Caps Lock key on keyboard won't spring back up after removal

I was trimming my fingernails while watching YouTube when a small piece flew under my caps lock key. I tried using tweezers to get it out, but it slid underneath the key. I figured the best way to get it out was to remove the key so I did that. I used a tool to pry the bottom right corner and it popped off. However, when I went to put it back on, I followed tutorials I saw on YouTube, but whenever I try to do it, the key remains flat against the keyboard and won't spring back up. All the hooks, scissor key and metal parts are intact, and I don't know how to fix the caps lock key.
