Deadlocking Mortice Locks

Deadlocking mortice locks, also known as mortice dead locks, are a highly secure locking solution commonly used on external timber doors. Installed within the edge of the door, these locks operate using a key to extend a solid bolt deep into the door frame, helping to secure the door firmly in place. Because they do not include a latch mechanism, mortice dead locks are typically used alongside a separate latch or door handle, making them an effective choice for front and back doors where dependable security is essential.

A mortice dead lock provides strong protection by using a robust internal bolt that can only be operated with a key, preventing the door from being opened without proper access. Many models feature multiple internal levers, such as 5 lever designs, which increase resistance to tampering and picking. This makes deadlocking mortice locks a popular option for homeowners looking to strengthen their entrance door security while maintaining a discreet locking system built into the door.

Suitable for both new installations and replacement mortice dead locks, these locks are manufactured from durable materials to ensure long-lasting performance and smooth key operation. Available in a range of sizes and security grades, they can be fitted to a variety of timber doors in residential and commercial settings. Combining strength, reliability and proven locking technology, mortice dead locks remain one of the most trusted solutions for securing external doors.
