New key fob, 2011 CX-9
 

I recently lost my key fob and had a locksmith make a new key so that we could make it home from the airport. I already had an emergency key stashed that would allow me to access the vehicle, but it would not start it. The locksmith said that the emergency key had been poorly cut.

The key he made works well, but now the car beeps every time I open the door, and the universal fob I just bought will not unlock or lock the doors, but will start the vehicle.

How do I stop the beeping?
