Squeaking noise of keyboard

I can’t find similar topic from naive searching so maybe I’m an outlier in the statistics? Anyway, the problem is when I put some very light force on some of the keys they will squeak like rubbing a balloon. It only happens to several keys. The worst key happens to be “J” and I happen to be a vim user, so it’s quite annoying. When typing quickly (hammering the keys) there is no such noise but when pressing “J” slowly it will appear. Anyone has similar experience? Is replacing the keyboard the only solution?
