Question about 2008 Chevrolet Impala
When the temperature drops below around 40 degrees, the keyless entry and remote start won't work - unless I'm just a couple of feet from the car. Same result with second remote. Dealer reprogrammed remotes - same issue. Checked batteries on remotes. They are fine. Doubt it's a remote problem, because they weren't exposed to the cold - only the vehicle. Even on warm days, distance is not great. But it works while I'm still in the house.

i had the same problem... go through the menu until you see reprogram remote. hit the check mark button and hold the lock and unlock button until the horn honks. key has to be on car not running though. You will eventually have to do it again but for some reason it will work for a while.

KEY FOBS FOR THIS MODEL MUST BE PROGRAMED USING A TECH 2 SCAN TOOL SO IT MUST BE DONE AT THE DEALERSHIP FOR ABOUT HALF HOUR LABOR HOPE THIS HELPS

I HAD THE SAME PROBLEM, CHANGED OUT BATTERIES IN MY REMOTES AND HAD THEM TESTED AND THEY WORKED FINE. THEY DEALERSHIP STATED IT WAS NOT UNDER WARANTY AND IT WOULD COST $600 TO FIX IT. YOU CAN ONLY REPLACE IT THRU A CHEVY DEALERSHIP. KIND OF A SCAM!
