Well I got a different output with lf search -u.
This is from the receiver with no fob in range:

I couldn’t get the fob to work so I put it on the proxmark and got slowly closer to the receiver. That didn’t work so I was going to quit, but I put it down on the couch again and as soon as I picked up the fob it got the same feedback as the door and the door opened.
So then I tried another test, I hovered the fob above the proxmark and then just moved it slightly toward the door and then I got this:
