I was trying to program a transmitter (and then use that to program homeland buttons in a car) to a VCRX, but I could not seem to get the VCRX to learn the buttons on Chamberlain universal garage door remote that I had in my car (the 953EV seen here: http://www.chamberlain.com/parts-and...ss-programming). Is it possible for the VCRX to learn buttons on third party transmitters or does it only work with the Lutron visor control transmitters?
