Introduction: What Defines the Best Digital Lock in Singapore (2026 Edition)

For 2026, the best digital locks in Singapore combine advanced security technologies—such as biometrics, smart cylinders and tamper alarms—with simple, reliable daily use. Homeowners increasingly expect smart features like app control, activity logs and facial or palm-vein recognition that remain safe and intuitive for children and elderly users. Door compatibility is equally crucial, as Singapore homes use a mix of HDB wooden doors, metal gates, glass doors and sliding doors, making engineered fit and dual-sync door-and-gate unlocking valuable. Pricing spans from entry-level offline models for BTOs and rentals to premium AI-enabled locks with video intercom and smart-home integration, while strong after-sales support, local servicing and reliable emergency power options (USB-C or 9V) remain essential in Singapore’s humid, high-rise environment.

How to Choose the Right Digital Lock for Your Home in 2026

Choosing the right digital lock starts with your door or gate type and any regulatory requirements, then moves to user needs and smart features. A simple decision framework can help Singapore homeowners narrow down options quickly.

For fire-rated main doors in HDB or BTO flats, ensure the chosen lock and installation method do not compromise fire-rating requirements; fire-rated models like the Solity GEA1000K are specifically designed for such doors. If you have elderly family members or young children, prioritise locks with easy, contactless biometrics such as facial or palm-vein recognition on models like Interlock Mercury X6, Mercury G2 or Solity G1.

Homes with narrow metal gates or tight door–gate spacing should look at gate locks and bundles designed for HDB gates, such as Solity G1, Mercury G2, or coordinated bundles like X6 + G2 and GEA1000K + G1. For sliding or glass doors, avoid generic locks and instead select purpose-built models like Interlock Mercury GD1, Milre MDL-280F, or Mercury SD1 that match glass thickness and sliding clearances.

If you prefer offline security or have low-tech users, a lock like Interlock Mercury X2 provides digital convenience without Wi‑Fi, cloud accounts, or apps, which can be ideal for rental units or elderly occupants. Smart-home enthusiasts and those wanting remote unlock, logs, and integration with Apple Home, Google Home, or Matter should consider models such as Interlock X6, Mercury G2, Aqara U100, or the Solity bundles with Matter compatibility.
