6 Ways to Unlock – Keyless Convenience for Every Situation

Say goodbye to lost keys and forgotten passwords. The LAOLAU B04 offers six versatile unlock methods to suit any scenario:

Fingerprint – Advanced biometric sensor unlocks your door in under 0.5 seconds for lightning‑fast access

TTLock App (Bluetooth) – Unlock with your smartphone when within Bluetooth range

Passcode – Create permanent, timed, one‑time, or recurring codes

IC Card – Contactless RFID cards for quick tap‑and‑go access

Mechanical Key – Physical backup keys included for emergency use

Remote Access – Unlock from anywhere with the optional Gateway

Remotely Manage Guest Access – Perfect for Rentals & Airbnb

Need to let in guests, cleaners, or family members when you're not home? The TTLock app lets you generate and send time‑limited eKeys or temporary passcodes remotely. Set passcodes for specific dates and times – they automatically expire after the designated period. No physical key exchange, no worry about copies being made.

Full Access History – Know Exactly Who Came and Went

Wondering who entered your home while you were away? The TTLock app stores and displays a complete unlock history, showing exactly who entered and when – whether via fingerprint, card, or passcode. With the optional gateway, you'll also receive real‑time notifications for every entry.

Anti‑Peep Password – Keep Your Code Truly Private

Worried about someone watching you enter your passcode? The camouflage unlocking feature lets you add random digits around your true password. Onlookers and hidden cameras will see a string of numbers – but only you know which ones are real.

Fits Any Door – Reversible & Adjustable Handle

The handle is fully reversible and adjustable, easily configurable for both left‑handed and right‑handed doors. This universal design ensures a seamless fit for any room layout or door opening preference – no complicated adjustments needed.

Never Get Locked Out by a Dead Battery

Running low on battery? The lock includes an integrated Type‑C emergency power interface. Simply connect an external power bank to instantly power up the lock and unlock your door – you'll never be locked out due to a dead battery.
