When the key light comes on it means your transponder key is not being recognized. If you have a second key try that and if that does not work it could be the immobilizer unit on the steering column.

alright started out by changing out my main body ground and tried that since I finally got time to work on it. and I haven't had an issue since im going to go through and change out all the grounds and put a better wire in though im still having issues with it though no alarm and not keeping track of fuel mileage.
