Raspberry Radio is a compact and power efficient car key fob relay. It is composed of two identical devices, one of which captures an unlock signal coming from a victim's key fob, then encodes and relays that signal to the second device which can then replay the signal to unlock any vehicle whose key fob operates on ASK (Amplitude Shift Keying) modulation.
