When choosing a connected lock, one question comes up again and again: Wi-Fi or Bluetooth? Both let you control your door from your phone, but they work very differently. This guide from Covlor® compares a Wi-Fi smart lock against a Bluetooth model so you pick the right connectivity.
How Bluetooth Smart Locks Work
A Bluetooth lock pairs directly with your phone over a short range (around 10 metres). It is simple, battery-friendly, and needs no internet — but you must be near the door to use app features. Read more about Bluetooth.
How Wi-Fi Smart Locks Work
A Wi-Fi lock connects to your home network, so you can lock, unlock, and get alerts from anywhere in the world. It uses a little more power but delivers true remote control. Learn about Wi-Fi.
Wi-Fi vs Bluetooth: Key Differences
| Feature | Bluetooth Lock | Wi-Fi Lock |
|---|---|---|
| Range | ~10 m (near door) | Anywhere with internet |
| Remote unlock | No | Yes |
| Away alerts | No | Yes |
| Battery use | Lower | Slightly higher |
| Needs internet | No | Yes (for remote) |
| Best for | Simple local access | Full remote control |
Which Should You Choose?
Choose Bluetooth if you only need app control at the door and want maximum battery life. Choose Wi-Fi if you want to let people in remotely, check your door while away, or receive instant open alerts — the right pick for most homes and offices. Either way, local unlock by fingerprint, PIN, and key still works. Compare it with a biometric comparison too.
Frequently Asked Questions
Is a Wi-Fi or Bluetooth smart lock better?
Wi-Fi is better for remote control and away-from-home alerts; Bluetooth is simpler and uses less battery for local access. Most homeowners prefer Wi-Fi.
Does a Wi-Fi smart lock work without internet?
Remote features need internet, but you can still unlock locally with fingerprint, PIN, card, or key at any time.
Do Bluetooth locks let me unlock from far away?
No. Bluetooth only works within about 10 metres. For remote unlocking, choose a Wi-Fi lock.
Which uses more battery?
Wi-Fi locks use slightly more power, but long battery life and low-battery alerts keep them practical.
