Smart locks are changing how commercial properties manage access. They allow business owners to grant or revoke access remotely, monitor entry activity, and eliminate the need for physical and spare keys. They’re especially popular in office buildings, retail spaces, warehouses, and multi-tenant properties where managing access for multiple people is critical.
But as these systems grow in popularity, so do the questions surrounding their safety, chief among them: Are smart locks safe, and can they be hacked? In this article, we’ll explore how smart locks work with commercial entry doors, their vulnerabilities, and how to protect your business by making wise choices in lock technology, installation, and ongoing security.
What Are Commercial Smart Locks and How Do They Work?
Smart locks use wireless technology and internet connectivity to control access without a physical key. Commercial models have more advanced technology than residential models used in a home security system, including access logs, customizable user permissions, and integration with broader access control systems.
Most commercial smart locks are managed through cloud-based platforms or secure mobile apps. Authorized users can lock and unlock doors remotely, set time-based access schedules, and receive real-time notifications when doors are opened. For businesses managing multiple employees, service providers, or tenants, this level of control offers significant advantages over traditional lock entry.
Commercial-grade smart locks are also designed to work with other security systems. They can sync with security cameras, alarms, and building automation systems for centralized control. Many models also support multiple authentication methods, such as access codes, mobile credentials, key cards, or even biometric verification for high-security environments.
This combination of connectivity, access control, and flexibility makes smart locks appealing to business owners. However, with these benefits come potential risks, particularly when the locks are not installed or managed correctly.
Can Smart Locks Be Hacked?
Smart locks offer convenience and remote access control, but they come with cybersecurity risks like any internet-connected device. Most successful breaches occur under specific, avoidable circumstances. By understanding common mistakes and implementing simple security best practices, businesses can significantly reduce the chance of unauthorized access. The table below outlines the most frequent security errors associated with smart locks, why they’re risky, and how to prevent them effectively.
| Mistake | Why It’s a Security Risk | How to Prevent or Improve It |
|---|---|---|
| Using weak or default passwords | Attackers often exploit easily guessable passwords or default manufacturer codes. | Use strong, unique passwords, PINs, and two-factor authentication when possible. Avoid default passwords and simple patterns (like “1234”), and never reuse credentials across devices. High-security models allow for a one-time PIN code to reduce long-term exposure. |
| Not regularly updating firmware | Devices that don’t receive timely updates, especially those protecting primary entry points like the front door, are far easier to exploit because unpatched vulnerabilities can be used to hack the smart lock. | Schedule and apply regular firmware updates. Setting calendar reminders, staying informed about manufacturer updates, and taking proactive measures, such as working with a technician to promptly apply patches. |
| Poor network security practices | Connecting smart locks to an unsecured or public Wi-Fi network greatly increases the chances of unauthorized access. | Only connect smart locks to secure, password-protected networks. Avoid public Wi-Fi and consider using a dedicated network for security devices. Enable strong encryption protocols on all routers. |
| Misconfiguration during installation | Improper installation, such as enabling unnecessary features, failing to set permissions, or ignoring recommended security settings, can expose the system. | Hire a professional for proper setup. They’ll ensure the lock is configured securely, permissions are properly assigned, and non-essential features are disabled to reduce attack surfaces. |
| Choosing consumer-grade locks | Locks designed for residential use often lack the enhanced security protocols necessary for commercial applications. | Choose commercial-grade, well-built smart locks designed for business use. These models offer advanced encryption standards, better support, and features appropriate for a commercial environment. |
| Granting access too freely | Giving access to too many users or failing to remove access for former employees creates unnecessary risk of internal breaches. | Only allow essential personnel to gain entry. Audit user access regularly, remove ex-employees promptly, and assign access based on specific roles and responsibilities. |
| Failing to monitor lock activity | Without monitoring, suspicious activity may go unnoticed until a breach occurs. | Enable alerts and comprehensive monitoring. Many smart locks offer notifications for failed attempts, unusual activity, and other data. Reviewing these logs regularly helps detect and respond to threats early. |
Comparing Smart Lock Types by Security and Vulnerability
Not all smart locks offer the same level of protection. The access method, type of connectivity, and overall configuration of lock settings influence how secure a keyless lock is and how likely it is to be compromised. Choosing the right type depends on your security needs and your business environment.
| Smart Lock Type | Description | Relative Security | Common Vulnerabilities | Best For |
|---|---|---|---|---|
| Keypad / PIN code locks | Users enter a numeric code to gain access | Medium to high | Susceptible to weak PINs, shoulder surfing, or code sharing | Small offices, service-based businesses |
| Locks with bluetooth communication | Pairs with a user’s smartphone within a close range | Medium | Vulnerable if the paired device is stolen or Bluetooth is spoofed | Co-working spaces, retail backrooms |
| Wi-Fi-connected locks | Managed via cloud-based apps; allows remote access and real-time monitoring | Medium to high | Can be hacked via network weaknesses or outdated firmware | Multi-location businesses, remote properties |
| Biometric locks | Uses fingerprint or facial recognition to authenticate access | High | Lower risk, but vulnerable if sensor quality is poor | Medical offices, law firms, and secure offices |
| RFID / key card locks | Access is granted via scannable cards or fobs | Medium | Cards can be lost, cloned, or intercepted | Hotels, schools, shared access buildings |
| Hybrid smart locks | Combine two or more methods (e.g., biometric + PIN + app access) | Very high | Risk is minimized when features are configured correctly | Warehouses, tech offices, high-security areas |
Are Smart Locks or Traditional Locks More Secure?
Smart and traditional locks have individual strengths and weaknesses. Understanding the differences helps business owners choose the right solution for their property and risk level.
| Feature / Risk / Consideration | Traditional Locks | Smart Locks | Which Performs Better? |
|---|---|---|---|
| Access control | Requires physical keys; changes need rekeying or lock replacement | Remotely grant or revoke access instantly | ✅ Smart locks |
| User management | Manual key distribution; no easy way to track who has keys | Role‑based digital credentials; logs show exactly who accessed when | ✅ Smart locks |
