[Brooklyn]

Yesterday I pulled over and got out of my car (idling) to grab my mail from the mailbox. When I came back to the car, turns out it had locked the doors on me with the key fob in my pocket. I had done this a hundred times before and if I'm not mistaken the car will not lock if the key fob is with you, yet it did. I suspect it has something to do with a low battery on the key fob.

[After searching the forums I read somewhere where someone had taken the valet key out of the fob and then trying to push the unlock button that way. I did this but in my haste I'm not sure if it actually worked, as at the same time I tried opening the trunk and it opened. I then proceeded to crawl through to get to the driver's seat. By the time I wiggled into the seat, the doors were unlocked...unless I just wasn't thinking clearly from having to contort my body in ways it shouldn't]

Anyone else have this happen? Or can anyone offer an explanation? Phantom signal? Car auto lock thinking the fob was still in the car?
