Question Faulty Xbox controller button

[Jeffzeh]

Hi,
I have an xbox replica controller from ThrustMaster. Since the past few months, the "B" button needs to be pressed really hard to get an input from it. How can i fix this issue?
Thanks

Well I have no idea whats causing it so I have no idea how to fix it. If you're comfortable with it take the controller apart and make sure there are no dirt or debris around the button.
