Hi, I'm new to the forum. I have a 05 350Z and my battery went flat due to a lot of short trips and the cold weather period. I took out the battery and charged it up and the car starts fine. The problem is that the key fob doesn't lock or unlock the doors now. When I put the key in the door lock and turn it, it will lock and unlock the car OK, but nothing happens from the key fob. It's seems that something needs to be reset. Has anyone got the answer to my problem? Thanks in anticipation. Keith.
