    2007 sts 4 KEY FOB not working all the time.

    I have the car over 2 months and only came with the #1 key fob and this key fob has worked fine since then.

    Yesterday, it started not working everytime i tried to use the fob.The door locks and even starting the car doesn't happen everytime i try to use this key fob.The DIC had a CAN NOT DETECT KEY FOB but after a couple of attemps it did start up.

    I bought a new correct size battery yesterday and even with the new battery the key fob i still have the same problem as above.

    Is there something else i can try to correct this problem before going to the dealership?

    Try opening it and carefully try to bend up the little prongs. Possibly it's not making a connection. I had this problem. Had to put a little piece if paper under the battery so it makes a connection. Mine works fine now. Hope this helps!

    Have the car's battery load-tested. Is anything else in the same pocket as the fob?

    If you don't have a physical key, get one from the dealer or a locksmith ASAP. You should also get a second fob and match it to the car, it will help diagnose your issue but without a real key, you are taking a huge risk.

    One time recently I had my iPhone 5 and my fob in the same pocket and the car wouldn't open up. And that was just after reading about that on this forum. Took the phone out of my pocket and I was good.
