( l, s/ g6 V8 TOperating 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.# w" l* z4 X- R8 Q$ J( F+ D! T1 n

The car is effectively fooled into believing that the owner is within a defined range (usually two metres) and is approaching the car with their key. 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.( q4 ~$ Q8 `5 Y5 y7 t7 E9 Q: I
