P-120 Keys Stuck After Drop

[LoveTruth108]

Hello there. I am looking to fix my friends keyboard. I found a YouTube video which shows the break-down of the piano which is great. However I'm curious if anyone has any insight into the keyboard before I take it apart. Should I try to disassemble and fix before ordering the keys? Will it take more than just the keys (springs/hammers) to fix? The Reddit post here has the two images of my situation.

I would take it apart first BUT do take them out in order and store them in order.

Being graded each key is a different weight so the last thing you want is to get them mixed up.

A Tech will not necessarily know what is wrong until it is opened.
