Older model Genie garage door openers use dip switches rather than a "smart" to program the opener and remote controls. Unlike their Intellicode system, which you can program with a press of a button, the remotes and the door opener dip switches must match in order for the remotes to work correctly. You will need Genie's GT912 remote control to program the old Genie door opener to the remote. You can purchase Genie remotes at Sears or through Genie authorized dealers.
Get the three digit frequency number off your Genie door opener. The frequency number will be stamped on the rear of the motor. Purchase a GT912 remote control that uses the same frequency number as your opener.
Place a stepladder under the rear of the Genie garage door opener motor head. Locate the dip switches on the back of the motor head. There will be a line of nine or 12 white dip switches on the upper right corner.
Slide the battery cover off the GT916 remote control. Press where the arrow is by the cover with your thumb to slide the cover off the remote control. Locate the mode switch on the right side of the remote control dip switches. Slide the mode switch to either 9 or 12 depending upon how many dip switches the Genie opener uses.
Slide each individual switch on the remote control to the exact position each switch is on the door opener with your finger. Place the battery cover back on the remote control and press the white button on the remote control. If the Genie door opener does not operate, one or more of the dip switches is not set correctly. Remove the battery cover and review the dip switches and correct the ones that are out of place.
