Does anyone know which garage door openers work with the Garage door opener in my 99 300m. I am looking at used and want one that will work, so I don't have to go out and buy new openers.

You just need to know if you have a older type fixed code, or the newer rolling code type opener. If fixed just press one of the three buttons and hold it while holding down the opener button, the lights on the over head button should start to flash quicker then it is ready to go. If you have the rolling code then press the train button on your overhead garage door opener and press one of the buttons (you will see Training #1, 2 or 3 depending on button chosen) the lights will flash faster then go out, you will need to probably do this 3 times before it stores the rolling code. (it is a pain but once done it is great)..
