A smart deadbolt replaces the existing bolt or ball lock with a keypad and fingerprint reader. It is the quickest upgrade for flats, serviced apartments, offices and short-term rentals.
Who uses smart deadbolts?
- Landlords and property managers who need temporary codes for guests
- Apartment owners who want to retire metal keys
- Offices and small shops
Check the door first
The D3 is designed for door thickness of 35-50 mm. Measure your door and, if it is thicker, contact us before you order. Photograph the existing lock to check the hole layout: the detail page shows the D3 replacing ball locks and old deadbolts directly.
Unlock methods that matter in rentals
- Keypad with virtual password: enter extra digits before and after the real code to hide it from onlookers (6 correct digits are enough).
- Temporary codes through the app: time-limited passwords for guests, cleaners and tradespeople.
- Fingerprint and IC card: for residents.
- Key: a backup that survives dead batteries.
Auto-lock and anti-lock
Auto-lock closes the bolt after a delay set in the app, and an interior button blocks outside entry. Both help property managers who cannot rely on guests to lock the door.
Battery life
The D3 detail page lists up to 6000 unlocks per set of batteries. Rental properties with frequent turnover should check batteries between guests.
Colours and capacity
D3 is available in black or silver and stores up to 100 passwords.
