had a somewhat disagreeable tenant in the house we moved back into, and suspect the guy might still have a garage door opener for our house. our opener uses the genie 'rolling codes' system. I opened the transmitter, found no mini-switches in there to change (at least near the battery).
question: short of entirely replacing the entire opener, is it possible to change the "rolling codes batch" or "rolling codes groupings" that my wife and I use so that it's NOT the same "batch" of rolling codes it
-formerly- was? so that our old tenant can no longer USE any opener he may have? I'm 'pretty handy' with a soldering iron and tools, if need be...but not real great at 'board level repairs'...
thanks for tips and clues on this :-)
