Review on Genie GM3T-R Intellicode 9/12 Dipswitch Garage Door Opener Remote (2 Pack) - Compatible With Openers Since 1993 by Andre Arias

I have an older Genie SD9000 garage door opener that I have been trying to find a remote for. Since it is an older model, it has been difficult. I didn't have a remote to get the correct code from for the 12 code dip switch, as the instructions stated, so I searched youtube and found a video which showed how easy it is to find on the garage door opener itself. Near where the light bulb goes, there is an opening that shows the position of the 12 switches. I simply matched them up to the switches on the remote, pressed the C button inside the remote by the switches and then chose one of the 3 buttons on the front of the remote to control the door. Voila! It worked!The remote is reasonably priced and was delivered in 2 days.
