The locks on our doors are really quite clever and quaint. They add to the charm of living in an old building in Centro Historico Mazatlan. The door latch is directly controlled by a spring-loaded rod that you pull out to open the door. If you want to leave the door unlocked, there is a lever that you move to hold the rod in the extended position. There is no knob on the outside of the door. You either leave the door unlocked or you use the key to move the rod.
