2. What should be considered when purchasing a lock?

- Different applications require different locks. Several factors should be considered to avoid buying the wrong lock, including humidity, structure and thickness of the door, direction of door opening (inward or outward), and hinge location. The surrounding environment should also be considered, since the lock should fit the theme and style of the home. Ideally, the lock aesthetics will be consistent with the décor of the surrounding area.

- Different parts of the home require different locks. Determine if the lock will be used in a gate, front door, bedroom, bathroom, or hallway. It is also important to consider who will be using the door, since certain types of locks can be better for children, elderly family members, or people with disabilities.

- Be sure to evaluate the reputation of the dealer providing the locks. Some dealers may recommend poor quality or even fake locks to consumers. It’s best to purchase locks from a reputable manufacturer to avoid any potential issues with performance.

Wealthy families are able to purchase higher-end locks, while those with a lower economic status may need to choose one of lower grade. Regardless of economic status, it is important to consider the reputation of the manufacturer and the quality of their locks before making a decision.
