Loose your car?

When you can't find your car in a parking lot, pressing the lock button a few times will generally make it beep and honk so you can track it down quickly—but this only works if your car is in range. Putting the keyless entry remote in your mouth and pressing the lock button can help extend the range. I also heard that you just need to put it under your chin and it works because the signal resonates in your skull.
