I replaced the a/c controller and now my van won't start, the immobilizer light flashes when I try to start it.

it needs to get towed to the dealer. they need to use the hds tool to program the key to the immobilizer...

there is no pass key on an oddysey,you must have replaced the ecu ,the immobilizer system has to be reset by the dealer as honda uses a rolling code that changes every hour ,bring all keys you want learned into the computer,hope this`was helpful,good luck
