I tried to use my spare key recently, and it just doesn't work to lock/unlock the car. If I unlock the car with my first key, then I can use the spare one to start the engine, etc, but it doesn't lock/unlock the doors, i.e. none of the buttons of the fob seem to be working.
I thought it was the battery, but I replaced that today, and still nothing. I tried to reprogram it (turn the ignition through 4 cycles until you hear a beep, then press the unlock button on the fob), but it doesn't respond to that either.
Any ideas? Is it just fried?
If it is fried, where can I get a replacement and how do I program it without having to pay wheeler dealer prices?
