If you're looking for the code hopping algorithms used by Microchip's "KeyLoq" systems, you'll have to go to Microchip to get them (legally). They'll require you to sign a non-disclosure agreement at the very least, but I sincerely doubt that they'd even tell you anyway unless you're representing a large corporate client. Details available in the public domain are scant. Ask your nearest Microchip folks for information. Rick Miller
