We actually watched a demo of how they steal cars and, now in the Holidays, all of your Christmas Gifts. They stand in the parking lot with a small 4x6" machine and as you walk away from your car and click your activator to lock your car it picks up the code. They walk over like they are opening your car door and click the machine and opens your door, someone drives up behind the car and they offload everything, get in and drive off. They showed us 5 different cars and it worked every time. They can buy the gadget for under $20.00 on the internet. Scary! I hand lock my doors now.
