Legal warning: Transmitting remote keyless entry signals to vehicles you do not own is illegal in most jurisdictions and may constitute attempted vehicle theft or unlawful interference with a radio device. Use only on your own vehicle for testing and research purposes.

Key fob TX transmits fixed-code remote keyless entry (RKE) signals for compatible vehicle remotes. Currently only Subaru is supported. The transmitted frame is a fixed OOK-encoded signal — it does not use rolling codes (KeeLoq). It is transmitted 4 times in sequence at 433.920 MHz.
