2008 Impala - keyless entry doesn't work in cold weather

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.

    2007 Pontiac G6 has the same problem. The remotes dont work at all in temps below 35F, work intermittantly 35 to 50. works fine in the 60s.

    Spoke with the dealer service rep and was told that there has been a service bullitin issued on these remotes, They are aware of the problem. Takeing the car in Tuesday 1/13/09 for new remotes. Hope that solves the problem,i'll post the result.

SOURCE: Remote start and door locks will only work from 10 feet or less

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.

SOURCE: remote starter does not work

I experienced this exact problem and found a note in the manual about fuel pressure problems if the gas cap is not properly inserted. I removed the fuel cap and reinserted it and the remote start worked fine since.

Ford 2008 F-350 remote starts great in warm weather will not start in cold. all lights glow plugs ect working just wont start truck and only if 35 degrees and below.


Since batteries lose almost half their cranking power at freezing, and since diesels require much higher fuel temps to start than gasoline engines, many recommend using a block heater whenever the temperature is under 35-40 degrees if starting becomes a problem.

What oil viscocity for honda accord DX 1990 for cold weather ?


5W- 30 is the lowest you can go in winter time. I would use a high mileage formula since we're talking about a 1990 honda. It will help condition the seals in the motor from making any oil leaks worse.
