I don't know if openers are different in the UK, but I have two rolling-code garage door openers and I didn't have any problem programming my SLK. The manual told me how to do it. Basically, after doing the normal programming step I had to climb a latter in the garage and press the learning button on the opener. Then I had 30 seconds to get back in the car and press the appropriate button for a couple seconds. It has worked fine, since.
