What's the Difference Between Regular Door Lock and Deadbolt?

You can’t compromise on security, which is why choosing the right type of lock for your home is essential. Regular entry door locks and deadbolts aren’t always the same and will have different pros and cons when it comes to protecting your home.

So what’s the difference between a regular door lock and deadbolt lock, and how do you know which products are best? Let’s take a closer look.

What is a Regular Door Lock?

There are many different locks used for exterior doors. The requirements for a door lock will vary by location and the type of property.

It’s important that you know what type of lock you have both for your own peace of mind and  because many home insurance providers will want to know the type of lock you’re using and the level of security at the property.

In most homes, a regular lock is typically operated by a key or knob and features a spring-loaded latch that retracts when the key is turned or the handle is used.

Though these locks offer a reasonable amount of security, they sometimes can be bypassed using simple lock-picking techniques or some force. This makes them ideal for secondary doors or internal doors, but not always entryways.

Let’s explore some of the most common lock types in homes.

Types of Regular Door Locks

● Knob Locks – Built into door knobs, these locks are easy to use but offer minimal security. These are better suited to internal doors as they can be easily broken with a reasonable amount of force.

● Lever Handle Locks – Lever-handle locks are extremely common both in the home and in businesses. More traditional lever handle locks will use a simple key, but more advanced (and secure) models may also require a code or have biometric features.

● Cam Locks – A cam lock should never be used on a door. These are most often found in cabinets and mailboxes because they’re very easy to open without a key.

What is a Deadbolt Door Lock?

Deadbolt locks are much more suitable for exterior doors and are one of the most common lock types used today.

A deadbolt door lock is a more secure locking mechanism that requires a key or thumb turn to retract a solid metal bolt that extends deep into the door frame. Unlike regular door locks, deadbolts do not rely on a spring mechanism, making them more resistant to forced entry and therefore acting as a more secure option.

Their strong locking mechanism and deeper engagement into the door frame make them difficult to pick, pry, or force open, offering peace of mind for homeowners and a significant challenge for intruders.

Types of Deadbolt Door Locks

What are the most common entry door locks and deadbolts for home security?

Single Cylinder Deadbolt

This is one of the most common types of deadbolt lock. It is operated with a key on the exterior and a thumb turn (or lock knob) on the interior. The thumb turn allows quick locking and unlocking from inside, offering convenience and simple security.

While single-cylinder deadbolts are secure against forced entry from the outside, they can be vulnerable if there is glass near the door. For example, if a window is close, an intruder could break the glass, reach through, and turn to unlock the door so it’s important to consider the surroundings when choosing this type of lock for your home.

Double Cylinder Deadbolt

Unlike the single cylinder, the double-cylinder deadbolt requires a key to operate both from the inside and outside. This adds an extra layer of security, especially in homes where a potential intruder could break a nearby window and unlock the door.

Vertical Deadbolt 

Vertical deadbolts are often used in high-security areas or where maximum protection is needed, such as in secure facilities or vault doors. They can also be seen in doors with large, heavy frames, like commercial buildings or industrial facilities.

The vertical mounting makes it more difficult for burglars to use leverage or prying tools to force open the door. It is particularly resistant to forced entry techniques such as "bumping" or "jimmying."

Can You Have A Deadbolt Lock With Door Knob Fixtures?

Yes, a deadbolt lock with door knob fixtures can work, and this combination is actually fairly common in residential doors.

The deadbolt is typically a separate lock mechanism from the door knob, mounted above or below the door knob on the door itself.

For added security, many people choose to have a deadbolt that is separate from the door knob’s latch mechanism, meaning that even if the door knob is tampered with or broken, the deadbolt still keeps the door securely closed.

Many modern homes will also incorporate smart locks, which can still be combined with traditional door knobs or handles for ease of use while maintaining high levels of security.

Main Differences Between Conventional Door Locks and Deadbolts

So what are the main differences between a traditional door lock and deadbolt, and which is better for your home?

Common Security Vulnerabilities

Both regular locks and deadbolts have their vulnerabilities, but depending on your priorities when it comes to security, there are superior products available.

Let’s have a closer look at where each of these options may be vulnerable.

Regular Door Lock Weaknesses:

● Lock Picking & Bumping – Many traditional locks can be picked or bumped open using simple tools. Things as simple as credit cards can be used to open older locks.

● Weak Latch Mechanism – Many regular door locks can be opened with some force. A kick can be enough to break more simple locks.

● Key Duplication – Key duplication is a common concern for those who lose keys or may have multiple people with access to a home or business. The best way to overcome this weakness in a system is to choose a lock with biometric features or unique access codes.

Deadbolt Weaknesses:

● Improper Installation – Though deadbolts are durable, a poorly installed lock may not engage deep enough into the door frame, reducing security. For door locks, security systems and smart home sensors, proper installation is absolutely essential.

● Key Control Issues – While deadbolts have better key security, unauthorized duplication is still a potential risk unless using high-security keys.

How might a regular door lock and deadbolt compare when put head-to-head?

The Peace of Mind of Having Good Home Security

Investing in a high-quality lock system is not just about security—it’s about peace of mind. A strong lock gives homeowners confidence that their property and loved ones are safe.

Benefits of a Smart Home Security System

Smart home security systems, including smart locks and sensors can provide real time alerts and notifications. This means you know who is entering and leaving your home 24/7, no matter your location.

You can grant limited-time access to guests, cleaners, or deliveries through temporary access codes or lock or unlock doors when needed through your phone.

These smart systems allow a perfect balance between security and convenience.

Biometric Security

Biometric security is becoming an important feature of modern home security systems, offering a higher level of protection compared to traditional keys and codes.

Though it may seem a luxury, it adds a completely new layer of security and provides a convenient and efficient alternative.

Benefits of Biometric Door Locks

How are advancements in biometric security making door locks for modern homes even more secure?

● Fingerprint Recognition – Eliminates the risk of lost or stolen keys and allows you to provide and remove access easily without keys.

● Multi-User Access – Allows multiple authorized individuals to access the lock with their fingerprints. Some locks will allow hundreds of prints to be stored for businesses and busy locations.

● Enhanced Security – Fingerprint locks are harder to bypass or open than regular door locks.

● Quick and Convenient – Instantly unlocks with a touch, making access seamless and quick.

Many smart locks, including Aqara models, feature biometric fingerprint scanners that ensure only authorized users can enter. Not only is this enormously convenient for quick access, but it
