What type of lock is commonly installed for added security in residential properties?

1. Deadbolt lock

2. Mortise lock

3. Padlock

4. Cam lock

The correct answer is: Deadbolt lock

A deadbolt lock is commonly installed for added security in residential properties due to its robust design and resistance to forced entry. Deadbolts feature a solid metal bolt that extends deep into the door frame, making it much harder for intruders to break open a door compared to standard spring latch locks. They are available in single and double-cylinder versions, which can provide further security options based on the specific needs of the home. While other types of locks, such as mortise locks, padlocks, and cam locks, each serve their purpose in different applications, deadbolts are particularly favored in residential settings for their strong security features. Mortise locks are typically more complex and often used in commercial applications, while padlocks are portable and not as effective for securing entry points. Cam locks are usually used to secure cabinets and other furniture rather than doors. Thus, the deadbolt stands out as the most suitable option for residential security.
