I thought this was such a great idea, I just had to share it. You know how most remote car door key pads have a "Panic Button." Most people get at least two remotes. Besides putting one on your key chain, keep one at the bedside or even on a chain around your neck. Then if you ever feel threatened or are in a situation where you can't reach a phone, you punch the panic button setting off the car alarm, which should scare away an intruder and/or get someone to come investigate.
Most car remotes reach quite a few feet away from the car, but test it in your house to make sure it works for you. If so, pretty cool, huh?
