New ECM/PCM installed now immobilizer does not recognize remote start.

Question

this remote start has been functioning properly, but I had the ECM replaced by Honda and since then I can not remote start the car.  I have attemped the reprogram several times to the same result, the immobilzer key flashes on the instrument cluster and the car just cranks but will not start.  I tried it with the key in the ignition, hit the remote start and everything is as it should be.  A started and running car.  So, what is going on with the remote system?? thanks in advance for you assistance.

Answer 1

Definitely need to reprogram the bypass module and to first RESET the bypass module.
