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.

Another stands near the front wall or porch of a home, with a device that relays the key’s signal back to his accomplice.1 l4 g' q( Y3 o. x1 k& Z" Z

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.$ {8 F! X1 b1 o% C; e4 L
