What is the difference between Wi-Fi and Bluetooth smart locks?
Smart locks offer keyless convenience and enhanced security, but choosing between Wi-Fi and Bluetooth models can be confusing. Both technologies serve the same basic purpose—remote access—but they differ in range, power usage, and smart home compatibility.
In this guide, we’ll break down:
How Wi-Fi and Bluetooth smart locks work
Key differences in performance and security
Which type is best for different living situations
Top lock recommendations for each technology
By the end, you’ll know exactly which smart lock type fits your lifestyle.
1. How Wi-Fi and Bluetooth Smart Locks Work
Bluetooth Smart Locks
- Short-range wireless connection (up to 30-50 feet)
- Phone acts as the “key” – Unlocks automatically when you approach (geofencing)
- No internet required – Works offline, ideal for remote cabins or areas with poor Wi-Fi
Wi-Fi Smart Locks
- Internet-connected – Uses your home Wi-Fi network
- Remote access from anywhere – Lock/unlock via app, even when you’re miles away
- Works with voice assistants – Alexa, Google Home, and Siri integration
Key Takeaway:
- Bluetooth = proximity-based control (good for personal use)
- Wi-Fi = full remote access (better for rentals or frequent travelers)
2. Key Differences: Range, Power, and Security
| Feature | Bluetooth Smart Locks | Wi-Fi Smart Locks |
|---|---|---|
| Range | 30-50 ft (phone must be nearby) | Unlimited (works globally) |
| Battery Life | 6-12 months (low energy usage) | 3-6 months (higher drain) |
| Internet Required? | No | Yes |
| Hacking Risk | Low (direct device pairing) | Moderate (network-dependent) |
| Best For | Single-family homes | Rentals, Airbnb hosts |
Battery Life Comparison
- Bluetooth: Lasts longer
- Wi-Fi: Drains faster due to constant network communication
Security Notes
- Bluetooth is harder to hack remotely but vulnerable to close-range relay attacks.
- Wi-Fi depends on your network security—use WPA3 encryption and strong passwords.
3. Which One Should You Choose?
Get a Bluetooth Smart Lock If You…
Live in a house (not an apartment) – No need for remote access
Want longer battery life – Fewer battery changes
Prefer simplicity – No Wi-Fi setup required
Get a Wi-Fi Smart Lock If You…
Rent out your home (Airbnb, VRBO) – Issue temporary codes remotely
Travel often – Check if doors are locked from your phone
Use smart home systems – Works with Alexa/Google routines
4. Future-Proofing: Hybrid Locks & New Tech
Many newer smart locks now offer both Bluetooth + Wi-Fi, giving you the best of both worlds. Other advancements include:
Thread/Matter support – More reliable than Wi-Fi for smart homes
Z-Wave integration – Popular for professional security systems
Biometric backups – Fingerprint or facial recognition
Final Tip: If you can’t decide, get a dual-connection lock for maximum flexibility.
