Residential locksmith services in Willowbrook IllinoisKeeping your home and family safe is a top priority for any homeowner. One crucial aspect of home security is the type of locks installed on your doors.

With so many different types of residential locks available, it can be overwhelming to choose the right one for your home. To help you make an informed decision, this residential locksmith in Willowbrook, Illinois is going to review the various types of residential locks and their features below.

An Introduction to Residential Locks

Residential locks are designed to provide security to your home by preventing unauthorized access. They come in various shapes, sizes, and designs, each with its own unique features.

Some of the most common types of residential locks include deadbolts, knob locks, lever handle locks, mortise locks, and smart locks. Each of these locks has its pros and cons, depending on your specific needs.


Deadbolts are one of the most popular types of residential locks. They are installed on the door frame and provide a high level of security due to their sturdy construction.

Deadbolts come in three main types: single-cylinder, double-cylinder, and lockable thumb turn. Single-cylinder deadbolts have a keyhole on one side and a thumb turn on the other. Double-cylinder deadbolts have a keyhole on both sides, while lockable thumb turn deadbolts have a thumb turn that can be locked with a key.

Deadbolts are highly effective against forced entry, as they cannot be easily picked or bumped. They are also relatively affordable and easy for residential locksmiths in Willowbrook, Illinois to install. However, they are not as ideal for doors with glass panels, as an intruder can break the glass and reach in to unlock the deadbolt from the inside.

Knob Locks

Knob locks are another popular type of residential lock. They are installed on the door handle and are easy to use, making them a great option for interior doors.

However, knob locks are not very secure, and they can be easily picked or bumped. They are also susceptible to brute force attacks, as they are often made of weaker materials than other types of locks.

There are two main types of knob locks: keyed entry knob locks and passage knob locks. Keyed entry knob locks require a key to lock and unlock them, while passage knob locks do not have a key and are used for interior doors.

Lever Handle Locks

Lever handle locks are somewhat like knob locks, but they have a lever-shaped handle instead of a knob.

They are easier to operate for people with disabilities or arthritis. Lever handle locks are also typically more secure than knob locks, as they are harder to pick or bump.

Lever handle locks come in two main types: keyed entry lever handle locks and passage lever handle locks. Keyed entry lever handle locks require a key to lock and unlock them, while passage lever handle locks do not have a key and are used for interior doors.

Mortise Locks

Mortise locks are one of the oldest types of locks that are available. They are installed inside the door and require a pocket or mortise to be cut into the door to accommodate them.

When properly installed by a residential locksmith in Willowbrook, Illinois, mortise locks are highly secure — they do a good job of withstanding brute force attacks and picking attempts. They come in two main types: cylinder mortise locks and mortise exit devices. Cylinder mortise locks require a key to lock and unlock them, while mortise exit devices are used on emergency exit doors and do not have a key.

Smart Locks

Smart locks are the latest type of residential locks that are becoming increasingly popular due to their convenience and high-tech features.

Smart locks can be operated remotely using a smartphone app, and some models can be integrated with other smart home devices such as security cameras and smart thermostats.

There are several types of smart locks available, including keypad locks, Bluetooth locks, and Wi-Fi locks. Keypad locks require a code to lock and unlock them, while Bluetooth locks use a smartphone’s Bluetooth signal to unlock the door. Wi-Fi locks connect to your home’s Wi-Fi network and can be operated remotely using a smartphone app.
