Last June I picked up an '04 GX, and drove it regularly until late August. Had a family issue and had to travel up to WA for a number of weeks, and then was back and forth for most of the last few months. Last time I drove the GX was in the first week of December. When I got back a week ago, I found the battery completely flat. Purchased a new one a couple of days ago, and then went to put it in today. As soon as I put the 2nd terminal on, the horn started honking and lights flashing. Doors locked. I have tried a few different combinations of key-presses on the fob (lock, unlock, then relock, etc...) and nothing works until I remove the battery cable. I am guesstimating the battery has been dead for at least a month, but don't know for sure. Has anyone else experienced this sort of thing and have any tips? I did order a new battery for the fob, just in case it is low/dead as well. Won't have it until Tuesday tho. If there is a trick or anything else I am missing, sure would like to know! Want to drive this again!
