FAQ

What makes Interlock Mercury the best digital door lock in Singapore?

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.

What is the best Interlock Mercury model right now?

Interlock Mercury X6 is the top choice because it combines high-end biometric entry (including palm vein + facial recognition), a 4" indoor viewer, two-way intercom with in built camera, and app control with unlock history/monitoring.

How do I choose between Mercury X6, V6, X5, and X2 for my home?

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.

 Is the Interlock Mercury smart door lock suitable for HDB flats?

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.

Do Mercury locks need Wi-Fi to work, and which features require the app?

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.”

Do Interlock Mercury locks support guest access like one-time PINs and time-limited PINs?

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.

What happens if the battery is low or fully depleted? Can I still unlock the door?

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.

Can the Interlock Mercury smart lock withstand Singapore's humidity?

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.

How much does Interlock Mercury digital door lock installation cost?

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.
