Like two of the other posters I just use the remote keypad mounted on the outside of my garage door. My problem is that when I go out on my bike I never carry any keys with me and one day I came back from a ride and found out that there was a power outage so the door opener wouldn't work and I was stuck outside till the power came back on. Now I have a hide-a-key outside. (At least I hope it's still there, I guess I should check.)
