Modeling a Basic Door Lock

Houses use doors to keep some of their areas safe. As a matter of fact, houses use various types of doors. To apply these safety measures, doors use locks. Doors in turn use various types of locks. For example, external and internal doors may use different types of locks. Normally, locks used on external doors use keys. In this exercise, we will model a simple door lock.
