Stop using your kill switch, it was not made for that. Use your key. I am not even sure if my kill switch works. I don't remember ever using it.
What happens when you forget to use the kill switch with the device? (dead battery}
For me, that is a lot of money for a gadget but it would be cool to have if it also had a proximity alarm that called your dog tag.

For the money
This one looks good.
