The Front Door You Never Have to Think About Again

Four ways this lock makes sure you get in, including on the day something goes wrong.

Never locked out, even if the battery dies

Your fingerprint, a mechanical backup key, and a USB power port that brings the lock straight back to life. You also get a low battery warning long before it ever gets that far.

check_circle
Opens in a second, every time

Place your finger on the sensor and the door opens. No app to load, no code to remember, no second attempt. Same result at 7am with coffee in your hand and at 2am in the rain.

Backup key included in the box

Two mechanical keys ship with every lock, and the cylinder they turn is Class C, the highest of the three grades. The way in without electronics is real hardware, not a token gesture.

Kids and guests get in without keys

Register a fingerprint for everyone who lives there. No spare under the mat, no copy floating around with a sitter, and nobody standing outside waiting for you to get home.

You Will Not Need a Locksmith

  • Step 1: Swap It Onto Your Door

    Take the old knob off and put this one on. One screwdriver, no wiring, no drilling, and every part you need is already in the box.

  • Step 2: Add Your Fingerprints

    Register a print for everyone in the house. It takes seconds per person, and you can add or remove people whenever you need to.

  • Step 3: Touch and Walk In

    Put your finger on the sensor and the door opens in about a second. The backup key stays in your pocket for the day you decide you want it.

    Frequently Asked Questions

    You still get in. There is a USB emergency power port on the lock, so a power bank or a phone cable wakes it up on the spot. You also carry a mechanical backup key, and the lock warns you the battery is low well before it is actually flat. Three separate ways in, and none of them depends on the other two.

    Use the key. Two mechanical backup keys come in the box and they turn a Class C cylinder, which is the highest of the three lock core grades. Getting into your own home never depends on the electronics working.

    No. The fingerprint sensor sits on the lock itself and reads your finger whether your internet is up, your router is down, or your phone is dead. The app is a convenience, not the way in.

    If your door has a round knob lock on it today, this replaces it. It is a straight swap onto standard residential doors, and the strike plate, closure box and every screw you need are already in the box.

    One screwdriver, no drilling and no wiring. Every buyer who described the installation in a review called it easy or straightforward, and several said it took minutes.

    Usually yes, and here is the honest answer rather than the marketing one. Fingerprint sensors read the ridge pattern on your fingertip. Very small fingers, very dry skin, and fingertips worn smooth by manual work can occasionally need a second touch or a fresh registration. That is true of every fingerprint lock on the market, not just this one. If that describes someone in your house, register two different fingers for them, and remember they still have the backup key. Nobody in your household ends up dependent on the sensor alone.

    Yes. Register a fingerprint for everyone who lives there, and add or remove people whenever your household changes. No spare key under the mat, and no copy floating around with a sitter or a contractor you no longer use.

    It removes the risks that actually happen to people. Keys get lost, copied, lent out and never returned, and the spare under the mat is the weakest point on most houses. Here, access is something you grant and remove, and you always know exactly who can open your door. The cylinder underneath is Class C, so the mechanical route is not the soft spot either.
