Keypads on the outside of the garage let the kids in after school and let a neighbour water the plants while you are away. Programming a new one, changing the number or replacing a weathered unit is quick work for us.

Garage Door Opener Diagnosis and Repair
Limits, force and the two safety tests
Finally the settings are checked against what the door actually does. Travel limits decide where the door stops at the top and how firmly it meets the floor; a limit set slightly long makes the door hit the slab, sense an obstruction and pop back open. Force settings decide how much resistance the opener tolerates before reversing, and these drift, or get turned up to hide a stiff door.
Both are read, the door is run through full cycles, and the contact reversal test with a 2x4 and the beam-interruption test are performed. Any setting that only passes because force is cranked high is treated as a symptom.
