A one-way RKE requires a manual button press to perform an action. The vehicle receives the signal and confirms that it is a valid code, then performs the required action. WebOOK stands for On Off Keying. OOK is modified version of ASK modulation. While in ASK modulation logic-0 is represented by lower amplitude and logic-1 is represented by higher amplitude; in OOK modulation there is no carrier during the transmission of logic zero. The carrier is transmitted during the transmission of logic one.
