What Defines the Best Digital Lock in Singapore (2026 Edition)

For 2026, the best digital locks in Singapore combine advanced security technologies—such as biometrics, smart cylinders and tamper alarms—with simple, reliable daily use. Homeowners increasingly expect smart features like app control, activity logs and facial or palm-vein recognition that remain safe and intuitive for children and elderly users. Door compatibility is equally crucial, as Singapore homes use a mix of HDB wooden doors, metal gates, glass doors and sliding doors, making engineered fit and dual-sync door-and-gate unlocking valuable. Pricing spans from entry-level offline models for BTOs and rentals to premium AI-enabled locks with video intercom and smart-home integration, while strong after-sales support, local servicing and reliable emergency power options (USB-C or 9V) remain essential in Singapore’s humid, high-rise environment.

Tip: If you are unsure about fit (thickness, clearance, existing holes), start with the decision framework below before comparing features.

What’s New in Digital Locks (2026 Trends That Actually Matter)

More interoperability expectations: homeowners increasingly want locks that sit cleanly inside a broader smart-home setup (instead of “yet another app”).

Faster, cleaner entry: contactless biometrics (face / palm-vein) reduce friction for kids, elderly, and families carrying parcels.

“Door intelligence” at the entrance: locks are increasingly doubling as visitor verification tools (viewer/intercom, alerts, logs) rather than just access devices.

Better onboarding and setup: the best experiences reduce setup friction, especially in multi-device homes (door + gate + room locks).

These trends are why the winners below are organised by door type and daily usability—not specs alone.


Best Digital Door Locks in Singapore 2026

Best Overall Digital Door Lock (Comprehensive): Interlock Mercury X6

Interlock Mercury X6 Smart Digital Door Lock with HD Door Viewer and Facial and Palm Vein Recognition. All new Singapore 2025.
"What digital lock do most Singaporeans recommend?"
Price: $899

Best for: families who want premium biometrics + a complete front-door experience (viewer/intercom, logs, app control) on HDB/condo/landed main doors.

The Interlock Mercury X6 is the best overall digital door lock for 2026 because it combines top-tier biometrics, video intercom, and smart-home integration in one slim, modern unit built for Singapore main doors. It offers palm vein recognition, 3D facial recognition, fingerprint, PIN, RFID card, mechanical key, app unlock and multi-combination modes, giving every family member a convenient, secure way to enter.

For homeowners who want a next-generation smart door experience, the X6 doubles as a 4.5-inch HD indoor viewer with real-time video intercom, so you can see and speak to visitors directly from the lock or via Tuya app. Its Class C smart lock cylinder, tamper resistance, fireproof and weather-resistant build, and magnetic interference resistance make it well suited to HDB, condo and landed properties, including high-rise units.

The X6 is designed to fit common Singapore doors with a slim 19 mm profile and supports typical door thicknesses from about 40–120 mm, making installation practical for many flats and homes. With rechargeable lithium batteries, USB-C emergency power, auto-locking, visitor unlock records and multi-language voice prompts, it delivers a comprehensive, premium experience for busy modern households.

Most Affordable Digital Door Lock: Interlock Mercury X2

Interlock Mercury X2 | Simple, Cheap and Elegant

"Which digital lock is good and not overpriced in Singapore?"

Price: $499

Best for: BTO owners, rentals, and elderly-friendly households who want simple fingerprint/PIN access without apps or Wi-Fi.

The Interlock Mercury X2 is the most budget-friendly digital lock for homeowners, especially for BTOs or rental units. It focuses on core essentials without the complexity of apps or Wi-Fi. It offers 4-in-1 access via fingerprint, PIN code, RFID card, and mechanical key, with all data stored locally inside the lock instead of in the cloud, appealing to privacy-conscious or non-tech-savvy users.

Because the Mercury X2 runs on four standard AA batteries with long-lasting performance, there is no need for frequent charging or power banks, and visual/audio low-battery alerts make maintenance simple. Auto-lock and double-lock modes help ensure the door is secured after every entry, while an emergency USB-C port and mechanical key backup reduce the risk of lockouts.

For BTO owners, landlords and tenants, the X2’s aluminium construction, ergonomic handle with integrated fingerprint sensor, and straightforward on-lock registration of fingerprints and PINs make it a practical, affordable upgrade from traditional keys. Its compatibility with HDB, condo and landed doors (when matched correctly to door type and thickness) makes it a versatile choice for cost-conscious Singapore households.

Honourable Mention 1: Lockin S5

The Interlock Mercury G3 is the best overall digital gate lock for Singapore in 2026 because it is built around real corridor-gate needs: dual camera coverage for better visitor + parcel visibility, plus smart alerts and access logs for daily accountability. It is designed for typical Singapore metal gates and supports modern unlocking methods so families can enter quickly without sacrificing security.

If you want “gate intelligence” without installing separate CCTV, the G3’s dual-camera approach is its standout advantage—especially for deliveries where items are placed near the floor. Combined with the wider Mercury ecosystem, it also fits naturally into door + gate setups where you want a smoother entry flow (dual sync is a given in this tier).


Most Affordable Digital Gate Lock: Interlock Mercury G2

Interlock Mercury G2 Smart Gate Lock, all new in Singapore 2025

Designed specifically around HDB and typical metal gate layouts, it uses facial recognition with a wide-angle HD camera for quick, contactless access in varied lighting, along with fingerprint, PIN, card and mechanical key backup.

This makes the Mercury G2 an excellent “first digital gate lock” for BTO buyers, young families and landlords who want serious security without paying flagship prices. With its 4200 mAh rechargeable battery, USB-C emergency charging, glow-in-the-dark PIN keys, pry-proof alarm, auto-lock, night-vision camera and anti-peep virtual password, it balances affordability with the kind of advanced features usually reserved for higher-tier models.

Honourable Mention: Solity G1

Solity G1 Smart AI Gate Lock for Singapore Homes

Price: $799

The Solity G1 is an excellent honourable mention for homeowners who prefer a push-pull mortise design and deep smart-home integration at the gate. Designed for HDB metal gates, it replaces the original handle with a sleek push-pull mechanism and supports AI-driven 3D facial recognition, fingerprint, PIN, RFID card, mechanical key, Bluetooth, Wi-Fi and Matter-enabled app control.

For families who want hands-free entry at the gate, the G1 supports facial recognition, fingerprint, PIN, RFID card, mechanical key, Bluetooth, Wi-Fi or Matter-enabled app control, and can store up to 100 fingerprints and 100 RFID cards.

Best for: Singapore homes with a main wooden door + metal gate that want a single ecosystem and the most complete front-entrance setup (door intelligence + gate awareness).

The Interlock Mercury X6 + Mercury G3 bundle is the primary “best overall” choice for Singapore because it pairs a premium main-door experience (biometrics + viewer/intercom + logs) with a gate built for real corridor needs—especially Dual Camera visibility at the gate. In daily use, a matched ecosystem reduces friction (setup, users, troubleshooting) compared to mixing brands.

For busy families, the bundle supports paired unlocking (dual sync is a given in this tier), so moving from gate to main door feels smooth—especially when carrying groceries, handling deliveries, or coming home with kids.

Interlock Mercury V6 + G2 Door & Gate Lock Bundle

Price: Check live bundle price on product page (promos may change)

Best for: households that want a door+gate setup with strong daily security and smarter access—but prefer a more cost-controlled tier than flagship bundles.

This value tier is ideal when you want the benefits of an ecosystem (consistent user logic, smoother support, less setup confusion) while keeping the overall spend tighter. It is also a practical “first bundle” path for BTO owners and families standardising access for multiple users.

Honourable Mention Bundle: Solity GEA1000K + Solity G1

Solity G1+ GEA1000K Bundle

For Singapore homes that require fire-rated main-door locks, the GEA1000K is fire-rated and SCDF-approved, making it suitable for HDB, BTO and private housing where compliance is critical. Matter-ready smart-home integration, multi-method biometrics, forced-lock and anti-theft alarms, and emergency power options make this bundle a future-proof choice for tech-forward families.

Built for 12 mm glass panels and compatible with single or double glass door configurations, it provides flexibility across many commercial layouts, with local servicing in Singapore.

Interlock Mercury Sliding Door digital Lock. Best sliding door lock in the market

Price: $528

It supports fast fingerprint unlocking in under one second, app-based Bluetooth control, visitor logs, and temporary or timed PIN codes for guests or co-living situations.

For Singapore homes, the SD1’s precision fit for sliding doors, auto-lock function, tamper alarm, and long battery life (up to about 12 months on a set of AA batteries) make it highly practical. A USB-C emergency power port and mechanical key backup ensure access even in low-battery scenarios, while silent mode suits high-density apartments where noise at night is a concern.

Most Affordable Sliding Door Lock: Gateman G-Touch

Gateman G Touch: Simple Digital Lock with Card

Price: $368
The Gateman G-Touch is a cost-effective digital lock suited for room doors, smaller storage doors, and certain sliding setups where pin-and-card convenience is sufficient.

Its robust build and Korean manufacturing make it appealing for small businesses and tenanted premises that require basic but reliable digital access.


Quick Decision Helper (60-second match)

If you have a main wooden door + metal gate: start with a bundle (X6 + G3 or V6 + G2) to avoid mixed ecosystems.

If you want “no app, no fuss”: choose an offline-focused door lock (Mercury X2).

If you have kids/elderly and want the least friction: prioritise contactless entry (face/palm-vein) and clear daily usability (X6, G3).

If it’s a glass door: pick a glass-specific model (GD1 / MDL-280F), not a generic handle lock.

If it’s a sliding door: pick a dedicated sliding model (SD1) so the latch/clearance works correctly.

If you’re still unsure, the next section explains the measurements and constraints that usually cause installation issues in Singapore.

How to Choose the Right Digital Lock for Your Home in 2026

Choosing the right digital lock starts with your door or gate type and any regulatory requirements, then moves to user needs and smart features. A simple decision framework can help Singapore homeowners narrow down options quickly.

For fire-rated main doors in HDB or BTO flats, ensure the chosen lock and installation method do not compromise fire-rating requirements; fire-rated models like the Solity GEA1000K are specifically designed for such doors. If you have elderly family members or young children, prioritise locks with easy, contactless biometrics such as facial or palm-vein recognition on models like Interlock Mercury X6, Mercury G2 or Solity G1.

Homes with narrow metal gates or tight door–gate spacing should look at gate locks and bundles designed for HDB gates, such as Solity G1, Mercury G2, or coordinated bundles like X6 + G2 and GEA1000K + G1. For sliding or glass doors, avoid generic locks and instead select purpose-built models like Interlock Mercury GD1, Milre MDL-280F, or Mercury SD1 that match glass thickness and sliding clearances.

If you prefer offline security or have low-tech users, a lock like Interlock Mercury X2 provides digital convenience without Wi-Fi, cloud accounts, or apps, which can be ideal for rental units or elderly occupants. Smart-home enthusiasts and those wanting remote unlock, logs, and integration with Apple Home, Google Home, or Matter should consider models such as Interlock X6, Mercury G2, Aqara U100, or the Solity bundles with Matter compatibility.

Why Installation & After-Sales Support Matter in Singapore

In Singapore, many “digital lock problems” are actually door-fit problems: metal-gate alignment, clearance constraints, existing hole patterns, and high-use wear in humid conditions. That is why a lock that looks good on paper can still feel unreliable if installation is not properly matched to the door/gate.

Fit-first checks: door thickness, frame/handle clearance, and whether your existing lock cut-out can be reused cleanly.

Gate reality: gate spacing and latch alignment affect whether auto-lock and dual-sync feel smooth daily.

Post-install help: workmanship warranty, usage training (PINs/biometrics), and responsive troubleshooting reduce long-term friction.
