two coded keys. Only a coded key will
start your vehicle. Spare coded keys can be purchased from your
authorized Mazda dealership. Your dealership can program your key or
you can "do it yourself." Refer to Programming spare keys.
The SecuriLock passive anti-theft system is not compatible with
aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security
protection.
NOTE: Large metallic objects, electronic devices on the key chain that
can be used to purchase gasoline or similar items, or a second key on the
same key ring as the coded key may cause vehicle starting issues.
NOTE: If present, you need to keep these objects from touching the
coded key while starting the engine.
NOTE: These objects and devices cannot damage the coded key, but
can cause a momentary issue if they are too close to the key during
engine start.
NOTE: If a problem occurs, turn ignition OFF and restart the engine
with all other objects on the key ring held away from the ignition key.
Check to make sure the encoded ignition key is an approved Mazda
encoded ignition key.
If your keys are lost or stolen you will need to do the following:
Use your spare key to start the vehicle. or
Have your vehicle towed to an authorized Mazda dealership. . The key
codes will need to be erased from your vehicle and new key codes will
need to be re-coded.
Replacing coded key can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
WARNING: If an unprogrammed key is used in the ignition it
will cause a "no start" condition.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLock keys can be used. To program a coded key yourself, you
will need two previously programmed coded keys (keys that already
operate your vehicle's engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
