Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. The remote may have failed. You can actually pull the plastic push start button out of the ignition and use the key to start it with no problem. That way you can drive it to the dealer to have the key checked out. Most certain the key is bad since you have replaced the battery. But again you can pull the push start button out of the ignition , it is nothing more than a plastic button. Then you can insert the key and start the car. The remote does not need batteries to start the car inside the ignition only to start with the push button. Hope this information helps let Me know if you have any issues. I am here to help. Lou.
