Reading this thread I'm asking myself why you wouldn't just buy an extra battery and leave it in the glove box. It won't help with the situation with the 4 legged friend but if you can use the emergency key to get in, which you can still make a spare of them I think, that would allow you access to the battery in the glove box. You would still retain the FOB with you and the emergency key also. Losing them is a different story altogether though and thats just the breaks of some of us being forgetful since all this new technology evolved and became overhelpful.
