About this item
- 50 Fingerprints + 20 User Codes Stores up to 50 fingerprints and 20 user codes. Easily add or delete users anytime—perfect for family, tenants, or staff.
- Vacation Mode + Rekey + Silent Mode Vacation mode limits entry to programming code and key only. Rekey lets you change the cylinder to match a new key (Kw1 keyway)—professional locksmith and specialized tools required, not a DIY task. Silent mode turns off all beeps.
- Security + DIY Install Keypad locks out for 1 minute after 5 failed attempts. Low-battery alert reminds you to replace the 9V battery. Fits doors 1.37″–2.17″ thick, 2-3/8″ or 2-3/4″ backset, with a 2-1/8″ (54mm) door hole，installs in 15 minutes with just a screwdriver.
- Keypad + Fingerprint + Key 3 ways in—user code (4–8 digits), fingerprint (fast one-touch), and physical key (backup). Anti-peep function lets you type random digits around your real code (up to 40 total) to keep your password safe from onlookers.
- Auto-Lock + Passage Mode Auto-locks in 5 seconds (adjustable 2–99s). Press the top two buttons on the interior assembly to switch to Passage Mode—free entry with just a knob turn from outside. Perfect for gatherings or hands-free access.
