Here's what finally worked for me to reattach my 2016 Macbook space bar after removing it to clean: https://www.youtube.com/watch?v=qCrF9Cdn.... You basically cut the white lever in half lengthwise and then reattach just half of it to the key and keyboard. (The half that has the non-symmetrical holes attaches to the single pins side of the key.)
My space bar was sticky but not stuck, and I tried to reattach it for over 3 hours using josephpgrendon's directions, but could never get the lever to stick to the keyboard, even though all the little pegs were intact. I thought it clicked into place several times and put the black key on top, but that just made the black key and the white lever connect; the assembly wouldn't attach to the keyboard.
I didn't really want to cut the intact lever but I definitely didn't have time for the ~3 hour visit to the Apple store, so I did it. Now it works better than it did before I cleaned the key, but not at 100% - the space bar still occasionally misses when I don't hit it square.

You need to separate the white part of the key from the top of the key, the part that's anchored by the 2 long wires VERY CAREFULLY, then press the white part into the base by the little pegs. Then you press the black top onto the wires bottom side (one sided peg instead of two) first. You need to keep track of the orientation of the parts and be VERY CAREFUL when you remove the parts because the little pegs break easily.

Do you know how can I buy a new spacebar? I broke some of the small pegs.

I found this website but can't figure out which space bar I need to order. I have a mid-2015 MacBook Pro 15" Retina https://www.replacementlaptopkeys.com/ap...
