I've found that my key fob is almost useless for opening my trunk. I have to actually walk away from the trunk toward the front of the car to get it to unlock. I can't figure out any use for that extra button except activating the homelink (because I'm inside the car when I activate it.) The other buttons are useless for locking the car if I'm more than a few feet from the back of the car (the usual direction I'm walking as I leave the vehicle in a lot). I have to get used to standing beside the car to lock it. With my G-Wagon I can walk halfway across the lot and remember to lock the car from there, and it works every time. I can also use my key fob to find the car at the airport if I've been away for a week. Because of the battery issues and trunk space I probably won't be leaving the Tesla at the airport lot, but still, there always comes that time when you walk into a giant lot full of cars and wonder just exactly where you parked, right? The Tesla's extremely short range makes it almost impossible to use the key fob to find the car. One more complaint... why are the buttons so darned hard to push? I actually have to hurt my finger to push the buttons sometimes, especially the third one, which is ridiculously hard to push. Combine that with the distance issue, and every time I look at the fob I shake my head in disappointment.
