We are all interested in protection of our families and houses. The deadbolt locks are designed to secure our doors and prevent an unauthorized entry.
There are two main types of locks on the market – the conventional deadbolts and the smart locks. So what is the most secure door lock?

What's On This Page?

Each type has its advantages, so let’s review them.

Conventional Deadbolts

Conventional deadbolts are simpler; they provide no special functions, except for keeping your house safe. They are well-constructed and durable, usually single-cylinder locks.

There are double cylinder deadbolts, specifically designed for the doors, which are placed near the window. They prevent the forced opening through breaking the window.

These items are usually not very expensive and they are easy to install. I’ve picked several options among the conventional deadbolts.
