07 Impala LS keyless remote problems
I have a 2007 Impala LS, 3.5 w/55K on it that I just got. Great car with one exception. You lock the car with the remotes and when you come back later (15 minutes+), nothing! After manually unlocking the door and opening it (interior lights on) then the remotes work again. While they're working the range is easily 150 feet+ so the receiver/antenna appears to be good. My thinking is something in the pcm is "going to sleep" and killing power to the keyless system and staying that way until the door opening applies power. Since I'm not real GM literate yet I'm not sure where to look and I really don't want the dealer to charge me an $80.00 diagnostic fee just yet. Any help greatly appreciated.
