4th Key won't start the car?
purchased a 02 Civic. One of the four keys will turn the engine over but will NOT start
car. The other three keys start car. Car runs fine. Doesn't appear to be a valet key as
those usually start car but do not allow access to trunk. What's up with this?
Maybe it was never programmed. A none programmed key will open the doors but not start the car.
Don't forget to take ALL OF YOUR KEYS if you go to have the 4th one programmed. Usually the dealer will need to reintroduce all keys when programming a new one.
either un programed like mentioned above or possibly that key doesnt have the immobolizer chip in it
