Chances are that you will encounter mortise locks on business doors, exit devices and or keypad lock.
But not only. Sometimes, they can be a great setup for residential doors as well, even though this is less common. Here are some key features of mortise locks:

1. Design: Mortise locks can appear in a variety of shapes and colors, which is one of the reasons
they are so commonly used.

2. Security: Mortise locks are usually a part of metal latch and deadbolt, which makes them a more
secure option and therefore providing enhanced resistance against forced entry. In addition, the
deadbolt is usually operated by a key, thumb turn, or a combination of both.

3. Versatility: Mortise locks can be used for various types of doors, including wooden, metal, and
glass doors (mostly for entrance doors such as gas stations). They come in different sizes and
shapes to accommodate different door thicknesses and security requirements. In addition, they
can be installed as interchangeable cores, which usually comes with a unique set of keys for key
control.

4. Durability: While there are different grades for every mortise lock, they usually considered of a
better quality than most standard locks as they have to function more frequently on entrance
doors, exit doors etc.

5. Key options: Mortise locks can be found in both single-cylinder and double-cylinder variations
from all major lock brands including Schlage, Kwikset, Falcon and more. In addition, you can find
“dummy” mortise locks as you can only unlock the cylinder from one side. (Usually installed on
exit doors)
