2010 Subaru Forester; previous owner must have had two press unlock programmed as drivers door unlocks on first, and all others on the second. The problem is that the other doors unlock probably only 50% of the time, it's not easy getting the second press timed right. The dealer says it can't be programmed back as there was a period of a few years when Subaru didn't allow this. Any help please so I can program back to one press for all doors?
