The locks that you have on the doors of your home provide essential protection for your family and your belongings. Locking your door at night or when you are away from home can help keep unwanted intruders from getting in, ensuring that you stay safe.

Today’s locks come in many different styles, ranging from relatively basic to extremely high tech. When choosing locks for your home, it is important to familiarize yourself with available options. If you are ready to start learning more, keep reading for details on five popular types of locks for houses from locksmith expert.

Doorknob Locks

These are the locks that you are probably the most familiar with. Doorknobs are commonly installed on both interior and exterior doors. In the center of locking doorknobs, there is a small keyhole that can be used to lock or unlock the door. In most cases, the door can only be unlocked with the key from one side. On the other side, there is a knob you can turn or button that you can push to lock the door.

Most experts only recommend using doorknob locks on interior doors. That is because they can easily be compromised. If the doorknob itself is damaged or knocked off of the door, the cylinder inside can be accessed, making it simple for anyone to break-in. That generally isn’t a concern when locks like these are used on interior doors. However, it is a lot more problematic on exterior doors. The last thing that you want is for someone to be able to easily get inside your home.

Deadbolt Locks

The design of these locks is relatively straightforward. A knob known as a thumb turn is mounted on the inside of the door. When the knob is turned, a heavy-duty bolt extends from the door into the door frame, preventing the door from being opened. This style, which is known as a single deadbolt, is the most common. They have a thumb turn on the inside and a keyhole on the outside.

Double deadbolts, on the other hand, have keyholes on both sides. That means that you have to use a key to lock or unlock them since there is no thumb turn.

Electronic Keypad Locks

Some locks are designed to be opened with an electronic keypad rather than a key. To open the door, you need to punch the correct entry code into the system. One of the biggest benefits of locks like these is that they allow you to access your property even if you don’t have your keys with you. That means that you don’t have to worry about getting locked out if you accidentally leave your keys inside.

They are also a great solution for families. Instead of having to give everyone their own key to get into or out of the home, you can simply have all of your family members memorize the entry code.

Most of these locks make it easy to update the code. That means that you can frequently change it to keep your home even more secure. You can also set up a code for a housesitter or pet sitter if you are going to be out of town. That means that you don’t have to pass out spare keys to your home.

Smart Locks

These locks are similar to electronic keypad locks. The primary difference is that they can be controlled remotely using a smartphone, tablet, computer, or another device. That means that you can lock and unlock your home with your phone, even when you are away. In many cases, you can also control them with your voice.

Like electronic keypad locks, you can set up separate access codes for other people. The primary difference is that these smart digital locks give you even more control. For instance, you can set the hours during which each code is valid, helping to keep pet sitters or other people from entering your home when they shouldn’t be there.


These locks typically aren’t used on entry or exit doors. Instead, they are most commonly used on outbuildings like sheds or garages. Oftentimes, they are used in conjunction with other locks as a way of adding extra security to a door.

Hopefully, this overview of five of the most popular types of locks for houses will make it easier for you to decide which style is the best option for your home.
