My TSX has the same immobilizer as your accord. What sucks about this stuff is that you need the Honda Scanner to do tests.

Just by reading through the list of steps, you get to a point where the problem can be from the ECU, Immobilizer, a communication problem between the ECU/Immobilizer, or low battery voltage.

Is your car parked at the dealership or at your residence? If you can access your car, you may want to try jump starting it, or pull out the battery and having it tested at a parts store?

 

From what I was told there was a communication error between the ecu and imm. Also the battery was kinda dead so they had to charge it before they started working on the car. It's still parked at Honda, what do you suggest I do or what are my options?

 

I would pull out the battery and have it tested at a parts store.

I would probably replace the immobilizer myself.

If that doesn't fix it, then I would buy a used PCM and install that. The dealership would have to program the keys.

 

If I were to buy a used or new ECU, does honda have to reprogram it? If so what exactly would they reprogram besides the keys and how long should this take?

I would be able to replace both ECU and Imm, but the service tech made it seem like they have to use the HDS and input new data in the used or new ECU which takes long. I'm a bit skeptical.

If I have the car pushed or towed out of honda I would be able to replace the parts in probably minutes.

 

If you replace the immobilizer first, then you shouldn't have to reprogram the keys (unless the mechanic cleared the key data on your original ECU).

If you replace the ECU, then Honda has to reprogram the keys. It should take less than 30 min.

 

Thanks for clearing that up, being that they already have the car I think it'll be to much of a hassle to do the work myself. However I have to speak to the service tech and figure out why they want to charge $400 for labor to remove/install the ecu/imm and to program the keys. Sounds like this job should cost $110 for 1 hr labor or at the most $220 for 2 hrs labor.

They quoted me $622 for parts but I found it cheaper if I were to purchase the same parts online.
