Steverino, I trust that you live in a place where people don't steal "portable homelinks" aka garage door openers. I live in a nice area, but there are reports in my neighborhood where they break into cars, steal the remotes and now have access to your garage and likely home. The best solution (that stays with the car) is homelink where it works only when car is on or a minute or so afterwards. Best solution outside of the car is app on phone that opens garage.
