Understanding a Signal Repeater?

This second type of device takes a different approach. Instead of storing a transmission, it stretches the reach of a electronic key that is sitting somewhere nearby. The consequence is that a vehicle can be tricked into assuming the real key is present. Just like grabbers or attrezzatura per codifica chiavi auto, such tools are used for the most part for illegal access.
