A Kaadas smart lock is one of the most popular digital lock choices in Singapore, thanks to a wide range that covers HDB fire-rated doors, condo timber doors and even mortise-style installations, often bundled and installed through local dealers like My Digital Lock. Kaadas offers 3D face recognition, fingerprint, PIN, card and app unlocking across push-pull and lever designs, so there is usually a model to match your door and your budget. This guide walks through the Kaadas smart lock line-up available in Singapore, what to check before installing, and which model fits your home.
We wrote this for HDB and condo owners deciding between Kaadas models and weighing them against Yale, igloohome and Aqara. Kaadas is often sold as part of an installed bundle in Singapore, so the real cost and experience depend heavily on the dealer, the promotion and how well the lock is fitted to your specific door and gate. We therefore focus not just on the hardware but on the practical questions that matter locally, such as fire-door compatibility, backup power and how easy it is to hand out temporary access. We judged each pick on unlock methods, build and finish, door compatibility, battery life, app features and realistic SGD value including local installation. Digital lock prices vary a lot by dealer and promotion, so treat all figures as indicative ranges and confirm the latest bundle and installation quote before buying.
