Secure, flexible access - with five unlock modes
Fingerprint sensor recognises enrolled prints, keypad accepts user codes and privacy passwords, NFC and mechanical key provide alternative entry, while app-based unlocking enables remote access. Incorrect password attempts trigger an audible alarm, which can be adjusted.
Multiple access options reduce reliance on physical keys and make daily entry quicker for family members. Alarm and logging help detect unauthorised attempts and increase household security.
Private entry control - with privacy and temporary passwords
Privacy password uses random digits before and after the correct code, masking the actual password during entry. Temporary and frequent unlocking modes allow time-limited codes to be issued remotely.
Guests, cleaners or contractors can be given one-off or limited-time access without sharing permanent credentials. Privacy codes keep PIN entry obscured from onlookers.
Reliable power and emergency access - with battery monitoring and USB interface
Runs on four AAA batteries, with a low battery warning that prompts replacement and an expected operational span of around six to nine months. A USB interface permits emergency charging to regain entry if batteries fail.
Battery monitoring reduces the risk of unexpected lockouts, while USB emergency power means access can be restored quickly without drilling or replacing the whole unit. Regular checks keep the lock dependable.
