Just picked up this 2011 today. Remote seemed to work fine this morning as well as the door lock. Tonight when I try to unlock it with the remote, the lights flash 3 times but none of the locks do anything. Same thing happens if I press the other two buttons. 3 flashes. Battery in the remote bad? It works from 50 feet away. Wouldn't be too bad if I could at least open the door with the key but the blade won't all the way in all of a sudden.
