B Key on Rhodes is sticking - can it be shaved down?

[abelovesrhodes]

I've moved this B Key around to a few spots and it displays the same behavior, so I'm pretty sure its the key. Other B Keys work in that keys location. Is the key malformed? Can I just sand it down on either side?

I've read other posts, but this case is clean, we literally just built it and I've looked - there is nothing inside there. The hammer isn't stuck between tines. It's just the key.

Are you sure its the sides? 
Do you have calipers at your disposal to verify?
What about the felts?  Does it need to be eased?

(Just questions, with a boatload if disclaimers and precursors.)

Definitely not sure of anything, but I figured that since it sticks regardless of the octave that it is the fit with other keys. I do have calipers - what should I measure? I'm sure since the key is wood it will flex with temperature and humidity. The bridles are fine, and the felts are fine too, as they play fine with other Bs in their place.

If I misunderstood - my apologies - let me know.

I suspect the key bushings (red felt in the holes on the underside of the key) need easing. i'd do that first.
