Smart locks, especially older models, are pretty secure, but their battery life isn’t great. If you don’t have your manual key, you’ll have a hard time getting into your home or room. Well, DESLOC came out with one that’ll last you for a year or more.
DESLOC has launched the K120 Smart Lock, built for families and landlords who want a stable, long-lasting lock with fingerprint access that works every time.
The K120 is a practical alternative to feature-heavy smart locks that often fall short. It uses DESLOC’s GPT Fingerprint Recognition, a 15,000mAh battery, and built-in Wi-Fi to deliver reliable security for everyday use.
The K120is already available on Amazon and DESLOC.com. It’s designed to solve common smart lock problems like failed fingerprint scans, battery issues, and tricky setup.
Built for the People, Smart Locks Often Fail
Many smart locks promise new features, but users still deal with unreliable fingerprint readers, short battery life, and spotty connections. The K120 is built for households tired of these problems.
The K120 uses DESLOC’s GPT Fingerprint Recognition, which reads dry, wet, or worn fingerprints in 0.15 seconds. It learns and improves accuracy the more you use it.
3D recognition with live detection blocks fake fingerprints, and all biometric data stays on the device, not in the cloud, for better privacy.
This means unlocking works reliably for seniors, kids, workers, and anyone who has had trouble with fingerprint readers before.
Power That Lasts — and Doesn’t Surprise You
Battery life is a big concern for smart lock owners. The K120 uses a 15,000 mAh battery that lasts up to 13 months on a single charge.
When the battery drops below 10%, you’ll get an alert in the app. If it goes under 5%, the lock switches to Ultra Save Standby Mode. There’s also a USB-C emergency power port so you can always get in.
DESLOC focused on real-life battery use, aiming to deliver a lock that won’t leave you locked out with a dead battery.
Designed for Both Families and Landlords
The K120 stores up to 50 fingerprints and lets you unlock with a fingerprint, passcode, app, or key. Built-in Wi-Fi lets you lock or unlock remotely, receive alerts, and check door status without a separate hub.
Families get auto-lock with magnetic door sensing, anti-peek passcodes, temporary codes, and smart home support for Alexa and Google Assistant, all without extra hassle.
Landlords and property managers can use Landlord Mode to control multiple properties, set schedules, manage groups, and handle tenant access, all from the DESLOC SmartControl App.
The system is built to reduce maintenance costs, reduce tenant complaints, and make property management easier over time.
Everyday Simplicity Meets Certified Durability
You can install the K120 in about 10 minutes. It automatically detects left or right doors, so you don’t need to recalibrate. Modes like Passage, Do Not Disturb, and Vacation let you adjust the lock for different needs.
The K120 is rated IP65 for weather resistance and has BHMA Grade 3 certification, making it suitable for daily use in various environments.
DESLOC built the K120 for consistency, with stable connections, tough hardware, and reliable performance over time.
