我现在是用faraday case钥匙包装钥匙， 回家把车钥匙扔那种铁皮的饼干盒里。

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 [1 @* L: O" \; |8 n
3 J( K, }1 b* B6 uOperating 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.3 R9 k* f* d1 j

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.- c& G7 w) f, ^ j
