i just had a new ecu installed and only one of my keys will start my car cuz the rest of them have not been learned by the ecu. how do i do this with out having to take it back into the dealer again? please pm me with this info.
thanks

 

I believe that you have to go back to the dealer. I had my ECU replaced and I had to bring all of my keys back to the dealer when I picked up the car. It should be free.

 

Yup, that is problem. The dealer has to reprogram the ECU. IF it wasn't for this, I would have changed to a 02 ECU awhile back. PITA!

 

Hi
The keys have to be programmed at the dealership level. This is because your car has an immobalizer system. The key does not really get learned to the ecu it gets issued to the immobalizer ring. If you could program it yourself then it would be that easy to steal your car. Take all your keys to the dealership and they will contact Honda USA or Honda Canada for what is best termed as a rolling code. This code is then entered into the PGMFI tester and then the learning process is put into each microchip in your key. This should not cost you anymore than .6 to 1 hour labour. Just don't loose a key as then they get expensive. Thanks---Westwood Honda Greg
