Garage programming - rolling code
I'm pretty sure my garage door opener uses a rolling code. But the manual is confusing. It looks like you have to program with *BOTH* the remote control and the learning button on the garage door opener? Is that correct?

I think that it depends on your garage door opener. I have added my 2019 S450, and my wife 2022 GLS450 this year, and in both cases I didn't need to touch the learn button on the opener (first time ever!). But, I did have new openers installed last year....

Some of them have the learn button on the wired key pad so you don't necessary have to climb up there to press it but basically you press an unassigned button and then it will turn amber, then you just point the garage door opener at it and start pressing, keep pressing until it either stays green or flashes (if flashes then it has a rolling code), then you quickly go out and press the learn button and return to your vehicle. Keep pressing and holding the button you assigned until your garage door opener reacts.

Yes, if you garage door opener uses rolling codes then it's a two step process. First you use one of your old remotes to program it the button you want in the car. Once that is done, you need to press the learn button on the garage door opener so that the car and garage door opener can exchange the rolling code sequence. If you skip the second step it might work initially, but eventually the rolling codes will get out of sequence on one side.
However, there's also a new Homelink standard now that uses bidirectional communication. The programming sequence for one of those might be different if the car supports it. I don't have one of those. Programming a new car/remote for my Liftmaster always involves the two steps above.
You can also go here, specify your car and garage door opener and then follow the instructions.

Also, if it doesn't work at first, try the programming process *with your windows down*. I'm guessing that the emitter in the mirror unit is relatively weak, or maybe my garage door opener's receiver is insensitive, but it only works for me reliably if I roll at least one window down.

So for my gate openers they use a frequency that is not compatible with homelink on the car. The solution I found was to buy axillary receivers like this http://www.northshorecommercialdoor....YaAhEvEALw_wcB
They simply wire into the opener just as if you were wiring a push button switch for the garage door. Once that is done you use the remote that came with the receiver to program your car homelink.
