Special Features

Random Number Feature​

Add random digits before/after your PIN to prevent shoulder-surfing. Total entry can include up to 20 digits.

Multi-touch Security​

After entering your PIN, the lock displays 3 random digits. Press those digits to unlock. This prevents fingerprint-pattern leakage on the keypad.

Auto/Manual Lock Mode​

Toggle between automatic locking (locks 2 seconds after door closes) and manual locking (you touch the keypad to lock).

Sound Volume Control​

Adjust operation sound across 7 levels via the keypad.

Sound Mute​

Mute the operation sound for one use (e.g. late at night). Sound returns automatically afterward.

RFID Card Auto/Manual Detection​

In auto mode, the card reader is always awake and unlocks door when tapped. In manual mode, wake screen first then tap.

Dual Mode Security Setting​

Requires two authentications (PIN + RFID Card or Fingerprint) to unlock the door for maximum security.
