5.1 Keyfob
The keyfob primarily operates in the Off mode to reduce current consumption. Pressing a button initiates a wake-up along with a KeeLoq package transmission.
The two buttons SW1 and SW2 are currently configured for package transmission, reflected in the function code of the KeeLoq package. To transmit a seed package for pairing, press the buttons SW1 and SW2 at the same time.
