Smart Lock DIY DL03 Pro Ezviz
The EZVIZ DL03 Pro is a smart rim lock that connects directly to your home 2.4 GHz Wi-Fi, with no hub needed. You can open the door with a fingerprint, a passcode, a proximity card or remotely from the EZVIZ app, and it runs on four AA batteries.



Four ways to unlock: The lock stores up to 50 fingerprints, 50 proximity cards and 50 passcodes (6 to 10 digits), and also supports remote unlocking from the app. Every family member can use the method that suits them, and fingerprints are processed and stored locally on the lock.
Direct Wi-Fi, no hub: The DL03 Pro pairs straight with your home 2.4 GHz Wi-Fi, so there is no extra gateway to buy before you can control it from the EZVIZ app, check the lock status and manage users.
Visitor access: You can create temporary passcodes for visitors (valid up to 1 year) and grant or revoke access from the app, for example for relatives, a babysitter or a delivery.
Auto-lock and door-left-open alert: The lock checks the latch status itself and locks automatically when you close the door. If the door is left open, it alerts you.
Alerts and anti-tamper protection: You get real-time notifications of door activity, low battery and repeated wrong attempts; after 5 wrong entries within 5 minutes the keypad locks for 3 minutes. If someone tries to forcibly remove the lock, it sounds a siren.
Works with EZVIZ cameras: The DL03 Pro can trigger a linked EZVIZ camera to start recording when the door is opened, so you see who comes in. EZVIZ lists these compatible cameras: H6c, C6N, CP1, TY1, TY2, H3 and C8W.
Good to know
Wi-Fi is 2.4 GHz only. The lock is powered by 4 AA alkaline batteries (included) and supports an emergency power supply. Camera integration only works with the EZVIZ cameras listed above.
