I'm having a hard time trying to resolve an immobilization problem with my 2010 Accord. I've had the car to 2 dealerships, contacted a friend who is a tech and he gave me a bunch of things to try....obviously no luck. The problem started when I put a new battery in. Changed the battery 3 times since I bought the car. No problems until this last time. Put the battery in, went to start the car. It ran for a second and shut off. Went to start it again and it wouldn't. The CEL (check engine light) came on. At that point, an image of the key started flashing. I pulled the key out of the ignition and waited. The key flashing stopped. I attempted to start the car. It fired right up and continued to run, but the CEL (check engine light) stayed on. This is the way I have to start the car. Three attempts and it finally starts. When the key stops flashing, the immobilization system is shut down; hence the vehicle starts. I was told it could be the chip inside the key FOB. Is that the battery in the FOB? The dealership told me to have new ones put in, which I did. Car started right up. No CEL. I went to start it about 3 hours later, same BS. HELP!!!
