content: It's more that this device beats the rolling signal/code key fobs they have been recently rolling out. But it's design would mean you would have to scout out a car and then wait for the owner and then hope they press it twice without using the key. Then after that you get one chance to open the door and do what? Steal the contents from the car? Criminals don't give a shit about this... If it's in the car, smash window get item.
