Your dog walker needs to get in. Your parents are stopping by. A friend needs to grab something while you're away.
Do you really want to keep making copies of your house key?
With a smart door lock, you don't have to.
Meet the new HIDALIFE 669FK Fingerprint Door Knob and 669FL Fingerprint Door Lock with Handle—designed to make everyday access easier, whether you're coming home, welcoming family, or giving someone temporary access.
Both models are available in Satin Nickel and Matte Black.
Your Finger Is the Key
Why carry a key when you already have the perfect one with you?
Both the 669FK and 669FL feature fast fingerprint recognition that unlocks your door in as little as 0.3 seconds.
They can store up to 50 fingerprints, making them convenient for family members and trusted guests.
Just place your finger squarely on the sensor, and you're in.
More Ways to Unlock
Not every situation calls for a fingerprint.
Both locks support:
- Fingerprint access for quick everyday entry
- Keypad codes for family and regular users
- One-time temporary codes for guests, deliveries, rentals, and more
So if someone needs to get inside while you're out, you can share a temporary code instead of handing over a spare key.
Easy to Use, Even at Night
Coming home late?
The backlit keypad makes entering your code easier in the dark. And with Silent Mode, you can unlock the door quietly without waking everyone up.
It's a small feature that can make a big difference when the house is already asleep.
