Digital Door Locks: What Actually Matters Before You Buy

Feature lists across digital lock brands look nearly identical. Here is what separates a lock you forget about from one that annoys you weekly.

Door compatibility comes first

HDB fire-rated main doors have specific thickness and mortise requirements. Bring a photo of your door edge and existing lock body when you visit — it takes thirty seconds and rules out half the catalogue.

Battery behaviour

A good lock warns you for weeks before batteries die and offers an emergency power contact. Avoid models that rely solely on a mechanical key hidden somewhere in your bag.

Face recognition versus fingerprint

Face recognition is faster with full hands, but placement matters — it must sit at a comfortable height for everyone in the household. Fingerprint remains the more reliable everyday option in wet or humid conditions.

After-sales service

Locks are the one fixture where local service response time matters most. We only carry brands with in-country technical support and stocked spare parts.
