Defining Locks

The description of a lock depends on how it is mounted to your door and frame. Apart from that, there are other important factors to look at when it comes to understanding these types of locks. 


Also known as deadbolts, a deadlock is manually operated through the use of a locking mechanism that involves the turn of a key or a thumb turn. This type of lock is considered to be one of the most secure; the reason being the effort and amount of force needed to pray the bolt back. 

Mortice Lock

If you are into aesthetics, then this lock will appeal to you. Mortice locks are fitted inside the door edge and usually, its cylinders are inserted into a hollow or “mortice” in a door’s edge. This serves as the lining for a recess in the frame for the bolt to fit into. When your door is ajar, you can only see the face plate and keyhole; and this goes back to the look of the entire door and frame. 

Mortice locks also fall into the category of combinations of most secure door locks. The former statement can be proven true with how home and business insurance policies prefer to see a mortice lock for you to meet compliance with the terms and conditions of your insurance cover with them. 

8 Demarcations of a Deadlock and Mortice lock

Home security is of paramount importance and convenience alone does not cut it. There are many factors to consider when choosing a lock; such as ease of use or difficulty of burglar entry. With these two locks, we have highlighted how they are the two most secure locks you could go for, in combination with others. However, let us delve into the differences between the two: 

  • Mortise locks are typically used in commercial areas that need extra security. 
  • Mortise locks can only be operated by a key.
  • Unlike deadlocks, you will need at least 2 copies of the key to avoid losing one. 
  • Mortise locks are also ideal for homes that need high security.
  • Deadlocks can be used independently or in conjunction with a normal door knob.
  • With Mortise locks, you can keep the key in the locks on the inside to make locking the door easier. 
  • With Deadlocks, once the key is turned, the deadlock is thrown and can’t be re-opened without a key. 
  • A deadlock is usually placed higher than the handle on a door, and on the inside, there is a door knob.
