Interlock Singapore
Best Digital Gate Lock in Singapore 2026

Singapore homes with metal gates – especially many HDB flats, older condos, and some landed homes – need a digital gate lock that can handle outdoor exposure, support fast daily entry, and (ideally) give better awareness of visitors and parcels. This 2026 guide compares five focused options so you can choose based on your gate layout, household profile, and smart-home plans.

This guide is for:

  • HDB owners with a metal grill gate in front of a wooden door.
  • Condo owners with corridor or lift-lobby gates leading to their unit.
  • Landed or older apartment owners who want an installer-backed gate solution.
  • Households comparing camera gate locks, push-pull gate locks, and simple PIN/card models.

Quick verdict: 2026 winners by use-case

Best overall smart gate lock (security + visibility): Interlock Mercury G3
If you want the most complete “gate experience” – security plus visual awareness at the entrance – the Mercury G3 is positioned as a dual-camera smart gate lock engineered specifically for metal gates. It aims to combine modern access methods with a gate-mounted camera concept so you can see who is at the gate and what is happening near the floor/parcel area, instead of relying only on a separate CCTV.

Best value smart gate lock (camera + essentials): Interlock Mercury G2
The Mercury G2 is a value-tier smart gate lock designed for HDB and condo gates. It’s a strong everyday pick if you want biometrics and app-style convenience at your gate while staying in a more accessible price band.

Best for push-pull gate feel + smart-home direction: Solity G1
The Solity G1 stands out as a push-pull mortise smart gate lock with feature-rich access. It’s often considered when homeowners want a premium handle experience on the gate and plan to build around smart-home platforms over time (confirm exact integration support by the current kit/version).

Best for Apple ecosystem (door/gate after modification): Aqara U100
Aqara U100 is best known as a smart deadbolt with Apple Home / Home Key appeal. In Singapore, it can be considered for certain gate setups when installed correctly and when gate/door clearance allows (this is not a plug-and-play “standard gate lock” swap).

Best budget PIN + card gate lock (simple, no-fuss): Gateman G-Touch
The Gateman G-Touch is a straightforward, budget-friendly digital lock commonly used on Singapore doors and gates, focusing on PIN and RFID card access. It’s ideal for rentals, helpers’ rooms, and “keep it simple” families who don’t need apps or cameras.

What matters most for Singapore HDB & condo gates

  1. Gate format and installation fit
    Metal gates in Singapore vary a lot: bar spacing, frame thickness, lockcase position, and the distance between gate and main door. The “best” digital gate lock is the one that mounts neatly, lines up reliably with the strike, and does not create awkward gaps. If you’re unsure, follow a professional checklist via installation services and send gate photos before confirming a model.
  2. Outdoor resilience
    Gate locks sit closer to corridor humidity and rain drift than door locks. Prioritise models sold as gate locks (or locks proven in semi-exposed areas), and choose brands with clear local after-sales support. For add-ons like cards or replacement items, see add-ons & accessories.
  3. Daily entry speed (the family test)
    Every person who uses the gate – children, seniors, helpers, tenants – should be able to get through quickly and confidently. In practice this means reliable biometrics (where applicable), easy-to-use PIN pads, and consistent locking behaviour.
  4. Visibility and parcel checks (huge in 2026)
    If you get deliveries multiple times a week, camera-style gate locks can reduce “did they really come?” anxiety by making it easier to verify visitors and parcels. This is one reason many households compare Mercury G3 vs Mercury G2.
  5. Smart-home and ecosystem fit
    If you’re building around Apple Home, Google Home, or broader smart-home plans, check for explicit support rather than assuming “Wi-Fi” means deep integration. Apple Home Key is still rare in gate setups, which is why Aqara U100 gets attention (when installation conditions allow).
  6. User types and access methods
    Plan for how people actually unlock: some prefer fingerprint, some prefer PIN, and some want cards for helpers or short-term access. If you want “easy for everyone”, simple models like Gateman G-Touch stay popular.

1) Interlock Mercury G3 — Best overall digital gate lock (security + visibility)

Interlock Mercury G3 is positioned as a flagship dual-camera smart gate lock created for Singapore-style metal gates, rather than a door lock adapted for grills. It aims to combine modern access methods (biometric, PIN/card, app-style control – confirm exact specs by kit) with a dual-camera concept: an upper angle for visitors and a lower angle intended to monitor the floor or parcel area.

Best for:

  • HDB flats with frequent food/parcel deliveries (gate visibility matters).
  • Condo units with corridor or lobby gates where adding separate CCTV is hard.
  • Homeowners who want a “next-gen” gate experience, not just a keypad swap.

Pros:

  • Built and sold as a metal gate digital lock for Singapore layouts (see also the gate lock collection).
  • Visibility-first positioning with a dual-camera concept (confirm exact camera spec by kit/version).
  • Works naturally within the Interlock Mercury ecosystem.

Cons:

  • Higher tier than simple PIN/card models like Gateman G-Touch.
  • Feature set can vary by kit/version; confirm current specs before ordering.

Choose this if…
You want your gate to combine unlocking, visitor verification and parcel awareness in one flagship-style lock, and you’re okay investing more for visibility and a richer smart experience.

Best for:

  • First-time digital gate lock buyers moving from a mechanical gate lock.
  • HDB gate owners who want a strong upgrade while still watching overall renovation spend.
  • Condo owners who prioritise practicality and value over maximum spec.

Pros:

  • Built as a gate lock solution for Singapore metal gates (browse options in the digital gate lock collection).
  • Strong “everyday convenience” positioning without the highest flagship tier.

Cons:

  • Less visibility-first than Mercury G3.
  • Smart features can vary by kit/app version; confirm the bundle you’re buying.

4) Aqara U100 — Best for Apple Home Key households (door or modified gate)

FAQ

Can any digital lock be used on a metal gate?

No. Many digital locks are designed for wooden doors and may not fit or survive long‑term on a metal gate. For HDB and condo gates, you should use locks marketed as gate‑ready, or work with an installer who can modify the gate appropriately for specific models.

Is Aqara U100 really suitable for HDB gates?

Yes – but only with the right conditions. U100 is a deadbolt, so your gate needs enough clearance from the main door and may require drilling, a strike plate or a protective box. When those conditions are met, installers in Singapore do use Aqara U100 on HDB gates, and you get Apple Home Key at the gate.

Do I need a camera on my gate lock?

You do not need a camera, but if you receive frequent deliveries or live along a busy corridor, a camera or dual‑camera gate lock can significantly improve visibility. It helps you confirm visitors, check parcels and respond faster without walking to the door every time.

Can I sync my gate and door lock to open together?

Some ecosystems and bundles support paired or “dual‑sync” setups, where a gate lock and door lock can be controlled via the same app or automations. Whether they physically unlock together depends on the exact models, wiring and integrations, so you should confirm this when planning your setup.

Do digital gate locks still come with physical keys?

Most reputable models include a mechanical key override for emergencies such as electronics failure or completely drained batteries. It is a good idea to store at least one physical key in a safe place away from the gate.
