双向信号放大器， 放大汽车和钥匙的信号， 让车以为钥匙在车边.

我见过最搞笑的是买了宜家一种类似俄罗斯套娃的3层金属盒，把车钥匙放在最里面那个小盒子里， 实测屏蔽信号效果超一流.

What is Relay Theft?- F/ o- Y) T: x
, Z- B4 I6 j9 c1 o- O& q, c/ mRelay 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.9 {. O4 B/ ^4 k
: ?+ k0 P; Z* _' j! n2 xOperating 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 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.
