Yamaha Arius YDP-S54 key repair

Hi, after moving a Yamaha Arius YDP-S54 two of the black keys are higher than they should be and the white keys next to them scrape a little on the black keys when played. The van went over a big bump is what must have caused it.

Is this something I could try to fix myself? Unscrew all the covers and see if the keys have just jumped out of something and can be reset or if they’ve broken?

Thanks for any comments!
