I knocked a key off my keyboard, please help!

So one night, i was being an idiot with an empty phone box and ended up throwing it at my laptop, knocking the ctrl key off the keyboard. it came apart in three pieces and i can’t figure out how to get them back on. It makes it harder to find repair guides because every key hinge type is different. i have attatched a photo of the key so theres a better chance of getting the thing fixed!

Please help me out ASAP as this laptop is only 2 months old and i can’t afford to break it.

Thank you so much for your help!
