How do you change your garage code number when the keypad has only numbers 0-9 and start/stop buttons?

Question

It has numbers 0-9 and a large stop/start button and the previous owner doesn't know how and doesnt have the manual. Please help to keep unwanted people out of my garage!!!!!

Answer 1

There should be small switches in the door opener motor and the same in the remote.  Open both of these, look for switches and make the change to both of them to that they read the same.

Answer 2

It depends on the maker of the opener. The link below will work on Genie models and Sears models (scroll down for Sears/chamberlain). Those are the most popular

Ooops, forgot the link (sorry)

Answer 3

There is a button on the motor unit that  you have to press to change the code.
