I recently purchased a new control unit for a 2001 honda civic ex 5 speed. I took my old control unit out and replaced it with another. Now it won't even start. I was wondering how you reprogram the new control unit? if anyone has any information regarding my question, please let me know! thanks a lot

When you try to start it is there a green key light flashing on your dashboard?

dealer has to do it, and you need to tow the car there.

yes the green key is flashing. You have to take it to the dealer? do they use a special tool or computer to reprogram it? there isn't anyway you can do it yourself?

no you can't. have to go to dealer. there's a chip in the key.
