Why Choose Interlock Mercury?

At first glance, every brand looks premium. Here's what actually differentiates Mercury.

Palm Vein Recognition

Palm Vein Recognition

Scan the veins beneath your palm — no touch, spoof-proof, works even with wet hands. No other brand at this price offers this in Singapore.

3D Facial Recognition

3D Facial Recognition

Live body detection prevents photo or video spoofing. AI depth-mapping creates a 3D face signature. Works in the dark too.

Tuya Smart Ecosystem

Tuya Smart Ecosystem

It’s the ultimate "choose your own adventure" for smart homes, offering plug-and-play simplicity or deep local control for total privacy — no proprietary app lock-in.

4.5" HD Display Intercom

4.5" HD Display Intercom

See who's at your door — in HD — before you open it. Two-way voice. No separate doorbell needed. Crystal clear even at night.

Built for Singapore Homes

Built for Singapore Homes

Engineered for HDB gate + door configurations. Dual-sync unlocking means one authentication opens both. Competitors build for global markets — we build for yours.

Professional Install Included

Common Questions

Before you commit.

Can I try before I buy?

If you'd like a consultation first, WhatsApp us and we'll arrange a quick video walkthrough of the Interlock Mercury features so you can decide with confidence.

Alternatively, arrange an exclusive 1-1 by appointment only to experience the locks in real life. Contact us for appointment timeslots.

What does "installation included" actually mean?

One of our certified technicians visits your home, removes your old lock, installs the new Interlock Mercury, calibrates all biometric sensors (face, palm vein, fingerprint) to your family, sets up the Tuya Smart app, and gives you a walkthrough. Typically 2–3 hours. Wooden doors and Gate only at the base price — additional charge may apply for metal/glass.

What if my door isn't compatible?

Our technicians have installed on virtually every HDB, condo, and landed property door type in Singapore. When you book, share a photo of your door and gate — we'll confirm compatibility before your appointment. If there's any adjustment needed, we'll let you know the cost upfront with no surprises.

How is Interlock Mercury different from what's at the show?

Palm vein recognition is the clearest differentiator — it's contactless, spoof-proof, and available in Interlock Mercury at an affordable price. Combined with the 4.5" HD door viewer with two-way intercom (no separate doorbell needed) and Tuya open ecosystem, Mercury offers more for less when compared to what's on display at the booths this weekend.
