1998 Explorer uses a PATS II system with a transponder in the keyhead.
Locksmiths have transponder detectors that read if a transponder is active within a key. The device we have is called "TD3AII Transponder Detector" by Ilco.
if the pats transponder (the red bit) in the key is broken its a ford job, but if you have all the bits of the key hold them all right next to the ignition key hole and try to start the car before taking to ford. a friend had a worn key and had a non pats key cut, the new key wouldn't start it alone, but if he held both black bits of the new and old key together then tried, the car would start. I'm not sure if it will start if the transponder key is dangling on the same keyring, but give it a try. its cheaper than a new key from ford.

Normally it would only cause a problem if the transponder key had severe damage or trying to start the car without the transponder. If the key looks ok and there's no damage to the sstem then it's probably not the transponder system causing the problem. The dealership could figure this out.
