all cars. did you try both key FOBS that came with car new?
that be first. if no spare, all may be lost.
same with all cars, what is the question.?
ill guess, is why is my system failing,
so im not looking up 04 masda, operators guide.
open your book and see , page, called how to start car.
ever seen that?
it tells you the meaning of each lamp on dash cluster.
one is security
other is Immobilzer.
that be first. the lamp that glows, wrong, is IT.
once that is found, then
ok here is your lost book,
btw, google 1st hit....... amazing, what google can find.
see page 72? Chapter 3)
real page 3-21, see that lamp. see how it works.
good and bad, is this IT.
here , ill quote it
If the engine doesn't
start with the correct
ignition key, and the security indicator
light keeps illuminating or flashing, the
system may have a malfunction. Consult
an Authorized Mazda Dealer.
(or any car locksmith, on earth)
