How to replace keyboard

Hey Allan , I saw the videos and the weird thing with this model is the keyboard back plate is a metal plate and attached to the plastic body with plastic rivets of a sort. So one has to chip those rivets off to get to the keyboard

Youtube video doesnt do a great job a showing how the new keyboard and the backplate can be secured properly to the chassis without introducing any keyboard flex.

If you could share how professionals perform keyboard replacement would be very helpful
