Basic of Smart Door Locks

As we have explored the key differences between smart door locks and traditional locks, let's now delve into the basics of smart door locks to understand their working principle better.

How does a smart door lock work?

Smart locks are high-tech door locks that work without a physical key. You can control them using a smartphone app; some have a keypad for easy entry. They connect to WiFi to receive commands from your phone and can be part of a complete smart home system, working with other smart devices like speakers and security systems through a smart home hub.

Smart locks let you send virtual keys to guests via text or email, allowing them entry without you being present.

Types of smart door locks

  • Bluetooth smart locks: These locks connect to your smartphone using Bluetooth technology. When your phone is near the lock, it automatically detects it and allows you to unlock the door without physically interacting with the lock.

  • WiFi smart locks: These locks connect directly to your home's WiFi network, enabling remote access and control through a smartphone app from anywhere with an internet connection.

  • Deadbolt locks:  Deadbolt locks are a popular choice for enhancing door security. They use keys or biometric authentication for unlocking and offer additional protection against forced entry. Often, people combine deadbolt locks with other smart locks for increased security measures.

  • Smart lever locks: Smart lever locks are innovative smart lock systems that replace traditional door handles and locks. They offer a popular choice for upgrading the appearance of doors while providing an added layer of security.

Basic of Traditional Door Locks

Traditional locks, such as single or double deadbolts, knobs, and mortise locks, require manual engagement. They typically use keys, with common types like rim locks, pin-tumbler locks, or mortise locks. When a key is inserted, the lock's components, including spring-loaded pins and cylinders, work together to unlock the door.

Traditional locks have been regarded as secure ways to protect items such as homes, offices, cars, or safes.

Smart Door Lock vs. Traditional: Pros and Cons

When comparing smart door locks and traditional locks, it's essential to weigh their respective pros and cons to make an informed decision about which option best suits your security needs.

Smart Door Lock pros and cons


  • Remote access and control: With smart door locks, you can remotely lock or unlock your door using a smartphone app from anywhere.
  • Convenience: No need to search for your key fob in your bag; the automated version of the smart lock opens your home with a simple trigger or responds to your voice commands.
  • Enhanced security: Smart door locks offer advanced encryption and authentication protocols to resist picking and bumping, providing heightened security levels. Additionally, some models come with extras like anti-theft capabilities, intrusion alarms, two-way talk, and built-in cameras, further enhancing the safety of your home.
  • Activity monitoring: Many smart locks offer activity logs, allowing you to track when your door was locked or unlocked.
  • Integration with smart home: Smart door locks can be seamlessly integrated into a complete smart home ecosystem, working in tandem with other smart devices like cameras, speakers, and security systems for enhanced automation and security.


  • Reliance on technology: Smart door locks depend on electronic components and connectivity, making them vulnerable to power outages or system malfunctions, potentially leading to lockouts.
  • Installation complexity: Certain smart lock models may require more complicated installation procedures or professional assistance, leading to added costs.
  • Hacking risks: With internet connectivity, smart locks may be susceptible to hacking attempts or cyber breaches, potentially compromising home security.

Traditional Door Lock pros and cons


  • Cost-effective: Traditional locks are generally more budget-friendly than smart locks, making them an economical choice for many homeowners.
  • Simple operation: Using a physical key to lock and unlock doors is straightforward and familiar to most people.


  • Risk of lost keys: The reliance on physical keys increases the risk of lost or misplaced keys, potentially leading to security issues or the need for costly rekeying.
  • No remote access: Without electronic components, traditional locks lack the convenience of remote access and control, limiting flexibility in managing home security.
  • Susceptibility to bumping and picking: Traditional locks may be susceptible to picking or bumping by skilled intruders, potentially compromising home security.

Smart Door Lock vs. Traditional: How Secure Are They

Determining the security level of a traditional and smart lock involves considering several factors.

How secure is the traditional door lock?

Locks primarily meant for exterior doors are also suitable for interior doors like bathrooms and closets. However, using a Grade 1 security lock on a bathroom door is excessive. On the other hand, relying solely on a knob lock without a deadbolt for your front door makes your home vulnerable to attacks and burglars.

The lock's strength depends on how frequently it's used. If you have a Grade 2 or 3 deadbolt lock on an infrequently used interior door, it's not a significant security risk. But, using a Level 3 security lock on a front door with daily foot traffic creates a vulnerability that could be exploited.

How secure is the smart door lock?

Smart locks and traditional locks have similar security levels in most cases because smart locks don't make significant architectural improvements to the basic lock design. However, people often perceive smart locks as better due to the added features they offer.

Most smart locks can be used with an existing deadbolt, making them more secure than using a Euro Cylinder lock on the front door. However, the drawback is that it's challenging to make additions to smart locks due to their specific design.

Smart locks introduce a new concern: cyber attacks. They are vulnerable to external cyber attacks, and many manufacturers struggle to address the consequences of hacking smart locks. These attacks can compromise personal data and other important aspects of a person's life.

To enhance smart lock security, homeowners can take measures such as investing in high-security firewalls for their home network and regularly changing network passwords and access codes.

What to Consider When Buying a Smart Lock?

  • Compatibility: Check if the smart lock is compatible with your door type and existing hardware. Some smart locks are designed to retrofit onto standard doors, while others may require specific door preparations or professional installation.
  • Connectivity options: Determine how the smart lock connects to other devices or your smartphone. Common connectivity options include Bluetooth, WiFi, Zigbee, or Z-Wave. Choose a lock that aligns with your home's connectivity infrastructure and offers the desired remote access level.
  • Security features: Pay attention to the security features offered by the smart lock, such as advanced encryption, two-factor authentication, tamper alerts, and anti-picking/bumping capabilities.
  • Price and warranty: Compare the prices of different smart locks and weigh their features against the cost. And check for warranty coverage to ensure long-term support.

1. Are smart locks safer than key locks?

The safety of a lock depends on various factors, including its build quality, installation, and usage. Smart locks, when properly implemented and used in conjunction with best security practices, can offer a high level of safety. However, both smart and key locks have their place in home security, and the choice will depend on your specific needs.

3. Are smart locks hackable?

Smart locks can be vulnerable to hacking due to potential weaknesses in passwords, Bluetooth or WiFi communication, software, social engineering, or physical tampering. To minimize risks, users should use strong passwords, keep software updated, and only purchase smart locks from reputable manufacturers with a focus on security. While no technology is completely hack-proof, taking precautions can significantly enhance the security of smart locks.

4. Are smart locks easier to break into?

The vulnerabilities may include digital weaknesses, remote access risks, software bugs, lost or stolen devices, and potential battery issues. To enhance security, users should use strong passwords, keep software updated, and combine smart locks with traditional physical security measures.
