How do you program a 2005 Honda odyssey to the garage door opener?

To program a 2005 Honda Odyssey to your garage door opener, first ensure the vehicle is parked outside, away from the garage door. Press and hold the two outer buttons on the HomeLink system (located on the overhead console) until the indicator light begins to flash. Next, hold the garage door remote close to the HomeLink buttons and press the button you wish to program while also pressing the remote button until the HomeLink light changes from a slow blink to a rapid blink. Finally, test the programmed button to confirm that it operates the garage door.
