Yeah, there's plenty of threads hehe. You hold the far left and right buttons down until it blinks slow then fast(or just blinks?) - That will reset the programmed buttons. From there, you get the remote to the garage door you want to open and point it at the Homelink Visor Garage door opener thing and hold down the button stimuaneously with the garage door opener. The light on the visor will change from solid to blinking slow then fast. The button is programmed, hold it down and see if the garage operates. If it doesn't, your garage door has "rolling code" which means you have to locate the "learn" button on your garage door opener. Press the learn button. Run to car within 30 seconds and hold the button you programmed for 2 seconds, then release, then 2 seconds, release.. etc until the garage door light blinks or shows that it's recieved the signal. The button is now in sync with the opener, you hold it down and it operates the garage door(s) now.
