Do you have another key that can test this theory?
Thanks, I tried changing batteries to no avail (unless the batteries are cheap...bought them at a dollar store). Will try w/ the other key fob.

Btw, silly question: how do I know when my car's battery needs replacing? It doesn't have a 'status window' I had in my old car so I have no idea. Any warning signs before the car's battery dies?
