Don't garage doors use rotating keys, like car fobs?

There is alternative firmware that allows you to do some things with rolling codes. Most of the cool stuff the flipperzero can do can be found here - https://github.com/djsime1/awesome-flipperzero

Modern ones do, old ones do not

[lost_tourist]

yes they do

It depends on the garage door opener.

Sure but most use rolling codes. Y'all can downvote all you like, it's still true, and downvotes won't change that.

The parent's comment was reasonably stated, and you haven't challenged its factuality. Also, you don't know that they downvoted you.

Regardless, what you said implies that no more than a negligible amount of garage doors don't use rolling codes, since the reason for my question was security related. If that's not true, I therefore wouldn't say your comment was strictly true.

All this is to say, votes up or down aren't that important. The attitude seems unwarranted.
