macbook keyboard troubles.
Got 2016 MacBook Pro and my F9/ next song key is working but not clicking like the other keys. Makes quieter click noise and needs to be pushed down little bit more further/pressed harder them the other keys to register like spongier if that makes sense just only notice really. Thought about taking the key of and cleaning it but don't want to damage it. Would anyone else have an idea on what could be wrong before I remove it. Also know how to remove the function keys is it like the main keys as I've seen some tutorials as to removing those keys.
MacBook Pro, macOS Sierra (10.12.6), Non Touch bar
