1. The entrance door lock, also known as the anti-theft lock, is one of the most important security components of a home. As the main access point, it serves as the first line of defense against intruders. Most households have two doors: an outer iron gate and an inner wooden door. The iron gate typically uses a double-headed lock, meaning it can be locked from both sides. Common options include multi-point security locks or mortise steel door locks. When installing, make sure the distance between the two doors is at least 80mm (8cm). If they are too close, the handles might interfere, making it impossible to close both doors simultaneously, which could compromise security.
The inner wooden door usually has a handle lock that not only provides security but also adds to the overall aesthetic of the space. It’s designed for convenience while still offering a level of protection for the household.
2. Room door locks, especially for bedrooms, serve a similar purpose. These locks often require a key to open from the outside, or they may use a push-button or ball mechanism that allows access without a key. They are essential for privacy and security within the living space.
3. Bathroom door locks are unique in that they allow the door to be locked from the inside. However, they must also have an emergency release mechanism on the outside, ensuring that someone can open the door if needed. Some models come with visual indicators—like red and green lights or a small handle that shows whether someone is inside or not. This feature is crucial for safety and convenience.
4. Kitchen and corridor door locks are more functional than secure. They primarily serve as door handles to control airflow and maintain privacy. These locks don’t offer significant security features and are commonly used in storage rooms, children's rooms, or areas where full security isn't necessary.
