I need the Manufacturer’s 64-bit code for this IC to program the decoder for HCS500-I/SM.
Welcome to the Tech Forum!
You can come up with any manufacturer’s 64-bit code you wish to program into the HCS500-I/SM KeeLoq decoder. It is not pre-programmed in by Microchip. As the manufacturer of the end product which uses the KeeLoq device, it is up to you create and program that code.
Just be careful to keep that number secret, or others can use it to hack your device.
