Anyone try the activity key? Have a neighbor take us out today and he couldn’t wait to show us the activity key.... but he’s not a big reader of manuals: etc. He spent about 2 minutes waving, pressing and holding the band over and on the R on the tailgate before the car locked. Is that how it’s suppose to work? Anyone know? He then realized he left his phone in the car and couldn’t get it open. So we just left it.
