Control
Every way in, in your hand.
Fingerprint. Passcode. An RFID card. The TTLock app on your phone. A mechanical key when you simply want one. Grant a digital key to family for good, or to a cleaner for a Tuesday, and withdraw it just as easily.
Calm
One touch and you're in.
No patting pockets on the doorstep, no digging for keys with your arms full. A fingerprint or a code opens it in an instant, and there's always a mechanical key in reserve. Add the optional Wi-Fi bridge and you can unlock from your phone, or ask Alexa and Google Home, from anywhere.
Craft
Compact and discreet on your door.
The KF is a small, tidy smart lock that fits standard doors, not a bulky panel bolted onto a good one. The weatherproof keypad sits neatly on the outside, ready the moment you reach for it.
