^ I tried to explain code hopping to him. I'm pretty sure his current unit has it. It's about 13 years old, has the safety eyes down by the floor. This guy makes bank - he's an editor, about half of his business is via Skype, but he can be clueless about the physical world. At one point the opener was stopping in mid flight and I couldn't make it right with the set buttons and dude is insisting that we need to spray WD40 at the point it's stopping. This after it effortlessly moved past that spot moments before. Something appears to be fried in its mini computer.

A few months ago, it phantom opened and closed several times and when he went to check it out, he said he saw a car make a K turn (he lives at the end of a culdesac) and take off. His anxiety was that the individual had hacked his code and was going to come back later. Probably just someone visiting a neighbor. I tried to explain the code hopping thing to minimal effect.
