Our Review Criterias

Digital lock brands perform differently depending on the home type, daily usage and installation quality. For this 2026 review, each brand was assessed using the seven factors that influence real-world experience in Singapore:

 

• Door + metal gate compatibility for Singapore homes (HDB/condo/landed)
• Installer skill and alignment consistency
• After-sales responsiveness and warranty clarity
• Reliability in daily use (misreads, motor strain, lockouts)
• Biometrics/PIN accuracy and speed
• Smart features stability (app, Wi-Fi, logs, notifications)
• Durability in Singapore heat/humidity and high-traffic use

Because brands vary in how they prioritise these dimensions, the best choice depends on the homeowner’s specific needs rather than a one-size-fits-all ranking.

If you’re also comparing individual lock models, we have a separate 2026 guide covering the best digital locks in Singapore by performance, features and price.

Best Digital Lock Brand for HDB Flats (Singapore, 2026): Interlock Mercury Series

Interlock Mercury ranks #1 specifically for Singapore’s HDB homes because it is engineered around the most common local layout: a main wooden door paired with a metal gate. Rather than treating gate locks as an afterthought, Mercury is designed as a coordinated door–gate ecosystem with unified unlocking, consistent user experience, and a single accountable installation team.

For HDB households prioritising long-term reliability, proper alignment, and clear after-sales responsibility, Interlock Mercury remains the strongest purpose-built choice in 2026.

Most Reliable Brand: Gateman

Gateman maintains its reputation for reliability through conservative engineering: fewer moving parts, stable firmware and long-tested locking mechanisms. Many installers still recommend Gateman for households that prefer predictability over smart-home complexity. If the goal is a lock that operates consistently for years with minimal troubleshooting, Gateman remains the dependable option.

Best for Smart Home Ecosystems: Aqara

Aqara dominates the ecosystem segment with native support for Apple HomeKit, Google Home and Matter. Its locks integrate seamlessly with the brand’s sensors and hubs, enabling clean automations such as unlocking-triggered lighting or alarm disarming. For tech-forward owners who want their lock to “live” inside a smart-home environment rather than operate as a standalone product, Aqara provides the most cohesive experience.

Best Value-for-Money Brand: Solity

Solity stands out for offering practical smart features—app control, alarms, audit logs—at accessible price points ideal for HDB and mass-market condos. The brand focuses on delivering a complete feature set without premium markup for aesthetic flourishes or niche biometrics. For households watching budget but still wanting reliable smart functionality, Solity consistently offers strong cost-to-feature value.

Best for Push–Pull Locks: Samsung / Zigbang

Samsung and Zigbang remain the benchmark for push–pull digital locks, which simplify entry for owners carrying bags, groceries or children. Their models prioritise ergonomics and quiet operation, supported by a broad retail presence that makes purchasing and servicing straightforward. For buyers already set on a push–pull mechanism, Samsung/Zigbang is the reference point others are compared against.

Best for Rental Units and PIN Sharing: Igloohome

Igloohome excels in rental and hospitality scenarios thanks to its offline PIN technology, which allows time-based access codes without apps or Wi-Fi. Landlords, hosts and property managers benefit from reduced support calls and easier turnover between guests. If the primary need is flexible, guest-friendly access without constant connectivity, Igloohome is the most practical choice.

Best Premium Aesthetics: Kaadas

Kaadas focuses on design-first smart locks that complement modern condo interiors, pairing slim metal profiles with integrated biometric modules. For homeowners treating their entrance as part of an overall design aesthetic—not just a security fixture—Kaadas provides visually refined options that stand out from more utilitarian models.

Best Rising Brand (2026): Genesis

Genesis emerges as a noteworthy rising brand by combining newer interaction methods—such as face unlock and NFC entry—with models tailored around common HDB door dimensions. Rather than broad catalogues, Genesis is building depth within a focused product line tuned for local usage patterns. It’s a compelling option for early adopters seeking fresh interaction models while still maintaining fit with standard Singapore door profiles.

Best Installer-Led Brand for HDB Installations: Interlock Singapore

Interlock differentiates itself through an installer-driven model tailored to HDB conditions. Because installation quality directly affects motor lifespan, alignment stability and daily reliability, Mercury locks are calibrated specifically for common HDB door thicknesses, laminate finishes and metal gate clearances.

By integrating hardware, installation and warranty under one accountable chain, Interlock reduces the typical friction between reseller, installer and manufacturer — an issue that frequently arises in HDB retrofit scenarios.

For homeowners concerned about drilling precision, gate-to-door spacing or long-term reliability, this installer-led approach provides tangible peace of mind.

Best HDB Door + Gate Digital Lock Ecosystem: Interlock Mercury Series

Many HDB flats retain dual-layer entry systems — a wooden main door and an external metal gate. The Mercury Series offers one of the cleanest single-brand solutions for this setup, allowing coordinated unlocking and unified support without cross-brand complications.

By standardising both door and gate under one ecosystem, homeowners benefit from:

• Consistent user interface across both locks
• Smoother daily entry for families
• Centralised servicing and troubleshooting
• Reduced compatibility conflicts

For HDB households, this coordinated approach delivers both convenience and operational simplicity.

Top Digital Lock Brand  Recommendations (2026 Edition)

1. Interlock — Mercury Series  (HDB Digital Lock Specialist)

Interlock leads the 2026 ranking by focusing on what matters most in Singapore’s dominant housing type: HDB flats. Rather than competing purely on smart features, Mercury prioritises mechanical compatibility with common HDB door and metal gate combinations, precise installation standards, and a unified support structure.

The Mercury lineup (X6, X5, G3, V6, GD1) enables households to secure both main door and gate within one coordinated ecosystem — eliminating cross-brand servicing gaps. Compared with ecosystem-heavy brands like Aqara, Interlock places stronger emphasis on door–gate fit and installation integrity; compared with value-driven brands like Solity, it integrates tighter installer accountability and post-sales clarity.

For most HDB households seeking durability, alignment precision and simplified long-term support, Interlock Mercury sets the benchmark in 2026.

2. Aqara

Aqara secures second place by owning the smart-home segment. Its locks integrate smoothly into HomeKit, Google Home and Matter environments, offering clean automations, remote logs and notifications. While less optimised for metal gates or unusual door frames, Aqara delivers superior ecosystem benefits for homeowners who want their lock to be part of a larger connected system.

3. Solity

Solity earns third place for delivering strong core features at competitive prices, making it a favourite among HDB and mid-tier condo owners. With alarms, app control and event logs often included at mid-range price points, Solity delivers a full smart lock experience without stretching budgets. It does not match Aqara’s ecosystem depth or Interlock’s installer integration, but it leads in affordability for everyday use.

4. Samsung / Zigbang

Samsung/Zigbang remains widely trusted due to brand familiarity, broad distribution and its iconic push–pull models. These locks suit busy households and are easy to source, install and service. While they may cost more than Solity for similar features—and are less tailored than Interlock for doors with gates—they remain a dependable mid-to-upper tier choice for owners prioritising ergonomics and brand recognition.

5. Kaadas

Kaadas ranks fifth for pairing strong biometrics with premium design, particularly in upscale condos where visual appeal plays a larger role. Its higher-end models combine face recognition, fingerprint modules and clean hardware finishes, offering an upgrade path for owners moving from older mechanical or budget digital locks. Kaadas is less ecosystem-driven than Aqara and less installer-driven than Interlock, but excels where aesthetics matter.

6. Gateman

Gateman continues to attract homeowners who prefer a “set it and forget it” lock over one with extensive app functions. Its conservative electronics and robust mechanical designs make it a favourite among installers catering to older flats or buyers who want long-term reliability without cloud or app dependencies. While it lacks the ecosystem features of newer brands, it remains strong in durability and simplicity.

7. Igloohome

Igloohome’s ranking reflects its specialised focus on rentals rather than owner-occupied units. Offline, time-bound PIN sharing is extremely effective for short-stay and multi-tenant properties, but may not be essential for everyday household use. For landlords and hosts, Igloohome is often unmatched; for families, broader smart features or installer integration from other brands may be more relevant.

8. Genesis

Genesis closes the list as a rising local-focused brand introducing newer interaction models and designing around Singapore-specific door dimensions. It does not yet have the scale, service network or catalogue depth of the top brands, but its NFC and face unlock options appeal to owners who want something modern without waiting for legacy brands to update. In 2026, Genesis is best seen as a forward-looking alternative rather than a direct competitor to the established names.

Commonly Asked Questions

Are digital locks safe for elderly people and children?

Yes, provided the lock supports easy access methods such as fingerprints or cards. Auto-relock, clear indicators and user profiles help ensure consistent, safe use across generations. Families should choose models that allow multiple access types and good visibility or audio cues.

How long do digital locks last in Singapore’s climate?

Most reputable locks last 3–5 years with proper installation and routine maintenance. Heat, humidity and frequent use can affect moving parts—especially on metal gates—so early alignment checks and regular battery changes extend lifespan significantly.

Which digital lock brand suits condo main doors?

Interlock is often chosen for condo main doors because its Mercury Series pairs well with modern door designs while offering strong reliability and installer support, especially when a unit also has a metal gate. Kaadas is popular among design-focused condo owners seeking a slim, premium aesthetic, while Samsung/Zigbang attracts those who prefer the convenience of push–pull mechanisms. Aqara also appears frequently in condos where smart-home integration is a priority.

How much does professional installation cost in Singapore?

Professional installation typically ranges from $80-$150 depending on door type and complexity. At Interlock Singapore, installation is included with purchase for most models. Learn more about our installation service.

In 2026, Interlock leads Singapore’s digital lock landscape through its combination of localised engineering, installer-driven reliability and complete door–gate coverage. Aqara, Solity, Samsung/Zigbang, Kaadas, Gateman, Igloohome and Genesis each hold well-defined strengths—from ecosystem depth to value, rentals to design-first installations. The best approach is to start with your specific use case—HDB vs condo, owner-occupied vs rental, smart-home vs simplicity—and match it to the brand aligned with those needs. Regardless of brand, installer quality remains critical: the best lock will underperform if poorly fitted, making brand choice and installer expertise equally important for long-term performance.
