I was getting a message to change the battery in my key fob. I changed it and then not only doesn't the fob I replaced the battery in not work neither does the spare. I used the key to open the door and the horn started beeping. I put the fob in the pocket and was able to start the car. When I took the fob out of the pocket it said no fob detected. I can't open the doors or lock them with the fob. Any suggestions? TY in advance.
