My 2006 Chevy Malibu key fob just got programmed by the dealer and then it stopped working a month later. I went to the auto parts store and bought another battery cause my car said "fob battery low". So I had the sales guy do it but it only worked a day. What exact battery does it take? The auto parts guy also said that the battery was loose and it would need to be soldered on the back to keep it in place.

I just had to fix the same problem. Some of these fobs didn't get the battery holder soldered on very well when they were made & the battery holder can come loose just by dropping the fob on a hard surface. Of course if this happens the fob becomes intermittent. The good news is that any competent electronic shop or hobbyist can easily re-solder it back into place. However it is possible to set the holder too deep in the holes & if you do the battery may not fit. So install the battery before you leave the shop.

My chevy malibu(2006) keeps stopping on me as if I turn the key off. I sit for a minute or two and it starts right up and runs fine. The panel lights don't come at this time..it just dies. Have replaced ignition mod. & put in new thermostat, better grade gas but it still stops. Any ideas?
