Digital Lock Singapore – Door & Gate Lock Specialists Since 2008

The Interlock’s Mercury X6 is widely regarded as one of Singapore’s most advanced premium digital locks, combining palm vein authentication, 3D AI facial recognition, fingerprint access, app control, and built-in Wi-Fi connectivity within a sleek curved architectural design.

Designed for modern Singapore homes, the Mercury X6 prioritises both security and everyday convenience through its fast biometric authentication, elegant minimalist profile and comprehensive smart access ecosystem.

Further enhanced by the Interlock Mercury Ecosystem™, the Mercury X6 supports advanced synchronised smart access capabilities when paired with compatible Mercury gate locks such as the Mercury G3.

Powered by Interlock’s Advanced Dual Synchronised Module™, compatible Mercury locks support coordinated two-way gate and door unlocking designed specifically around Singapore’s common dual-layer HDB living environment.

Unlike many standalone smart locks that focus purely on app features, the Mercury ecosystem also prioritises real-world installation compatibility, metal gate alignment, local installer support, and long-term serviceability for Singapore homeowners.

With premium biometric security, synchronised ecosystem access, emergency USB-C charging, and local after-sales support, the Interlock Mercury X6 stands out as one of Singapore’s most complete smart lock platforms in 2026.

The Interlock Mercury series is Singapore's best dedicated smart lock pick — from the entry-level X2 (fingerprint, PIN and card access, no app required) to the flagship X6 with palm vein and 3D facial recognition plus a built-in video intercom. See the full Interlock Mercury smart lock range

A smart door lock is an electromechanical lock with a built‑in computer that replaces a traditional keyed lock.

Instead of using a physical key, you can open it with a smartphone app, a PIN code, a fingerprint scan, or an access card. It lets you lock or unlock your door from anywhere, see who’s entered or left, and create temporary codes for visitors.

You can also connect it to other smart home devices—like cameras or voice assistants—for extra convenience and security.

A digital lock is any lock that uses electronic access methods — fingerprint, PIN, RFID card, or face recognition — instead of a physical key. A smart lock is a type of digital lock that also connects to your phone or home network via Wi-Fi or Bluetooth, allowing remote access, access logs, and smart home integration. All smart locks are digital locks, but not all digital locks are smart locks.
