improperly-coded key (or other
device) is used, the engine will not
start.
When you turn the ignition switch to

again.The system may not recognize your
key’s coding if another immobilizer
key or other metal object (i.e. key

you insert the key.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle undriveable.
If you have lost your key and you

dealer. If the system repeatedly does not
recognize the coding of your key,
