06 diesel 2500
 

I parked my truck, went in the store and when I came out cranks but no start. The entire engine only has 37000 miles on it since all new. Then I noticed that neither key fob will lock or unlock the doors? Any Ideas. I had no tools so I did not check the fuses yet. Of course I was 50 miles from home and 20 degrees outside.

It is possible the key lost its program. Or the truck went into security mode.
