A friend of mine has a relation (uncle?) that was part of the litigation team that spent startling amounts of time trying to block third party accessories from being able to interoperate with Chamberlain openers, because of their proprietary "encryption" routine. But their encryption was startlingly simple, IIRC something like basically being one of 3 effective codes.
