A friend of mine had had his truck stolen recently while on a business trip to Dallas. He parked his truck in the parking area of the motel where he was staying. When he came out the next morning, his truck was gone. Obviously stolen. Here’s what the police told him probably happened.

One of the thieves stays close to the vehicle to be stolen with an electronic device that connects to the electronic ignition system. The other thief –armed with a different electronic gizmo– walks up and down the hallways of the hotel, sending out a signal that connects to the electronic key fob of the truck. A signal is then sent to the device in the parking lot, unlocking the truck and starting the ignition. It’s called a “relay attack” and here’s some video of a car being stolen from the owner’s driveway.

The key was probably on a table near the front door so the thief didn’t have to get any closer than the front porch.

My friend asked the investigating officer what could be done to prevent this kind of theft and was told his best bet was a Faraday pouch. Amazon has hundreds of them.
