I just installed a new Liftmaster opener and had to reprogram both vehicles (2021 F150 and 2021 Prius). I made sure that I removed the old code from the vehicles BEFORE I reprogrammed the Homelink system (followed the recommended procedure in the vehicle manuals). Both vehicles were reprogrammed...
Gave my 2001 Tacoma to my granddaughter. Sold my 2003 BMW 530 and we're down to just a single vehicle-a 2021 Prius! Truck should be here anytime and i can't wait.
