I just brought my MacBook Pro with the same issue with the b key. Apple is aware of the issue and have create a quality program to replace with a redesign top case that addresses this issue. We’ll see if this is true in 5 days. This is my 4th time getting repaired. If it’s not fixed this time around I will be escalating for a complete replacement.
