Immobilizer System
The immobilizer system allows the
hybrid system to start only with a key

key requires security validation, this
will add some delays in supplying a
replacement key. They are only
available through an Authorized
Mazda Dealer.
Always keep a spare key in case one
is lost. If a key is lost, consult an
Authorized Mazda Dealeras soon as
possible.
If you lose a key, an Authorized
Mazda Dealer will reset the
electronic codes of your remaining
keys and immobilizer system. Bring
all the remaining keys to an
Authorized Mazda Dealerto reset.
