About Interlock Digital Lock Singapore | Smart Lock Specialists

Interlock has been Singapore's dedicated digital lock specialist since 2008, bringing 17 years of experience, expert guidance, certified in-house installation, and lifetime technical support to HDB, condo, and landed homes. The company doesn't use subcontractors, and has completed more than 15,000 installations with Singapore-based support.

Interlock's homegrown brand, Interlock Mercury, anchors its range with a lineup of smart door and gate locks featuring facial recognition, palm vein scanning, fingerprint access, and app-based control. Alongside its own brand, Interlock carries Aqara, Gateman (Assa Abloy/Irevo), Lockin, Solity, and Samsung Zigbang digital locks, giving customers a wide choice of biometric and smart access options.

The team helps homeowners choose the right setup for their specific property type — synchronised door-and-gate solutions for HDB flats, mortise and add-on rim locks for condos and apartments with shared corridors, or heavier-duty main door locks for landed properties. Beyond locks themselves, Interlock also offers repair and replacement services, professional installation, and accessories including batteries, door closers, door viewers, smart doorbells, and letterbox locks.

Interlock: Singapore's Digital Lock Specialist Since 2008

Interlock has spent 17 years as Singapore's dedicated digital lock specialist, having launched in 2008. Over that time, the company has completed more than 15,000 installations across HDB flats, condos, and landed homes, offering expert guidance, certified in-house installation, and lifetime technical support — all without relying on subcontractors.

A Homegrown Smart Lock Ecosystem

At the centre of Interlock's range is its own homegrown brand, Interlock Mercury. The Mercury ecosystem is built to help homeowners create a smoother, more secure entry experience across both the main door and front gate. The lineup includes the Interlock Mercury X6, recommended as the go-to HDB digital lock, combining AI-powered facial and palm vein recognition for hands-free entry, and the Interlock Mercury V6, recommended for condos, with 3D binocular face recognition, an HD door viewer, fingerprint and virtual-password access, USB-C emergency power, infrared night vision, and real-time push alerts.

Other Mercury models include the X5, designed for multi-generational households with facial recognition, palm vein scanning, PIN, fingerprint, and card access on a 4.5 inch touchscreen display; the X2, a fingerprint-access lock with no cloud storage; and on the gate side, the G4 DualKey — described as the world's first DualKey gate lock system — alongside the G3, with dual camera security for parcel and visitor viewing, and the G2, with facial recognition unlocking. For homes wanting synchronised access, the Interlock Mercury Door & Gate Lock Bundle lets the door and gate locks be configured to unlock simultaneously.

Beyond Interlock's Own Brand

Interlock also carries a curated range of other digital lock brands, including Aqara (owned by Lumi United Technology), Gateman (Korea's #1 digital lock brand, part of Assa Abloy/Irevo), Lockin (whose V5 Max is billed as the world's first palm vein recognition smart lock, alongside the finger vein push-pull Lockin S5), Solity (a premium Korean smart lock brand), and Samsung Zigbang, sold locally as an authorised Singapore seller.

Matched to Your Home Type

Interlock helps homeowners pick the right setup based on real Singapore home layouts. For HDB flats, the focus is on synchronised door-and-gate solutions that suit common layouts and daily family use, with the Interlock Mercury X6, Aqara A100, and Solity GM7000 among the HDB-compatible options. For condos and apartments, where main doors vary by development, Interlock handles mortise locks, add-on rim locks, and gate-only installs for shared corridors, with the Mercury V6 and Aqara D200i popular for their sleek profiles and smart home integration. For landed properties, where the gate typically runs on a separate access system, the focus shifts to the main door — with the Mercury X6 and Lockin V5 Max popular choices for the heavier doors common in these homes.

Full-Service Support

Beyond selling locks, Interlock offers repair and replacement services and professional installation, along with a full range of accessories: batteries, door closers, door viewers, a smart doorbell camera hub, and digital letterbox locks. The company also runs promotions, including discounts and a group buy option for digital locks.
