Dead Lock

A deadlock is a type of lock that can only be operated with a key, both from the inside and outside. It does not have a spring mechanism, which makes it more secure against forced entry.

A deadlock uses a key to move a bolt into place, securing the door. Since it requires a key to lock and unlock from both sides, it provides enhanced security by preventing unauthorised access.

Deadlocks can be installed on most types of doors, including wooden, metal, and composite doors. However, the suitability may depend on the specific design and structure of the door.

While it's possible to install a deadlock yourself, it is recommended to hire a professional locksmith to ensure proper installation and optimal security.

While deadlocks are commonly used on external doors for security, they can also be used on internal doors where additional security is needed, such as in office settings or storage rooms.
