When securing a home, the first line of defense is the door lock. If you need a new lock installation, there are many varieties you can choose. Many homeowners decide to install deadbolts to secure doors that work with latches. The guide below provides an overview of how both options work to help you understand why this is a popular setup.

How Do Door Latches Work? 

Many door handles and knobs have built-in latch locks. These can be engaged or disengaged from indoors by turning a small knob on the handle. People outside use keys. 

When a door is closed, this option’s spring-loaded bolt engages with the strike plate, which is the metal part that surrounds the mechanism at the side of the door frame. The bolt disengages when someone turns the handle from inside the home or uses a key. 

Since it’s so common, this setup comes in a wide variety of styles and finishes to match your home. Many options come with matching deadbolt locks for added security.

How Do Deadbolts Work? 

Deadbolt locks are commonly used as secondary security systems. They aren’t connected to door handles, but sit somewhere above the main locks. 

Deadbolts are typically thicker and heavier than latch locks, with most varieties made of brass, steel, or bronze. Their bolts extend deep into the door frames, providing extra security. Unlike latches, which often lock automatically when people close their doors, these need to be manually engaged.

Standard deadbolts work via knobs indoors and keys outside. Surface-mount varieties are only used inside homes, with their locking mechanisms inaccessible from outside.
