Program garage door opener in 2005 rx 330

There are 3 programmable Homelink buttons you can use for different remotes. Just to the right of the buttons there is an indicator light.

Decide which button you want to program. Point the none battery end of your remote 1"-3" away from the Homelink panel and press both the remote and desired Homelink button down and hold them down at the same time. After about 20 seconds, the Homelink indicator light will change from a slow flashing to a rapid flashing. You can then release both buttons,
If the garage door responds to the Homelink, your done! If not, your garage door uses a rolling codes transmitter and must be trained.
Find the training button on your garage door opener's transmitter (usually mounted on the ceiling). Press the training button and within 30 seconds press and release the programmed Homelink button twice. If the garage door opener operates, you're done! If not, press and release the Homelink button a third time and the garage door should respond. If it still does not, you may have a very old garage door opener with a none digital transmitter (like I did). In that case, you either need to buy a new opener or try to replace the transmitter with a modern digital unit (as I did). Advantage: cheaper than a whole new garage door opener.
Disadvantage: The newer openers incorporate safety features that my old opener does not have.
