Question Reinstall spacebar key of HP 15-ac040 laptop

[light0s]

Hello
I removed my keyboard keys to clean underneath it. Then I reinstalled all of them successfully but that spacebar key is really strange, it has four metal rods instead of the usual two metal rods!
I tried to install it many times, but there are two things:
1. When moving my finger across the spacebar key horizontally, I feel the metal inside, specifically in those two parts of the key (see third image).
2. The key doesn't work when from sides, I have to push it from the middle so that it makes a space.

Is there any advice?
Thanks.

Do the open ends of those U shaped metal rods not hook into whatever is in the base of the key on the laptop? It looks like they should slide into the raised metal parts there where you have the two arrows. The service manual doesn't seem to show anything on the individual removal unfortunately.

What I did is I attached the two U parts into the key itself and also one of the big metal rode as seen in the image below.
Then I push the key down to install it into the keyboard, but I get the same result and the key doesn't installed correctly.

So after reading your replay and watching the video mentioned by @helpstar , I made sure to slide the part (1) to (2) and slide the part (3) to (4), then install or push down the key, and finally the part (5) and (6) slid correctly into the other raised metal parts in the other end. While previously I just press down the key thinking the two end of the two U parts would slide by themselves. I just needed to slide one end for each U part and the other end will slide by itself in the pressing down the key process.

Thank you all. I appreciate your efforts.
