Why won't this key on my laptop work?

I don't know if this is the right platform to ask for help on this but I'll try anyway.

So recently a sibling accidentally took off the "W" key from my laptop. I followed youtube tutorials on taking out the 2 plastic pieces that surround the rubbery circle below the key and I removed them without damaging them. After that I noticed there it was a little dirty under the key so I cleaned most of the dirt out. I carefully placed both plastics back inside and it made a click sound so I know I did it right. Finally I put the "W" key back on top and pressed down hoping it would be fixed. Now the key is stuck downwards. Usually a key is up and you're able to press it down so it registers, but in my case it's as if it's always being pressed down, as in the key isn't popping back up, but the key also isn't registering, so it's not constantly spamming "W". I don't know what to do. I can't use my "W" key because it's not popped upwards. Any help on this is appreciated.
