/ Z, ?* Z$ l1 s$ i6 T) G0 r, O
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.1 Y( m4 A7 t: I# I
, q' B# Q' n. H4 |2 c" F
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.7 b3 w. H, z1 y1 p
" c" R. T( L5 M NThe 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.4 p( ~ b( n7 o& }; k* M& X/ C& ^
