Can Smart Locks Be Hacked? 4 Common Attacks & How to Prevent Them

Smart locks offer convenience, but are they really secure? In this guide, we break down four of the most common smart lock attacks — from brute force to Wi-Fi hacking — and show how modern locks like the Lockin Veno Plus are built to prevent them. Learn how to protect your home with biometric access, encrypted connections, and real-time alerts.

Can Smart Locks Be Hacked? 4 Common Attacks & How to Prevent Them

Introduction

A smart lock can be targeted, and its security has to be assessed across the credential, account, communication path, and physical installation. The categories below describe questions to investigate rather than proof that a particular model has passed an attack test. Start with the exact product documentation and any applicable test report, then check the settings and recovery methods you will use at home. Convenience features such as remote entry or a camera do not replace that evidence.

Instead of sensationalizing the risks, let’s break down the four most common ways smart locks are attacked—and how you can prevent each one.

1. Brute Force Attacks

Credential Guessing

Repeated credential guessing is an access-control problem to address through the lock's supported settings. Use an appropriate PIN rather than a familiar personal pattern, limit who receives it, and check what the exact model documents about unsuccessful attempts. An app account and a keypad credential may have different controls, so manage them separately. Practise the recovery route before you need it, and do not assume that an alert or temporary restriction guarantees that an unauthorized person can never gain entry.

  • Use long, complex PIN codes (e.g., 6+ digits with no patterns)
  • Enable auto-lockout after multiple failed attempts
  • Turn on app alerts for failed unlock attempts

2. Man-in-the-Middle (MITM) Attacks

Command Authentication

Communication protection must be checked for the path used to send the command. Local biometric matching does not demonstrate how a phone app, remote service, or platform connection authenticates an instruction. Look for documentation that covers the relevant interface and the manufacturer's update process, rather than inferring protection from an encryption label alone. Keep the supported software current and remove access that is no longer needed; these are maintenance tasks, not a substitute for model-specific security testing.

3. Bluetooth or Wi-Fi Exploits

Wireless Interfaces

Bluetooth and Wi-Fi describe communication options, not a complete security verdict. A buyer needs to know which interface the installed model uses, what account or device can control it, and how the manufacturer supports updates. Product price or brand familiarity alone does not answer those questions. If a required capability is not documented, ask the manufacturer for its scope before relying on it, and keep an entry method that remains usable when the remote service or network is unavailable.

4. Physical Tampering

Physical Entry

Physical resistance depends on the lock, door, frame, and installation together. A camera or tamper notification may help someone notice activity, but it does not establish how the assembly resists forced entry. Compare the exact model's relevant test evidence and fit the hardware according to its installation guide. If the bolt binds or the door does not close correctly, correct the installation before relying on automated locking; successful recognition or an app command does not prove that the bolt has secured the opening.

How Lockin Helps You Stay Ahead

Apply the Checks to the Selected Model

Use the Veno Plus feature list to identify what needs checking, rather than treating it as an attack-test result. Confirm the supported credentials, the installed door's mechanical operation, the remote-control prerequisites, and who manages access. Keep the documented backup route available and revisit permissions when household members or guests change. This turns the security discussion into concrete purchase and setup questions without claiming that the presence of biometrics or video establishes universal superiority over a mechanical lock.

  • Palm vein recognition – hard to spoof, hygienic, and reliable even for kids or seniors
  • Local processing of a particular function does not establish that the whole lock sends no data to cloud services. Check the documented path for biometric information, account management, notifications, video, and remote commands separately
  • Real-time app alerts – know when your door is unlocked, and by whom
  • Built-in camera + 2-way talk – monitor and speak to visitors in real time
