3-in-1 Keyless Entry for Interior Doors

The Meterk MD1BUS fingerprint door knob provides three unlocking methods: fingerprint, keypad, or physical key. It suits bedrooms, offices, garages, and other interior doors that open outward or have narrow stiles. An auto-lock function secures the door after five seconds of inactivity, while a one-touch lock button offers immediate locking.

Sustained Operation and Power Backup

Four AA alkaline batteries (not included) deliver up to one year of typical use before replacement is needed. When batteries deplete, a Type-C port on the bottom accepts power-bank input to revive the lock temporarily. The fingerprint sensor uses intelligent learning, so recognition speed and accuracy improve with repeated scans over time.

Pre-Installation Checks for Your Door

Verify that your door thickness and backset match the tubular cylinder specification and that the handing suits an out-opening, narrow-stile configuration. Ensure you have a Phillips screwdriver for the four-step installation and a supply of quality AA alkaline batteries, as they are not supplied in the box.

Questions about this item

How much battery drain should I expect from the Type-C emergency port if I use it daily?

The Type-C port is for emergency power only when the four AA alkaline batteries are depleted; it does not charge the batteries and draws no power when not in use.

Does the lock come with the four AA alkaline batteries it needs to operate?

Batteries are not included; you must supply four AA alkaline cells from a reputable brand to power the lock.

Will this knob replace my existing tubular-cylinder interior door hardware without new holes?

It fits most US interior doors that already use a tubular cylinder; a Philips screwdriver is the only tool required for the four-step installation.
