Are keyless door locks secure? Everything you need to know!

The feeling of coming home after a long day and realizing your door key is nowhere to be found, can be very frustrating. So, if you’re considering getting a keyless door lock, you’re not alone.

However, there are several things you might need to consider before investing in a keyless door lock. One of the questions you might want to ask is - “Are keyless door locks secure?”

To help you understand the security of keyless door locks, we’ve created this guide explaining the most important things you must know about keyless door locks, ranging from their features to their potential vulnerabilities, and lots more.

Part 1: What is a Keyless Door Lock?

A keyless door lock is a new security device that uses electronic or biometric authentication to open the door. Unlike traditional door locks, a keyless door lock can be controlled remotely and integrated with smart home systems for added security and automation.

How Do Keyless Door Locks Work?

Keyless locks use a combination of microprocessors, authentication sensors, and electromechanical components to manage access.

There are basically two main kinds: manual keyless locks and smart locks.

Manual keyless door locks are non-electronic door locks that use mechanical keypad, push buttons, or combination dials to allow entry. These locks do not require batteries, electricity, or wireless connectivity, making them reliable even during power outages or electronic failures.

Smart locks, on the other hand, use wireless connectivity like Wi-Fi, Z-wave or Bluetooth to enable you to lock doors or unlock doors remotely. Many are also embedded with auto-locking features for more convenience and efficiency in security provision.

Part 2: Types of Keyless Door Locks

There are various types of keyless door locks available.

• Keypad Locks

Keypad locks are keyless door locks that allow you to unlock the door using a coded keypad. This type of keyless door lock usually features a numeric keypad where you enter a code to unlock the door, and it's highly customizable.

Keypad locks are ideal for any place, including a smart home, office, or rental. And the best part about using it is that you can set codes to expire after a specific period, preventing unauthorized access.

• Biometric Lock

Keyless locks in the biometric category introduce a higher level of security, relying on your biometric data to unlock your door. This type of keyless lock includes fingerprint locks, palm recognition locks, facial recognition locks, etc.

What sets biometric lock systems apart is that they cannot be recreated like keys or pins (for keypad locks). They rely on the biometric data stored in their system, and if it’s a match, the lock opens.

• Bluetooth-enabled Locks

A bluetooth lock automatically opens when your phone is in range, with no need to pull out your keys or type in a code, and it’s a good option for integrating into your smart home. However, there’s a catch. Their reliability is vulnerable!

If your phone is lost or compromised, a bluetooth lock can become a security concern.

• Wi-Fi Enabled Lock

Wi-Fi-enabled locks have the highest levels of remote access and control when it comes to keyless locks. This type of lock allows you to lock and unlock your doors from anywhere via Internet connection.

Also, some WiFi locks come with a security camera to surveillance your front door. So, they are very useful for frequent travelers or homeowners who want to closely monitor their property.

The only downside about keyless Wi-Fi locks is that they have a high battery consumption and are more susceptible to cyber threats. To ensure security, choosing a model with two-factor authentication and regular firmware updates is crucial.

• RFID Locks

RFID locks offer a mode of access using key fobs, cards, or even using mobile devices. When an RFID device is within close range, its RFID reader communicates with the chip embedded in the lock and opens the door.

RFID locks are widely applied to hotels, offices, and commercial properties owing to the ease of use they present besides giving centralized access management. For example, hotels can reprogram the RFID key cards easily for new guests without changing the locks. However, if lost or stolen key fobs are not deactivated on time, they present a severe security risk.

Part 3: Security Features of Keyless Door Locks

Now that you understand what keyless door locks are, let’s dive into the security features they offer.

1. Advanced Authentication Methods

Keyless door locks use encryption authentication methods to enhance security. Many models use biometric scans such as fingerprints, palm vein recognition, or facial recognition, while some rely on PIN codes, which can be easily customized for different users.

Additionally, some keyless smart locks support two-factor authentication for the app and website login, making it much more difficult for intruders to enter.

2. Integration with Home Security Systems

Many keyless locks are designed to seamlessly integrate with home security systems. When connected to a smart home ecosystem, these locks can work with security cameras, motion sensors, and alarm systems.

3. Automatic Locking Features

Keyless door locks often support an automatic locking function that allows your door to automatically lock in case you accidentally left it open. Once the door is not closed, the lock engages after a pre-set time (such as a few seconds), eliminating the need for manual locking.

Additionally, certain smart locks offer geofencing, which locks or unlocks the door based on your phone’s location.

4. Real-Time Monitoring and Alerts

Another incredible security feature in keyless locks is real-time monitoring and instant alerts. This feature helps to stay informed about your property’s security.

Keyless door locks with real-time monitoring can send you notifications for lock activity, including successful entries, failed attempts, or forced entry. Some even generate detailed access logs, showing who entered and when.

5. Resistance to Physical Manipulation

Keyless door locks use the latest authentication techniques to provide enhanced security. Many of them use biometric scanning to ensure only an authorized user will have access. Others rely on PIN codes, which can easily be changed for different users.

6. Biometric Data Storage and Protection

Most keyless locks that feature fingerprint or facial recognition store this information on the device rather than on cloud servers; this reduces the risk of hacking and unauthorized information disclosure.

They use advanced encryption technologies such as AES-128 or even AES-256 encryption to guard against data compromise due to some sort of cyber threat.

Part 4: Potential Vulnerabilities of Keyless Door Locks

While keyless door locks offer advanced security and convenience, they are not without risks. In this section, we explained some of the vulnerabilities of keyless door locks,

• Risk of hacking

Keyless door locks that use an internet connection are prone to hacking attempts.

Some of the common ways hackers compromise such keyless door locks is via weak password, outdated firmware, or insecure communication channels.

• Power source failures

Keyless door locks still rely on power from batteries to function smoothly. These batteries can die unexpectedly, leaving you locked out unless you have a backup.

• Software Issues

Wireless internet can be vulnerable to signal interference or jamming attacks. Hackers can use techniques like signal jamming devices to temporarily prevent access.

• Signal Interference

Keyless locks operate using embedded software, which, like any digital system, is prone to glitches, bugs, or security vulnerabilities.

Part 5: Comparing Keyless and Traditional Locks

Both keyless and traditional locks serve the same purpose—securing entry points—but they differ in functionality, convenience, and security features. While traditional locks rely on physical keys, keyless locks use digital authentication methods such as PIN codes, biometrics, or mobile apps. Below is a comparison table of both lock types to help you determine which best suits your needs.

Part 6: Helpful Tips to Enhance the Security of Keyless Door Locks

There are three main tips you must know when using a keyless door lock to enhance the security of your home (or any space).

● Regularly Update Access Codes and Firmware

Keyless door locks use a multilayered security system to prevent intruders. However, not updating their firmware or using the same PIN code for too long increases the risk of unauthorized access.

It’s important that you update your access code (for keypad lock) and firmware frequently to reduce the risk of intrusion.

● Ensure Robust Physical Installation

A keyless lock is only as secure as its physical installation. This is why you must invest in high-quality materials and ensure the lock is securely fastened to a reinforced door and frame.
