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.

Dual-mode Security

After entering your PIN, the lock requires a second authentication (Card or Fingerprint) before unlocking. Maximum security for sensitive areas.

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.
