If they are tidally locked, there won't be any tidal friction, would there?

I don't think so, if I remember correctly only the orbital distance and eccentricity affects tidal friction. Synchronous orbit aka tidal locking doesn't change anything mentioned above.

Tidal friction is caused by the planet's rotation. The tidal force deform the planet, and the rotation drags the deformed shape to be misaligned with the moon.
