Smart Lock Singapore - Trusted Smart Lock Specialists Since 2008

For most Singapore homeowners, yes — if you want remote access, push notifications, and guest PIN management. A digital lock is sufficient if you only need keyless entry without app features. The Interlock Mercury X2 is our digital-only option; the V6, X5, and X6 add full smart features. Contact us if you're unsure which suits your home.

Yes. All Interlock Mercury door locks are designed and tested for HDB main doors. We also offer synchronised door-and-gate bundles specifically for HDB homes with front gates. Our team does a door compatibility check before every installation.

A digital lock replaces your physical key with a fingerprint, PIN, or card — but operates offline with no internet connection. A smart lock does all of this and connects to your home Wi-Fi, enabling remote unlock via app, real-time door alerts, access logging, and smart home automation. All Interlock Mercury door locks (X5, V6, X6) are smart locks. The X2 is our standard digital lock for homeowners who prefer no app or connectivity.

Interlock Mercury is Singapore's most advanced smart digital door lock with 10-in-1 access methods including facial, palm vein recognition, RFID card, smartphone app, and mechanical key backup. Designed specifically for Singapore's climate with professional installation and local warranty support.

For HDB main doors, the Interlock Mercury X6 is the most complete option — palm vein + facial recognition, built-in viewer, two-way intercom and full app control. For HDB door + gate together, the Mercury bundle (X6 + G3 or V6 + G2) gives you both locks on one app.

Pick based on your priorities. X6 is best if you want the most complete “flagship” setup (premium biometrics + viewer experience + smart features). V6 suits families who want flagship security and convenience at a more value-led tier. X5 is ideal for multi-generation households where ease-of-use matters most. X2 fits buyers who want a simpler, budget-friendly digital lock without going heavy on smart features.

Yes, the Interlock Mercury digital door lock is fully compatible with HDB flats, condominiums, and landed properties. Our professional installation team ensures proper fitting to standard Singapore door preparation.

Core unlocking (biometrics, PIN, card, key—depending on model) works directly on the lock. Wi-Fi/app features are mainly for smart control like remote management, viewing activity history, and managing users or PIN types (feature availability depends on model). If you prefer a simpler setup, choose the Mercury X2, designed to be more “offline-first.”

Yes. Selected Mercury models support temporary/periodic PINs (time-limited access for helpers or visitors). The Mercury X6 also support one-time PINs, which are useful for deliveries or short visits. Choose a model based on how often you need to create and manage guest access.

Mercury locks are designed to reduce lockout risk with low-battery alerts and an emergency USB (USB-C) backup power option. If the battery runs out, you can use a power bank via the emergency port to power the lock temporarily and unlock.

Absolutely. The Interlock Mercury digital door lock is engineered and tested for Singapore's tropical climate with high humidity resistance. All electronic components are protected, ensuring reliable performance year-round with our local warranty coverage.

Interlock Mercury smart door lock comes with complimentary professional installation across Singapore. Our certified technicians handle the complete setup including lock removal of your old lock, installation, programming and user training at no additional cost.
