The U100's sealed keypad and corrosion-resistant hardware are built with that outdoor duty cycle in mind, rather than being an indoor lock adapted after the fact.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003eThe U100 gives you six distinct ways in, so every member of the household can use whichever suits them:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFingerprint\u003c\/strong\u003e – a 3D semiconductor sensor reads your print in about half a second, rated at 98.6% accuracy.

In practical terms, that's the difference between a lock that survives a Singapore thunderstorm and one that starts misbehaving after its first monsoon season — and it's the reason this lock can be installed on an exposed HDB gate, not just a sheltered front door.\u003c\/p\u003e\n\u003ch2\u003eSecurity \u0026amp; Auto-Lock\u003c\/h2\u003e\n\u003cp\u003eThe lock meets BHMA Level 3 security standards — the same grading system used to rate conventional mechanical deadbolts on resistance to forced entry, kicking and drilling — paired with a proper deadbolt mechanism rather than a lighter-duty latch. A built-in gyroscope senses when the door or gate has physically closed, engaging the deadbolt automatically so you're never left wondering, halfway down the corridor, whether you actually locked up.\u003c\/p\u003e\n\u003ch2\u003eBattery \u0026amp; Power\u003c\/h2\u003e\n\u003cp\u003eFour standard AA batteries power the lock for up to 8 months of typical use — batteries you can buy at any convenience store, rather than a proprietary rechargeable pack you have to order in. Advance low-battery notifications are sent to your phone well before the lock actually dies, and if the batteries ever do run flat completely, a USB-C emergency port on the exterior lets you power the lock temporarily with any phone power bank to get back in.\u003c\/p\u003e\n\u003ch2\u003eSmart Home Integration\u003c\/h2\u003e\n\u003cp\u003eThe included Aqara Hub (an E1 hub, bundled with every U100) connects the lock to Apple HomeKit, Google Home, Amazon Alexa and IFTTT, so unlocking the door can trigger hallway lights, adjust air-con, or switch security cameras to \"home\" mode as part of a wider automation routine — useful whether you're building out a full smart home or just want the porch light to come on automatically when you walk in.\u003c\/p\u003e\n\u003ch2\u003eInstalling on a Gate\u003c\/h2\u003e\n\u003cp\u003eGate installations can require a metal gate with a thicker shaft, or minor modification, to fit the deadbolt mechanism properly — most standard HDB gates have shafts that are too thin as-is.

It's built for households that want a genuinely touchless, hands-full-of-groceries entry experience without giving up backup options for the days that technology doesn't cooperate.\u003c\/p\u003e\n\u003ch2\u003eHow the Face Recognition Actually Works\u003c\/h2\u003e\n\u003cp\u003eMost budget \"facial recognition\" locks use a simple 2D camera, which can sometimes be fooled by a printed photo held up to the lens. The D200i instead uses Aqara's own structured-light 3D mapping — the same underlying approach as Face ID on an iPhone — projecting a pattern onto your face and measuring its depth and contours rather than just comparing a flat image. That's what lets it unlock in about a second while still being meaningfully harder to spoof than a 2D system, and it continues to work reliably in the dark, since it doesn't depend on visible-light photography. A generously large recognition zone, roughly 1.3–2.0m from the door, also solves a problem plain fingerprint locks struggle with: a child's faint, not-yet-defined fingerprint, or an elderly parent's fingerprint worn smooth by age, both scan just as reliably as anyone else's face.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003eSix access methods in total, covering biometric, digital and physical entry:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3D face recognition\u003c\/strong\u003e – unlocks in about a second using structured-light facial mapping, distinct from a simple 2D camera and far harder to fool with a photo.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApple Home Key\u003c\/strong\u003e – tap your iPhone or Apple Watch via NFC, no need to unlock your phone first.

Just as importantly for a face-scanning device: your facial data is processed and stored locally on the lock itself, never uploaded to any cloud server. That matters twice over — it means there's no remote database of your family's faces for anyone to breach, and it keeps the lock in line with Singapore's Personal Data Protection Act (PDPA).\u003c\/p\u003e\n\u003ch2\u003eBattery \u0026amp; Power\u003c\/h2\u003e\n\u003cp\u003eA rechargeable lithium battery lasts around 4 months per charge — shorter than a simple keypad lock, which is the trade-off for running a camera and face-mapping processor. To offset that, every D200i we sell includes a bonus second battery (worth $80), so you can swap in a fully charged spare in about thirty seconds and recharge the first one at your leisure, rather than the lock ever being out of action while you wait for it to charge. And if both batteries ever run out at once, the door still opens with the included mechanical key, or with a quick top-up from a power bank via the USB-C port.\u003c\/p\u003e\n\u003ch2\u003eSmart Home \u0026amp; Doorbell\u003c\/h2\u003e\n\u003cp\u003eThe D200i integrates with Apple HomeKit and Google Home, and includes a built-in doorbell button on the exterior panel that pushes a notification straight to your phone through the Aqara app when someone presses it — one less separate doorbell device to install and wire up. Paired with other Aqara smart home devices, walking in the door can trigger the lights to switch on and the air-con to adjust automatically, while leaving can arm your cameras and switch off appliances you've designated — no extra button presses required.\u003c\/p\u003e\n","brand":"Aqara","offers":[{"title":"Default Title","offer_id":41098560569440,"sku":"","price":1059.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4182\/6400\/files\/AqaraD200ICover.webp?v=1776166382"},{"product_id":"aqara-a100","title":"Aqara A100 Smart Door Lock","description":"\n\u003ch2\u003eA Straightforward, Well-Built Everyday Smart Lock\u003c\/h2\u003e\n\u003cp\u003eThe Aqara A100 focuses on doing the fundamentals well: a fast handle-mounted fingerprint scanner, six ways to get in, and genuine multi-point locking, all backed by Apple HomeKit and Google\/Alexa support. If the D100 and D200i are about adding new capabilities like cameras and face recognition, the A100 is about making the everyday basics — unlocking the door, securing it properly, and not running out of battery — as reliable as possible.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003eSix access methods are supported: fingerprint, PIN code (permanent, one-time or periodic), NFC tag, mechanical key, the Aqara app, and Apple Home Key — giving every household member and every situation (deliveries, cleaners, guests) an appropriate access method. A one-time password that expires after a single use is ideal for a delivery or a repairman who only needs access once; a periodic password that only works on, say, Tuesday mornings suits a weekly cleaner without you needing to remember to disable it afterwards.\u003c\/p\u003e\n\u003ch2\u003eInstant, One-Motion Entry\u003c\/h2\u003e\n\u003cp\u003eThe fingerprint reader sits right in the handle: a roughly 0.3-second scan and a roughly 0.5-second unlocking cylinder mean the whole sequence, from touch to open, happens in under a second and in a single natural motion — you're not standing at a separate keypad waiting before you can even reach for the handle. Apple Home Key works the same way for iPhone and Apple Watch owners: hold your device near the lock for an instant tap-to-unlock in Express Mode, or switch to a more secure mode that requires Face ID or a passcode first.\u003c\/p\u003e\n\u003ch2\u003eMulti-Point Locking\u003c\/h2\u003e\n\u003cp\u003eLifting the handle engages every bolt in the door simultaneously — one door bolt, three main lock bolts and a master lock bolt — rather than relying on a single latch or a single deadbolt point. This is the same principle behind traditional multi-point mortise locks used on higher-security doors: more engagement points along the door frame means more resistance to prying or forcing the door at any single weak spot, which is a meaningfully different security proposition to a basic single-bolt smart lock. Damage sensors on the front panel flag tampering attempts, and the lock includes electromagnetic shielding against the kind of signal-interference attacks that can trip up less protected electronic locks.\u003c\/p\u003e\n\u003ch2\u003eFire-Rated for HDB Doors\u003c\/h2\u003e\n\u003cp\u003eThe A100 is fire-rated and suitable for installation on HDB fire-rated doors, so upgrading to a smart lock doesn't put you out of compliance with local building requirements — a real concern in Singapore, where many HDB main doors carry a fire-rating that certain hardware modifications can compromise if you're not careful about what you install.\u003c\/p\u003e\n\u003ch2\u003eBattery \u0026amp; Power\u003c\/h2\u003e\n\u003cp\u003eEight AA batteries deliver up to 18 months of battery life on typical daily use — among the longest runtimes in the Aqara lineup, since the A100 doesn't need to power a screen, camera or rechargeable pack the way the camera-equipped models do. In practice that means you're looking at roughly one battery change every year and a half rather than every few months, which matters if you'd rather not think about the lock at all once it's installed.

It's built around a real BHMA-certified deadbolt, not a smart add-on bolted to a lighter-duty mechanism, which matters if you want the convenience of a hands-free lock without giving up the physical security of a proper deadbolt.\u003c\/p\u003e\n\u003ch2\u003eWhy UWB Instead of Bluetooth\u003c\/h2\u003e\n\u003cp\u003eBluetooth-based hands-free locks struggle to tell how far away your phone actually is — Bluetooth signal strength is a rough proxy for distance at best, which can cause accidental unlocks when you're simply walking past the house, or leave the lock vulnerable to relay attacks where someone amplifies the signal from a distance. UWB is a fundamentally different radio technology that measures both direction and distance precisely, in centimetres rather than a rough signal-strength guess, so the lock only engages when you're genuinely approaching the door with an authorised device in hand.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003eBeyond UWB hands-free entry: Apple Home Key (tap to unlock), fingerprint (stores up to 50), keypad PIN codes (including one-time and scheduled codes for guests, cleaners or Airbnb stays), NFC cards or tags, app control, and a physical key override for the times you'd simply rather use a key.\u003c\/p\u003e\n\u003ch2\u003eReal Deadbolt Hardware\u003c\/h2\u003e\n\u003cp\u003eThe U400 replaces a traditional deadbolt with BHMA-certified hardware — the same physical security standard used to grade conventional mechanical deadbolts on resistance to prying, drilling and forced entry — so you're getting genuine intrusion resistance, not just smart features layered onto a weaker mechanism underneath.\u003c\/p\u003e\n\u003ch2\u003eSmart Home Integration\u003c\/h2\u003e\n\u003cp\u003eMatter over Thread support means the U400 works natively with Apple Home, Alexa, Google Home, SmartThings and Home Assistant, and it can link with Aqara cameras and hubs to trigger lights or scenes whenever the door unlocks — arriving home can mean the porch light, the air-con and the security camera's \"home\" mode all activate together, without you touching anything else.\u003c\/p\u003e\n\u003ch2\u003eWeatherproofing \u0026amp; Power\u003c\/h2\u003e\n\u003cp\u003eThe exterior unit is IP65-rated for outdoor doors and gates, powered by a rechargeable battery with USB-C emergency charging as backup if it ever runs flat.\u003c\/p\u003e\n","brand":"Aqara","offers":[{"title":"Door","offer_id":42735272951904,"sku":null,"price":649.0,"currency_code":"SGD","in_stock":true},{"title":"Gate (Gate Modification required)","offer_id":42735272984672,"sku":null,"price":849.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4182\/6400\/files\/Aqara_Smart_Lock_u400_2.jpg?v=1767887070"},{"product_id":"aqara-u500-smart-rim-lock","title":"Aqara U500 Smart Rim Lock","description":"\n\u003ch2\u003eA No-Mortise Smart Lock for Wooden and Metal Doors\u003c\/h2\u003e\n\u003cp\u003eThe Aqara U500 Smart Rim Lock mounts onto your existing wooden or metal door without any mortise replacement, giving you a full smart-lock upgrade without altering the door itself — a meaningfully lower-disruption installation than locks that require cutting into the door's structure.\u003c\/p\u003e\n\u003ch2\u003eWays to Unlock\u003c\/h2\u003e\n\u003cp\u003eFingerprint, PIN code, NFC card, Apple Home Key, the Aqara and Matter apps, voice control, and a mechanical key backup — seven ways in, with remote unlock available through a compatible hub.\u003c\/p\u003e\n\u003ch2\u003eMatter over Thread\u003c\/h2\u003e\n\u003cp\u003eMatter over Thread support connects the U500 natively to Google Home, Apple Home, Alexa and SmartThings, with a gyroscope-based sensor that detects the door's open\/closed status for reliable auto-locking rather than relying on a timer alone.\u003c\/p\u003e\n\u003ch2\u003eAccess Management \u0026amp; Alerts\u003c\/h2\u003e\n\u003cp\u003eSet temporary or scheduled PINs for guests and helpers, enable Do Not Disturb or Away mode for privacy or travel, and review unlock history and activity logs through the app. Low-battery alerts and OTA firmware updates keep the lock current without manual intervention.\u003c\/p\u003e\n\u003ch2\u003eBuild \u0026amp; Power\u003c\/h2\u003e\n\u003cp\u003eAluminium alloy construction with an IP65-rated exterior panel, a mechanical key backup, and an emergency Type-C power port if the battery runs flat.\u003c\/p\u003e\n","brand":"Aqara","offers":[{"title":"Default Title","offer_id":42779903295584,"sku":null,"price":699.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4182\/6400\/files\/Aqara_U500_Smart_Rim_Lock.webp?v=1780229786"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0584\/4182\/6400\/collections\/InterlockMercuryX6New_3ce0b8a2-39a2-4d46-9a67-49116e888e8f.webp?v=1792763987","url":"https:\/\/interlock.com.sg\/collections\/digital-locks-for-helpers.oembed","provider":"Interlock Singapore","version":"1.0","type":"link"}
