My trunk will not open. For a while the key would't work and I could only use it by pressing the button inside, but now the bottom doesn't work either. Not sure what is causing this... Car Specs: 2005 Chevy Cobalt Regular, not an LT or LS No electric windows, locks, etc No cruise control

it is not a battery in our engine it is all the fuses i thought the same thing pull the black cover off and you will see there is only one battery and it is in the trunk

unfortunatly, that is usually a programming code that the dealer does not let out. that is one of there easy money makers. it cost me $180 at nissan to get mine done, because no one could help me there.

Are you using the original key that came with the car? The chip in that key may have gone bad. Try using the spare key that should have come with the purchase of the car. You may also be having battery issues. If all else fails....call the people who really know how to rape you...DUM Dum dummmmm....the dealer

make sure your battery connections are clean .. take the cables off the battery and clean them well. also trace the ground to see where it goes and see if it is tight ... If a battery tester or load tester is available test that battery while you are at it .. thanks Jerry and holler if you need more ..

There are only 2 things you can try to fix this yourself: turn off the engine and open the driver side door (to turn the radio off). Wait 5 minutes, start your car.
If that does not solve it, turn off your engine, disconnect the car battery, wait about 5 minutes. Reconnect the battery (negative pole first - black connector) and try your radio again.

If neither one of these two fix your problem, I am afraid only a GM service center or dealership can fix the problem. The Cobalt is notorious for all kinds of electrical issues.

Thanks for using the fixya forums!
