How do you distinguish a mortice lock from a rim lock?

Question

Robert · Accepted Answer

A rim lock is what you would know as a Yale lock. Mortice is embedded into the side of the door, which is opened by a Chubb type key.

Barry · Answer

A mortice lock is recessed into the door and are square or rectangular and usually have a square key, but some mortice cases can be fitted with a cylinder lock.
A rim cylinder lock is the circle type top lock and is protruding through the door and the front is round with a round rim attached to the lock face and the handle/ knob turn is attached to the back of the door . 
Mortice-type locks are installed through the side of the door and are recessed into the door with just a small key opening at the front and back of the door.
Rim cylinders are installed in the door from inside to outside where the round lock face is situated and has only 1 key entrance at the front.
