Grandillusion

New to the forum... and in the same boat as the earlier poster... Purchased a used 2017 Hybrid Fusion - only one intelligent access remote. I've been searching the net and found numerous videos and pages telling how to program a remote if you still have the original two. This thread doesn't come right out and say it, but am I to assume (by this thread and the lack of any other info on the net) that programming a REPLACEMENT remote absolutely can't be done by an end-user (or did somebody discover a previously hidden/unadvertised process in the past 10 months)???
