Thanks for the respponse,,,,,I do have comfort access...however,,,sometimes when I insert the key into the slot,,,,magically the warning triangle goes away after driving it a few minutes....so that's was my assumption that it was recharging itself,,,,but then I looked in the book and it says to replace the battery with the battery that you quoted,,,,,I am really confused on this. Normally I would take it to the dealer to get it fixed,,but since I am about 1 1/2 hours away from the nearest dealer,,,I thought I would go this route first and see if anyone else had this issue. If the key fob just needs a battery,,,that should be a simple fix,,,BUT still kind of curious about the charging routine......Thanks!!!
