The Immobilizer System protects
your car from theft. A properly-
coded master or valet key must be
used in the ignition switch for the
engine to start. If an improperly-
coded key (or other device) is used,
the engine’s fuel system is disabled.
When you turn the ignition switch to
ON (II), the Immobilizer System
indicator should come on for a few
seconds, then go out. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to
LOCK (0), remove the key, reinsert
it, and turn the switch to ON (II)
again.
The system may not recognize your
key’s coding if another immobilizer
key or other metal object is near the
ignition switch when you insert the
key. To make sure the system
recognizes the key code:
Do not keep other immobilizer
keys on the same key ring.
Use a plastic or leather key fob,
not metal.
Keep other keys away from your
car’s key and the ignition switch
while trying to start the engine.
If the system repeatedly does not
recognize the coding of your key,
contact your Honda dealer.
The Immobilizer System indicator
will also blink several times when
you turn the ignition switch from ON
(II) to ACCESSORY (I) or LOCK (0).
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your car undriveable.
If you have lost your key and you
cannot start the engine, contact your
Honda dealer.
