There is no bettery in the key. There should be a resistor made into the key. The most common problem I find is the ignition lock cylinder. There is a small wire harness that comes out of the cylinder that usually ends up breaking at the cylinder. When this happens, the vehicle may or may not start. The security lamp will stay illuminated.
