4.3.4 Secure Key Generation

Use the seed word when pairing the transmitter to a receiver using a secure learn methodology.

To indicate a seed transmission, the encoder sets the serial number to 0xFFFFFFFF. The upper 64-bit of the 128-bit seed value is padded with 0x12121212.

The encryption/decryption key is generated similarly to the classic KeeLoq technology using the seed value and manufacturer’s code.
