Razer Raiju Ultimate square button ''broken''

Hi, My square button recently started to get stuck deeep in push and having a hard time clicking back up and down, still works but it's mostly unusable if you want to click it more then twice in a row... bought it 2 years ago so im guessing warranty if of the table. I tried open it but could get past the first screws and poping the part off, too afraid to damage it. I live in belgium maybe any chance theyre is a repair service available or somth ? idk if i could fix that on my own.
