My key fob buttons do not work for my 2013 Volvo S60; the key continues to work and is read when placed for the push-to-start function. However, none of the buttons work for the alarm, unlocking or locking the doors. I had a locksmith provide me with a new fob which also works for the push-to-start, but unfortunately, the buttons still don't work even on the new fob. I can no longer lock my car with the fob. Any suggestions?
