At least with Garage Door Openers (GDOs). From the court's opinion granting Skylink's Motion for Partial Summary Judgment on Chamberlain's DMCA Claim:
BIPlog has brought this up before. This is the case where Skylink made a third party garage door opening transmitter (you know, the little dark gray plastic thingy with a button that you keep in your car) that worked with Chamberlain's garage door opener (GDO, and it's the mechanism in your garage that actually moves the door open), after which Chamberlain asserted this violated the DMCA. Chamberlain uses a rolling code mechanism (meant to deter thieves) to make their GDO work with their own garage door-opening transmitter. Skylink makes many different transmitters that work with several manufacturers' GDOs. In this case Chamberlain said that Skylink's accessing of the rolling code was in violation of the DMCA anti-circumvention provisions.
