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.

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.0 w& k* B8 s0 A8 R1 t& m
0 @+ c3 R. ~. HOperating 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.2 J9 ^, o7 Y- F ?2 f) ~+ R

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.% f* S% o; t) E
