You’ve probably heard of digital locks and smart locks when shopping for a modern security upgrade in Singapore. But here’s the catch — they’re not the same thing. While both ditch the traditional key, they serve slightly different purposes. This guide breaks it all down simply so you know exactly what you’re buying and why it matters for your HDB, BTO, condo, or landed home.
1. What is a Digital Lock?
A digital lock is an electronic locking device that allows you to open your door without using a traditional key. Think of it as a keyless entry system that focuses on convenience and security.
Common Unlocking Methods
- PIN codes
- RFID cards
- Biometric fingerprint
- Mechanical override key (in some models)
Ideal User Profile
Digital locks are perfect for homeowners who want a simple, secure solution without connecting to Wi-Fi or downloading apps. It’s user-friendly, especially for seniors or anyone not tech-inclined.
2. What is a Smart Lock?
A smart lock is a digital lock with advanced features, mainly connectivity. These locks can link to your smartphone, smart hub, or even voice assistant.
Advanced Connectivity Features
- Wi-Fi, Bluetooth, or Zigbee connectivity
- Remote locking and unlocking
- App notifications and visitor logs
Remote Control Access and Automation
You can unlock your door from anywhere with an app — ideal for letting in family, friends, or even couriers while you’re at work or overseas.
3. Key Differences
| Feature | Digital Locks | Smart Locks |
| Connectivity | Operate independently without the need for internet or app connectivity | Connect to Wi-Fi or Bluetooth for remote access and smart features |
| Access Methods | Access via PIN codes, RFID cards, or mechanical keys | Access using PIN codes, RFID cards, mechanical keys, and smartphone apps |
| Remote Access | Not supported — must be operated directly on the device | Fully supports remote unlocking, granting/revoking access, and viewing entry logs |
| Security | Highly secure from cyber threats due to no online connection | Offers activity logs and alerts, but may be exposed to cyber risks if not properly secured |
| Cost | Budget-friendly and cost-effective | Typically more expensive due to advanced technology and smart capabilities |
| Smart Integration | Not compatible with smart home systems | Easily integrates with smart home platforms like Alexa, Google Assistant, and Apple HomeKit |

4. Installation & Compatibility
Both digital locks and smart locks can be installed on a wide range of residential door types, including HDB, BTO, condominium, and landed property doors. The installation process is generally straightforward and does not require major modifications to the existing door structure.
In terms of compatibility, most models are suitable for wooden laminate doors, fire-rated doors, and metal gates. For metal gates, specific gate-compatible lock models may be required.
These locks are powered by batteries, with an average battery life ranging from six months to one year, depending on usage. Most models come with built-in low battery alerts to ensure timely replacements and uninterrupted operation.
5. Which One Should You Choose?
Key Decision Points
- Want app control, guest codes, and remote access? Go smart
- Prefer simplicity and reliability? Stick with digital
Usage Preference vs Future-Proofing
If you plan to build a smart home ecosystem, a smart lock is a better long-term investment. Otherwise, digital locks provide all the basic security you need.
Final Thoughts
Choosing between a digital lock and a smart lock boils down to your lifestyle. If you love the idea of controlling your door from anywhere, a smart lock is a no-brainer. But if you just want solid security without tech fuss, a digital lock is perfect. Either way, you’re upgrading your home’s security and convenience — and that’s a smart move in any case.
