Key fob quit working

[Mike E]

Last night I was out running some errands. Stopped at Blockbuster, got out, hit the key fob to lock the H3 and nothing. It was like I took the battery out of it. It wouldn't lock or unlock, panic button wouldn't work. So I had to lock it manually but when I opened the door it chimed once like I had the keys in the ignition. So I locked the doors and went into the store. Walked out of the store and it still would not work so I had to use the key to get into the H3. When I opened the door it chimed once again. I drove home, parked, got out and everything worked just fine again. Too wierd! Anyone else have this happen or have any thoughts? Thanks!
