I ran into issues programming mine too. I have the LiftMaster 8500 garage door openers. The first step was to program my truck by holding the button down on the visor and then push and hold the clicker button on the garage door clicker. Once the Homelink lights flash slow, then fast, your truck is programmed. Now go and push the learn button on your garage door opener. It might be on the motor or on the button panel on your wall. Push the learn button, then within 30 seconds push the desired button in your truck. You'll know if it worked because your garage door will open/close as soon as you push the button.
