2009 GMC 2500 Built In Garage Door Programing

[hoppe56307]

I am trying to program the built in garage door opener on my truck and I am not having any luck. When I bought the truck it did not come with an owners manual so I can not check that.

My garage door opener is a Liftmaster with a learn button, but it also has dip switches. So I am not sure what to do.

Thanks for the help.

Not sure if this will help as you don't say what your vehicle is.Here is what my owners manual says.Turn off the engine then erase factoty/earlier(?) codes by pressing the 2 outside buttons.Release the buttons when the lights in your overhead console begin to flash(~ 20 seconds).Pick the one you want to program & while holding your hand held remote 2"-5" push both buttons.The light will start to flash slowly,hold until light flashes rapidly(this may take 60 seconds).That is for a '99 Chrysler & a Chamberlain Whisper Quiet opener.

My bad.I forgot the title of your post.If what my owners manual doesn't work I would think you could do a Google seach & find it.

I have tried google, and youtube and have not been able to find a solution that works.

I provided you a link to the online version of the owners manual. Section 2 deals with programming the homelink. Did you follow those directions?
