What is Relay Theft?
9 P, D6 m: c, p+ A9 G C( [! w7 x T& K4 C# y( U6 S$ N0 c: H) d
Relay theft exploits a vulnerability in passive keyless entry systems, which allow drivers to open and start their cars without removing the keyless fob from their pocket.

Operating in pairs, one criminal holds a device up against the car door, amplifying the signal it broadcasts around the perimeter of the vehicle. Another stands near the front wall or porch of a home, with a device that relays the key’s signal back to his accomplice.

The door opens, and the signal is relayed a second time, starting the engine. Once started, the engine will not restart without the key present.3 B+ c; u7 i; X( ~, B0 X+ T
