Do your warning chimes and turn signal "clicker" produce noise?So now the question is, can the aftermarket radio effect the key fobs or is the remote door lock module 🧐 defective. 😫
Was the aftermarket radio installed when previous key fob did work somewhat?
If both yes, I would not suspect the aftermarket radio is the issue.
Did you check fuse in rear fuse box for RKE, which I think is #32?
@Dicktator I am sorry I meant no disrespect and realize you know how to program key fobs. I am just trying to help determine where the problem exists and simply stated that I don't think the installation of an aftermarket radio will prevent the programming of key fobs. I believe there is most likely another issue. Just trying to help determine how to find out what that could be.
You said that your tech2 would not talk to the ECM for key fob programming -- do you mean it would not communicate with the RCDLR (Remote Control Door Lock Control Receiver) also called RKE or do you mean the actual ECM?
You also said you could establish communication with the BCM, did you happen to check if there were any codes in the BCM?
I would expect to possibly see a code U1128 -- lost communication with radio. This could be due to the aftermarket radio.
But I was wondering if there was a code U1176 - lost communication with RCDLR ? This might indicate a faulty RKE receiver or a power or ground problem to this module.
