Smart door lock hacking is an ever-increasing threat to the security of businesses and homeowners alike. As technology evolves, so are the methods used by hackers to gain access to secure areas. If you haven’t been staying up to speed with the newest security requirements, then you may have to face hostile attacks at any time. Therefore, having knowledge of how to hack a smart lock can save you upfront.

In this article, we will attempt to cover every potential method that attackers can use to break your security, so that you can be educated and take the required precautions ahead of time. Let’s have a look at them now.

Techniques Of Smart Door Locks Hacking

Attackers employ a variety of methods to hack a door lock, ranging from physically breaking the lock to deploying the most powerful malicious software. Rather than physically visiting the site, some advanced methods allow attackers to break the protection of your home remotely.

Let’s look at all the many technologies that hackers can employ to make your smart door lock vulnerable.

1. Physical Breaking And Entry

One of the most basic methods of gaining unauthorized entry into a locked room is through brute force. This involves attacking the physical components of the lock such as drilling or picking.

While this method works well with traditional mechanical locks, it is less effective with current digital locks. Because they feature some added security measures like tamper-proof coatings or alarm systems. If someone tries to get unauthorized access, the authorities are immediately notified.

2. Social Engineering Attacks

Social engineering assaults are schemes in which offenders employ deception or trickery to persuade someone. They utilize lawful access to reveal sensitive system information or to unlock a door without authority.

These attacks usually entail convincing someone with valid access to provide credentials via email or other means. This can then be utilized for malevolence purposes.

Some popular forms of social engineering include –

  • Phishing emails,
  • Pretexting (making false claims),
  • Baiting (intimidation & coercion), and
  • Tailgating (following people into restricted areas)

3. Exploiting Software Vulnerabilities

Hackers can also exploit software vulnerabilities in order to gain access to smart door locks.

In many cases, these vulnerabilities exist due to coding errors that weren’t caught during testing phases. This may allow malicious actors an opportunity to breach the system through privilege escalation or buffer overflows if they know where to look.

It is important for companies developing these products to have proper security assessments done on them before releasing them publicly. As these measures can reduce the chances for exploitations from occurring later on down the road.

4. Exploiting Network Connections And Protocols

In today’s interconnected world it is becoming increasingly common for smart door locks to utilize wireless networks for controlling them from afar. Though they greatly simplifies installation processes but also provides an increased attack surface for malicious actors.

Insecure connections or poorly set up protocols lacking authentication methods, such as WPA2-PSK encryption standards prevalent in Wi-Fi networks, are a great source for hackers to gain unauthorized access.

Companies must therefore guarantee that all communication methods used between devices are appropriately secured using robust encryption algorithms.

It would thus assist clients in ensuring that they are not vulnerable to wireless attacks via packet sniffing tools such as Wireshark, which are readily available online for free.

5. Password Cracking Techniques

Password-cracking techniques are another important threat vector usually connected with hacking attempts against smart door locks. In this method, hackers usually use running proprietary software built specifically to find a valid username/password combination.

Such software allows attackers full control over devices or forces them open via brute force methods if no user credentials are available.

These kinds of software usually depend on massive databases comprising hundreds or thousands of regularly used passwords. They gather them from leaked sources on the internet. As a result, it is frequently a highly successful method of breaching weakly protected systems.

6. Internet Of Things (IoT) Attack Vectors

Nowadays, we rely heavily on Internet-of-Things (IoT) devices such as Alexa, Google Home, and Nest. These IoT gadgets provide an excellent chance for attackers to compromise smart door lock systems. Attackers can simply gain access to those platforms by employing zero day exploits. As a result, our security is subject to compromise.

When traditionally a hacker would need physical proximity to break open a locked door, modern IoT technologies make it possible to bypass these extra layers of security by leveraging existing infrastructure already installed inside the home without detection. It leaves only a digital trace behind making it difficult to trace source compromise after the fact.

7. Using Malware Or Spyware To Gain Access

Malicious programs, such as malware and spyware, can be installed on computers connected by the same local area network. If the targeted device is connected through the same public wifi hotspots, attackers can gain access to them via a backdoor. Thus it allows attackers to exploit or break any safe smart door lock systems.

Keyloggers and Remote Access Trojans (RAT) are two typical types of harmful malware.

Both of these are capable of capturing keystrokes entered on the keyboard without the user’s knowledge and secretly transmitting captured data back to the attacker’s server. This later enables them to rebuild sophisticated PIN combinations required to unlock doors in just a few trials if necessary.

8. Compromising Cloud-Based Technology Used By Manufacturers

One way hackers can attack smart door locks is by exploiting vulnerabilities in the cloud-based systems used by manufacturers to power their products. If hackers can gain access to these systems, they will be able to gain control of the functionality and settings of the door lock.

They could then modify the internal settings to allow them access without needing any authentication tokens.

Hackers may also be able to intercept or manipulate data stored in these systems, opening up further possibilities for infiltration.

9. Reverse Engineering To Uncover Security Flaws

Another method employed by malicious actors is known as reverse engineering. This involves closely examining the source code of a program or device in order to uncover potential security flaws or vulnerabilities.

By understanding how a particular system works internally, hackers can exploit weaknesses that would otherwise remain undetected or difficult for regular users to identify.

This allows them to bypass authentication measures such as PIN codes and passcodes, giving them access to secure areas without needing any authorization tokens whatsoever.

10. Algorithmic Insecurities In Smart Keypads And Swipes Cards

Finally, some smart door locks rely on algorithms encrypted into keypads and swipe cards for authorization purposes. Unfortunately, these algorithms are not always robust enough against attacks from sophisticated hackers who understand how they work inside out.

If hackers manage to crack the algorithm used by a particular manufacturer’s product, they will be able to bypass all authentication measures without having any authorization tokens at all – unlocking the door with ease!


Malicious actors can hack into smart door locks through a variety of methods. They can utilize traditional means such as physically breaking door locks to more advanced methods such as cloud-based technology, reverse engineering code, and exploiting algorithmic flaws.

With this in mind, it’s crucial for business owners and households alike to take every precaution necessary when choosing their smart lock solutions. Users must also keep their system up to date with all available software updates.

As a result, knowing how to hack a smart lock, regular audits of hardware and software security measures are required to ensure constant, optimal protection for their premises. Where necessary, third-party consulting services should also be considered.
