Remote start not working

is there any check engine light on??
well about GMC and chevrolet i can say that if there is any problem with the engine/the engine light is ON then the vehicle wont start, just an idea that may be there is the same reason with your car.

Used parts such as starters and altinators don't last. It might **** but it sounds like you need to buy a new starter,altinator, and battery. Or just start with buying one at a time.

I have the same problem with my 2008 Grand Prix - replaced the batteries in both key fobs - they worked for a few days and quit working. Remote start does not work and both of the cigarette lighter chargers do not work either. I have recieved a "charging system failure" message on the readout screen as well. I have checked with 2 different mechanics and they are not sure what it is. Any help would be appreciated. Thanks!

check tps sensor check idle air control valve or iacv for proper func

and you tried both keys and remotes. If so then you will need the dealer if neither remote works.

If it is a GM factory remote starter try double clicking on the lock button first and then click the start button.

Good luck hope it works for you.

Have you found out what was going on? My car just started doing it as well.

To get the remote start going again, I remembered a time when my Explorer phob would not open the doors automatically, I was told to insert the key and toggle it from off to "run" (not starting it, but having the radio and lights come on) position about 4 - 5 times to reset it. I tried that with the car, and it worked!!

Thanks,

do you have the owner manuals .... it tells you how to program them for that car

I just had to replace mine and sounds like the same problem. At the local O'Reilly's they have a display that shows if the RF from the buttons are working, if you can find one of those. I tried cleaning under the pad and nothing worked I think this is a common problem from what the local dealer tells me. I had to push my old buttons harder and harder to get it to work until they did not any more. About $175 to replace and program at my local dealer.
