Best Digital Lock Brands in Singapore (2026 Edition)

Best Overall Digital Lock Brand for HDB Door + Gate: Interlock Mercury

Interlock Mercury ranks as the best overall digital lock brand for many HDB households because it is built around Singapore’s most common entry setup: a wooden main door paired with a metal gate.

Many digital lock brands focus mainly on the door lock itself. Mercury is different because it treats the door and gate as one daily entry system. This matters for HDB homeowners because most families do not only unlock one layer. They unlock the gate, the door, and often need the whole setup to work smoothly together every day.

The biggest advantage is accountability. With Mercury, the lock, installation, calibration, door-gate pairing, and after-sales support are handled under one Interlock support path. This reduces the common problem where the lock seller, installer, app provider, and warranty contact are all separate parties.

Why Interlock Mercury Leads for HDB Homes

• Designed around door + metal gate setups: Useful for HDB flats where the gate is still part of the daily entry experience.
• Door–gate synchronisation options: Compatible Mercury door and gate locks can be paired for smoother daily unlocking.
• Installer-led accountability: One team handles installation, alignment, calibration, and post-sales support.
• Family-friendly access: Models in the Mercury range support options such as face recognition, palm vein, fingerprint, PIN, RFID, and app access depending on model.
• Better for multi-generation homes: Palm vein and face recognition can be useful when fingerprints are inconsistent for elderly users or children.

For homeowners who want a complete Singapore-focused digital lock solution instead of just a standalone lock, Mercury is the strongest recommendation.

Best for Smart Home Ecosystems: Aqara

Aqara is the strongest choice for homeowners who already care about smart-home automation. It is especially suitable for users who want their digital lock to work with a larger ecosystem involving sensors, hubs, lighting, curtains, cameras, and automations.

Aqara’s strength is not only the lock hardware. Its real advantage is ecosystem depth. For homeowners using Apple Home, Google Home, Matter-supported devices, or Aqara sensors, the lock can become part of a wider smart-home routine.

For example, unlocking the door can trigger lights, disable an alarm scene, or work together with other Aqara devices. This makes Aqara ideal for tech-forward homeowners who want more than basic fingerprint and PIN access.

The trade-off is that Aqara may not always be the most straightforward choice for every metal gate setup or every older HDB configuration. It is best for users who prioritise ecosystem integration and are comfortable managing smart-home devices.

Best Value-for-Money Digital Lock Brand: Gateman

Gateman is now our best value-for-money recommendation because value should not only mean the cheapest lock with the longest feature list. For digital locks, real value comes from reliability, durability, ease of use, and fewer problems over time.

Gateman locks are popular among homeowners who want a simple, proven, and stable lock without unnecessary app complexity. Many Gateman models focus on the basics: PIN, RFID card, mechanical reliability, and straightforward daily use.

This is why Gateman is a strong value pick for HDB and condo owners who do not need every advanced feature. If a lock can last for years, has fewer software dependencies, and is available at accessible price points, it can be better value than a more expensive lock with features the household rarely uses.

Why Gateman Is a Better Value Pick

• Reliability-first design: Gateman is known for simple, stable operation rather than chasing every new smart feature.
• Good for practical households: Suitable for users who want a lock that works daily with minimal fuss.
• Lower software dependency: Many Gateman models do not rely heavily on app or cloud features.
• Accessible pricing: Selected Gateman options are available at lower price points compared with many feature-heavy premium locks.
• Strong long-term value: A reliable lock that lasts longer can be better value than a more expensive lock with basic features.

Gateman is best for homeowners who prefer “set it and forget it” reliability over complex smart-home features.

Best for Push–Pull Digital Locks: Samsung / Zigbang

Samsung / Zigbang remains a familiar name for push–pull digital locks. For homeowners who like the convenience of pushing or pulling the handle instead of turning a lever, Samsung and Zigbang models are often one of the first brands they consider.

Push–pull locks are useful for families who often enter with groceries, bags, children, or items in hand. They feel intuitive and premium, especially on main wooden doors.

The main reason Samsung / Zigbang continues to appear in brand comparisons is familiarity. Many homeowners already know the brand from older Samsung door lock models, and the push–pull design remains a strong selling point.

The limitation is that Samsung / Zigbang may not always offer the most complete gate-and-door ecosystem for HDB homeowners compared with a purpose-built Mercury setup. It is best for users who specifically want push–pull ergonomics on the main door.

Best Premium Aesthetic Brand: Kaadas

Kaadas is best for homeowners who treat the entrance as part of the interior design. The brand is often considered by condo owners or design-conscious homeowners who want a sleeker and more premium-looking digital lock.

Kaadas models typically focus on slim profiles, refined finishes, and integrated biometric modules. For modern condo doors, where the lock appearance matters as much as the function, Kaadas can be a strong fit.

The trade-off is that Kaadas is not necessarily the strongest door-and-gate ecosystem brand for HDB flats. It is better positioned for homeowners who want a polished main door lock and are willing to pay more for design appeal.

Best Practical Korean Smart Lock Option: Solity

Solity remains a relevant digital lock brand in Singapore, but it is no longer our best value-for-money recommendation.

Solity can still be considered by homeowners who like Korean-style digital locks and want practical features such as app access, PIN, fingerprint, RFID, alarms, or logs depending on model. It can be a suitable option for users who like the brand’s design and feature mix.

However, compared with Gateman, Solity does not always feel like the stronger value pick when price, feature depth, and long-term reliability are considered together. Some models may feel relatively expensive for what they offer, especially when the household does not need every smart feature.

For this reason, Solity is better positioned as a practical Korean smart lock option rather than the top value choice.

Best for Rental Units and PIN Sharing: Igloohome

Igloohome is strongest for rental units, short-stay properties, and situations where owners need to issue temporary access without handing over physical keys.

Its main strength is offline PIN access. This allows property owners and managers to create time-sensitive access codes without requiring the lock itself to be constantly connected to Wi-Fi.

For landlords, hosts, and property managers, this can reduce coordination issues during guest check-ins, tenant turnover, servicing, or temporary contractor access.

For owner-occupied homes, however, Igloohome may not be the most complete choice if the priority is door-and-gate synchronisation, family biometrics, or smart-home ecosystem integration. It is best when rental access management is the main requirement.

1. Interlock — Mercury Series

Instead of focusing only on individual lock features, Mercury is built as a complete door-and-gate solution. Compatible Mercury locks can be paired through Interlock’s synchronised unlocking setup, giving homeowners a smoother daily experience across both entry layers.

This is especially useful for families who do not want to manage two unrelated brands, two different user experiences, or two separate support channels. With Mercury, Interlock manages the recommendation, installation, calibration, and after-sales support directly.

Mercury also fits modern household needs. Depending on the model selected, users can choose features such as palm vein, 3D facial recognition, fingerprint, PIN, RFID card, app access, remote viewing, gate camera functions, and door-gate pairing.

For elderly users or children, palm vein and face recognition can be especially practical because fingerprint recognition may not always be consistent. For HDB families, the wider Mercury ecosystem also helps keep the entry experience consistent between the door and gate.

Choose Interlock Mercury if: you want one complete, locally supported digital lock ecosystem for your HDB door and gate, with installer-led accountability and strong family-friendly access options.

2. Aqara

Aqara ranks second because it is the strongest choice for smart-home users. If your home already uses smart sensors, hubs, automations, Apple Home, Google Home, or Matter-supported devices, Aqara is one of the most logical brands to consider.

Aqara locks are not just standalone digital locks. They can become part of a larger smart-home flow, where unlocking the door triggers other devices or automations.

This makes Aqara especially suitable for homeowners who want a connected smart home rather than just a digital lock. It is also a strong fit for newer condo owners or tech-forward HDB homeowners who care about automation.

The main limitation is that Aqara may require more ecosystem understanding than simpler lock brands. It is also not always the most straightforward option if your main concern is metal gate compatibility or a unified door-and-gate support path.

Choose Aqara if: smart-home integration is your top priority and you want your digital lock to work together with sensors, hubs, and automations.

3. Gateman

Gateman moves up in this refreshed ranking because it deserves stronger recognition as the best value-for-money brand. For digital locks, value is not just about the number of features printed on the brochure. It is about whether the lock works reliably every day, lasts well, and causes fewer headaches over time.

Gateman is well suited for homeowners who prefer simple and proven locks. Many Gateman models focus on core access functions such as PIN and RFID card instead of heavy app dependency.

This makes Gateman a practical recommendation for households that do not need advanced features like facial recognition, palm vein, dual camera viewing, or deep smart-home automation.

Its appeal is simple: if a homeowner can get a reliable lock at a reasonable price, and that lock can serve the household for years with minimal fuss, that is strong real-world value.

Choose Gateman if: you want a reliable, simple, and practical digital lock with strong long-term value.

4. Samsung / Zigbang

Samsung / Zigbang remains one of the most recognisable digital lock names in Singapore, especially for push–pull main door locks.

The biggest reason to choose Samsung / Zigbang is ergonomics. Push–pull locks feel easy and natural to use, especially when entering with groceries, parcels, bags, or children.

The brand also benefits from familiarity. Many homeowners already know Samsung digital locks from older installations, and this familiarity still helps buyers feel confident.

However, Samsung / Zigbang is not necessarily the strongest choice if you want a complete HDB door-and-gate ecosystem. It is best for homeowners who already know they want a push–pull main door lock.

Choose Samsung / Zigbang if: push–pull convenience and brand familiarity matter more than a full door-and-gate ecosystem.

5. Kaadas

Kaadas ranks well for homeowners who care about aesthetics. It is especially relevant for modern condo doors, renovated homes, and buyers who want the digital lock to blend nicely with the entrance design.

The brand often appeals to users who want a more premium look and feel, with cleaner finishes and sleeker lock profiles compared with more utilitarian designs.

Kaadas can also offer strong biometric options depending on model, making it a good upgrade choice for homeowners moving away from older mechanical locks or basic digital locks.

Its limitation is that design appeal does not automatically make it the best choice for every HDB door-and-gate setup. For HDB families, compatibility and installer accountability may matter more than aesthetics alone.

Choose Kaadas if: you want a premium-looking digital lock for a modern main door or condo entrance.

6. Solity

Solity remains a recognised Korean digital lock brand in Singapore, but this refreshed guide no longer positions it as the best value-for-money choice.

The brand still has its place. Solity can suit homeowners who like Korean lock styling and want practical smart features, depending on the model selected. For some users, the combination of app access, PIN, fingerprint, RFID, alarms, and logs may be attractive.

However, compared with Gateman, Solity may not always deliver the strongest value when you weigh price, reliability, and actual daily feature usage. Some Solity models may feel expensive for relatively basic functions.

Solity is still worth considering, but it is better described as a practical Korean smart lock option rather than the top value pick.

Choose Solity if: you like Korean-style digital locks and want practical smart features, but do not necessarily need the most advanced ecosystem or the strongest value positioning.

7. Igloohome

Igloohome is a specialised brand rather than a general recommendation for every homeowner. Its strongest use case is rental access, guest access, and temporary PIN sharing.

The ability to issue time-bound PIN codes is useful for landlords, hosts, short-stay units, service apartments, and property managers. It reduces the need for physical key handovers and can make access management smoother.

For owner-occupied HDB or condo units, Igloohome may not be the first recommendation unless access sharing is a major priority. Families who care more about biometrics, gate synchronisation, or local installer-led support may prefer other brands.

Choose Igloohome if: you manage rental units, guest access, or temporary PIN sharing.
