not normal. most likely a faulty fob altho could be problem with bcm but you would probably have other issues in that case. 99% of all remote entry problems are a faulty fob and more than half of those are the battery. weak signal do to the battery would be my guess.

Well, the thing is Ive put new batteries in both fobs and if my car sits for a few days I have to resynch the fob to the car? The manual says the fob receiver should keep track of the changing code but I always have to hold both buttons down and resynch. Its done this for a few years, I thought it was normal until my friend that has a corvette wondered why I did it one day, and he told me his didnt do that. Maybe my receiver Is bad??? anybod else have this happen?

well sounds like you have eleminated the fob or fobs rather. i would take it into your local dealer and have it diagnosed before guessing and replacing any parts. there are basicly only 2 other parts in the system, recever & bcm. it would seem the bcm has a problem remimbering the signal altho i would exspect there to be other problems with the car if the bcm were having issues but too much to guess at, average dealer only charges 1/2 hour labor for diag $40 in most cases. sorry i can't be more helpful.

I agree with the first part of this statement...only if it`s one Fob not both having to be retrained.
The BCM has nothing to do with the FOB Issue...The RKE (Remote Keyless Entry)Module would more than likely be suspect.

did some research on this today and the rke module is the most suspect as it is were the signal is stored not the bcm. i replaced one on a 97 C5 about 5 years ago, i can't remimber the exact loc but seems like it was inside the car under the interrior, drivers side, rear of the drivers seat. wish i could be more help.
