Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will be glad to help you with your Acura questions today.
Is the green key light in the gauge cluster flashing while cranking the engine?
Ok that tells me that you have an immobilizer system that has failed.
Do you have another key to try?
The immobilizer system is a theft deterrent that will prevent the car from starting when the wrong key is used.
Each key has a code that the immobilizer control unit reads and then sends to the PCM. If the wrong key is inserted the PCM will allow the car to crank but not start.......this will also happen if the control unit has failed which is also fairly common.
The best advice I can give is to have it towed to the dealer so they can hook up the proper scan tool to determine if the key or control unit is bad.
The only other option would be to have a mobile locksmith come out and try to re-program the key to see if it will work. If it still does not work it likely will be the control unit that has failed.
Any other questions for me today?
It is very possible.
If the chip inside the key get's any type of damage it can cause the code to not be read properly.
