BUT, because there is a but, and not a little: to over 2 m (and again, I'm nice) of the receiver, do not even try to press the buttons, it will not do that draining the batteries unnecessarily, the door will not open. The scope of this remote is really ridiculous.
What a pity if the remote had worked properly, it would have had my 5 stars. There, one star is enough: after all, it is a remote control in the first place, and it is clear that it does not give me satisfaction on this feature.
I hesitated before buying, but for the price I started, no luck!
So I carried on another remote control 433.92MHz (3x more expensive, yet still cheaper than the manufacturer's remote control), and it works. I could have avoided a purchase ...
