You didn't show how to remove the Fan. You removed the Fan and Heat Sink. There's 4 more screws. Finish the job.

I removed the Keyboard from the Top Case and replaced the Keyboard. It wasn’t too bad with my Heat Gun and all-in-one painters tool…yes you heard right, my handy dandy painters tool that has served me well for years. Anyway, the only problem area taking the Keyboard out and snapping it back in (if you want to call it that) was by the DVD Player. Good Luck!

The Keyboard still has to be removed from the Top Case! Your not done yet!
