[QUOTE=black 04 zo6;1602665984]I got Richard on the phone!!! Apparently GM needs someone who can build a BCM that works. I installed the LMC5 correctly and plugged in the brown wire BUT I did not cut the other brown wire that loops back into the LMC5. Apparently the BCMs are different on C5s so there isn't ONE fix. For the '04 the brown wire needs to be inserted and the other brown wire that loops back in to the LMC5 needs to be cut. According to Richard everyone buying the LMC5 for their C5 shouldn't do the brown wire thing because it can cause more problems. So if you are having the "pull the key the key for10 seconds" (don't believe the message, it doesn't take 10 seconds), buy the LMC5 and follow the directions CAREFULLY. If you still have a problem call Richard 855 565 8388. May Richard live forever or at least another 30 years.[/Q FIXED?
