Universal garage door openers are programmed by following the included code sheet. The code sheet has a list of several garage door opener brands and model numbers.
Prior to purchasing the universal garage door remote, verify the brand and model number of the garage door opener are included, and that the frequencies of the opener and the universal remote match. Find the brand and model number that matches the garage door opener. Key that code into the remote and press enter. Test the garage door by pressing the button on the remote. If the code works, the garage door opens and closes on cue.
