I just bought a used 2004 Honda Accord EX V6 and it didn't come with a manual, so I'm curious how I can program the garage door opener installed on the vehicle? Does anyone know? Thanks in advance.

I did as best I could to reproduce the instructions from the Accord Owners Manual. The system is called "Homelink" in the manual. there are two procedures to program the remote; the first works in 90% of the cases.To start, erase any stored codes-- press and hold the twooutside buttons on the HomeLinktransceiver for about 20 seconds,until the red indicator flashes.Release the buttons, then proceed as followsUnplug the garage door openermotor from the electrical outlet.Hold the end of the garage dooropener remote 2 to 5 inches fromHomeLink. Make sure you are notblocking your view of the redindicator in HomeLink. (the ignition for the car may have to be turned on; it doesn't say if it does or not)Press and hold the remotetransmitter button and one of theHomeLink buttons at the sametime. While continuing to hold theHomeLink button, press andrelease the remote transmitterbutton every 2 seconds.If the red indicator in HomeLinkbegins to flash slowly at first,then rapidly, release bothbuttons, Plug in the garage door openermotor, then test the HomeLinkbutton by pushing it for about 1second.If the button works,programming is complete.If the button does not work, youhave a rolling code transmitter: ‘‘Training with a RollingCode SystemFind the ‘‘training’’ button on yourgarage door opener unit.unit.
