Aqara Smart Door Lock U100 — with Installation 22 Why buy the U100 in Singapore 9 unlocking methods covering every household scenario. Fingerprint (50 enrolled, <0.5s recognition, 98.6% rate), password (75 simultaneous 8 one-time per hour, phantom password anti-peep), Apple Home Key in Wallet (iOS 15 / watchOS 8 , no hub needed), NFC card (Aqara branded Mifare M1 standard), Aqara Home app local Bluetooth remote via the bundled Hub E1, HomeKit / Siri / Google Home / Amazon Alexa voice unlock, automatic G4-doorbell integration unlock, and 2 mechanical keys for offline emergency.

Tap your iPhone or Apple Watch on the keypad to unlock. Express Mode supports Face ID / passcode unlock without opening Wallet. The Apple Home Key flow talks direct over Bluetooth NFC — no Aqara hub needed for this specifically. Versatile across three door types. Fits any wooden door with a single-bore deadbolt prep (54mm hole, 60mm or 70mm backset, 35–55mm thickness). PassionHome installs the U100 on (a) HDB metal gates with the $200 gate-accessory kit install upgrade — the gate-side use case the U100 is most often picked for, (b) interior or secondary wooden doors (study, bedroom, store-room), and (c) HDB main doors as a budget alternative to mortise smart locks (A100 / D100 / D200i). Aluminium-door installations attract an additional fee. Singapore-rated outer panel. Outer keypad is IP65 waterproof rated for daily Singapore weather. Operating temperature −35 °C to 66 °C, 0–93% RH non-condensing. The inner panel is indoor-only (not waterproof) — the U100 is designed for sheltered installation. BHMA Level 3 equivalent mechanical lock cylinder, 200,000-cycle auto-lock test passed. Bundled Aqara Hub E1 unlocks the full ecosystem. The Kit ships with an Aqara Hub E1 Zigbee hub already factory-included — no separate hub purchase. The E1 handles remote unlock from outside Bluetooth range, Matter bridging (Zigbee → Matter for Apple Home / Google Home / Amazon Alexa), Aqara Home automation triggers, and the activity log. Pair it once via the Aqara Home app at install. Authorised Aqara Dealer 24-month warranty serviced in Singapore.

Nine unlocking methods Aqara Smart Door Lock U100 — with Installation 23 Aqara documents 9 unlocking methods on the U100: Fingerprint — daily-use primary method Up to 50 enrolled fingerprints with a 98.6% recognition rate and recognition under 0.5 seconds. Enrolment via the Aqara Home app over Bluetooth at first setup, or locally on the lock. Suitable for households up to 10 members with multiple fingers enrolled per person for redundancy. Password — 75 simultaneous plus phantom-password anti-peep Stores up to 75 simultaneous passwords (ordinary temporary periodic), plus 8 one-time codes per hour. Codes are 6 to 10 digits. The phantom password feature lets you pad your real PIN with random digits before and after, up to 20 total — the lock authenticates against the correct embedded sub-sequence (anti-peep protection for entries in semi-public corridors). Apple Home Key — tap-to-unlock from iPhone or Apple Watch (no hub) After adding the U100 to Apple Home via the Matter QR code on the lock, a virtual Home Key card is generated in Apple Wallet automatically. Standard Mode: open Wallet, select the home-key card, hold the device near the NFC area on the outer panel. Express Mode (configured in Apple Home): unlock with Face ID or device passcode while holding the phone or watch near the NFC area, no Wallet interaction needed. No Aqara hub is required for Apple Home Key — this flow works direct via Bluetooth NFC. NFC card — Aqara branded and Mifare M1 compatible The U100 reads both Aqara-branded NFC cards (2 included with the Kit) AND the Mifare M1 standard format. This means existing access cards from your condo lobby, office, or gym can often double as U100 unlock credentials. Aqara Home app — Bluetooth local plus remote via the bundled hub Bluetooth 5.0 (over 20 metres in open areas) handles in-range unlock from the Aqara Home app. The factory-bundled Aqara Hub E1 in the Kit provides remote unlock from outside Bluetooth range, plus the activity log, automation triggers, and Matter bridging. HomeKit / Siri Apple Home integration via the Matter QR code on the lock. For remote unlock and Siri voice from outside the home, Apple Home needs a home hub (HomePod / HomePod mini / Apple TV) configured as the household pivot. Google Home and Amazon Alexa via the Hub E1 Google Home and Amazon Alexa connect through the Aqara Hub E1’s Zigbee → Matter bridge. Voice unlock requires a preset PIN; voice lock commands work without one. Routine and automation integration works natively once paired. Automatic unlock via Aqara G4 video doorbell When the Aqara G4 video doorbell is paired in the same Aqara Home setup, the U100 can be triggered to auto-unlock on G4 face-recognition events. Useful for hands-full arrivals when the G4 has already recognised a household member at the door. Mechanical key — emergency offline fallback Two mechanical keys ship with every U100. The mechanical key is the guaranteed offline unlock — use it if the lock is fully out of power and you don’t have a USB-C power bank handy. Aqara recommends storing the mechanical keys away from the door (in a car, office, or trusted neighbour’s home). Self-disassembly of the cylinder voids the Aqara warranty. Smart home connectivity — Matter bridged via the included hub Aqara Smart Door Lock U100 — with Installation 24 The U100 uses Zigbee 3.0 as its smart-home protocol and Bluetooth 5.0 for local app commissioning direct Apple Home Key communication. The U100 is NOT native Matter and NOT Thread — those are on Aqara’s newer U200 / U300 / U500 generation. For Matter functionality, the U100 bridges Zigbee → Matter through a Matter-supported Aqara hub. The factory Kit includes the Aqara Hub E1 which handles this bridging — no separate hub purchase needed. If you specifically need native Matter-over-Thread (no hub bridging), the Aqara U300 (single-bore lever for interior wooden doors) and U200 Lite Kit (Euro-cylinder retrofit) are the native-Matter alternatives. Security and certifications BHMA Level 3 equivalent — American Builders Hardware Manufacturers Association lock-grade equivalence (mid-tier residential security). 200,000-cycle auto-lock test passed. HomeKit Certified — Apple MFi certification, confirming Apple Home Apple Home Key support. FCC — US wireless certification. CA65 — California Proposition 65 chemical-safety compliance. IP65 (keypad / outer panel only). Daily-weather waterproof rated for sheltered outdoor installation. The indoor panel is not waterproof. 128-bit AES encryption — communication encryption between the lock and the Aqara Home cloud. Tesla-coil resistance. Aqara documents that the U100 has passed electromagnetic-compatibility testing — Tesla coils similar EM-pulse attempts cannot unlock the lock. Door fit and installation Aqara Smart Door Lock U100 — with Installation 25 What kind of door fits the U100 The U100 is an American-standard single-cylinder deadbolt replacement. It requires a wooden door (or comparable material) with a single-bore deadbolt prep: Door hole: 54 mm diameter (2 1/8″) — standard US single-bore deadbolt cutout Backset: 60 mm or 70 mm (2 3/8″ or 2 3/4″) Door thickness: 35–55 mm (1 3/8″ to 2 11/64″) Door gap: 2–10 mm Opening direction: all directions supported (left/right, inward/outward) Three Singapore use cases 1. HDB metal gates (most popular). The U100 $200 gate-accessory kit install converts the wooden-door deadbolt to a gate-door deadbolt. PassionHome’s installer assesses the gate type before fitting. This is the U100’s most common Singapore use case — smart-lock convenience to the metal gate without touching the main door. 2. Interior or secondary wooden doors. Study doors, bedroom doors, store-room doors, side-entry doors — any wooden door with deadbolt prep at the right thickness range. Bundled wooden-door install in the SGD price covers this scenario directly. 3. HDB main doors (budget tier). Singapore HDB main doors are typically mortise-prep — the U100’s deadbolt cylinder is a valid alternative if your main door has been retrofitted to accept a single-bore deadbolt prep, or you’re working with a non-standard door. Aqara’s mortise lineup (A100 / D100 / D200i) is the premium tier for HDB main doors; the U100 is a legitimate budget alternative. What’s included in the installation Standard wooden-door installation is included in the SGD price. The PassionHome installer assesses door fitment before install day, supplies the AA batteries on site, pairs the lock to your Aqara Home Matter ecosystem, and walks you through fingerprint / password / NFC setup before leaving. Aluminium-door installations and special installation requirements attract an additional fee — let PassionHome know your door type in advance via WhatsApp 65 9051 7063. Battery and emergency power Aqara Smart Door Lock U100 — with Installation 26 The U100 runs on 4 × AA (LR6) alkaline batteries. Aqara’s lab-measured battery life is approximately 8 months under typical usage (8 unlocks 8 auto-locks per day at 25 °C). The lock raises a low-battery alert in the Aqara Home app at ~20% remaining capacity. If the batteries fully deplete while you’re outside the home, the USB-C emergency power port at the base of the outer panel accepts any standard 5 V DC USB-C power bank or charger. Hold the power source against the port, and the lock momentarily powers up to accept fingerprint / password / NFC / Apple Home Key as normal. The 2 mechanical keys shipped with the Kit are the ultimate offline fallback.

Aqara documents the install flow: download the Aqara Home app, open the Smart Lock U100 page, and follow the in-app instructions. The user manual has QR codes for the installation video and the detailed electronic user manual. PassionHome includes installation on standard wooden doors with every Kit sold — the installer assesses your door before fitting and pairs the lock to your Aqara Home and Matter ecosystem before leaving. What certifications and tests has the Smart Lock U100 passed? Aqara documents: FCC, BHMA Level 3 safety-standard equivalent, HomeKit Certification, CA65, IP65 (keypad / outer panel), and a 200,000-cycle auto-locking / unlocking test. How do I bind the U100 to Google Home or Amazon Alexa? Scan the QR code in the user manual for the install video on Google or Alexa binding, then follow the on-screen guidelines. Voice unlock requires a preset PIN for security; voice lock commands work without a PIN. What materials is the Aqara Smart Door Lock U100 made from? The touch panel is matte IML for superior transparency. The outdoor (outer) panel is zinc alloy with a frosted coating for hardness. The indoor (inner) panel is plastic with a metallic coating for scratch residue resistance. What lock cylinder does the U100 use? Is it Schlage-compatible? The U100 ships with an alloy mechanical lock cylinder tested to the same safety standard as BHMA Class 3. The cylinder is a less common specification — NOT identical to Schlage. If you need to replace the cylinder, consult a locksmith first to confirm size compatibility before purchasing; self-disassembly voids the Aqara warranty. Does the U100 detect when my door is closed and locked? The U100 currently supports lock-status detection (locked / unlocked / lock-failure states). Door open / closed state detection may arrive via a future OTA update — watch Aqara firmware release notes. What kind of doors does the U100 fit? The U100 cylinder is compatible with most wooden doors with a thickness between 35 mm and 55 mm, a 54 mm bored deadbolt hole, and a 60 mm or 70 mm backset. For HDB metal gates, PassionHome offers a $200 gate-accessory kit install upgrade that converts the wooden-door deadbolt to a gate-door deadbolt. Aluminium doors and special-requirement installs attract an additional fee. Is the U100 limited to specific door-opening directions? No. The U100 supports all door-opening directions — left or right, inward or outward. Is the U100 waterproof? Can it be installed outdoors? The keypad / outer panel is IP65 rated for daily Singapore weather (rain, humidity). The indoor (inner) panel is NOT waterproof and must be installed indoors. The U100 is designed for sheltered installation — not full open-outdoor weather exposure. What is the U100’s operating temperature and humidity range? −35 °C to 66 °C, and 0–93% RH non-condensing. Operating outside this range may affect normal lock performance. (Note: the previous PassionHome page stated -20 °C to 55 °C — that was a confabulation; the Aqara-verified range above is correct.) How is the U100 powered? How long does the battery last? 4 × LR6 AA alkaline batteries. Aqara’s lab-measured average battery life is approximately 8 months under typical usage (8 daily unlock auto-lock cycles, 25 °C). Battery performance declines under low-temperature environments. Low-battery alert appears in the Aqara Home app at ~20% remaining. What happens if the U100’s batteries fully deplete while I’m outside? The outer panel has a USB-C emergency power port at its base. Hold any standard 5 V DC USB-C power bank or charger against the port — the lock momentarily powers up to accept fingerprint / password / NFC / Apple Home Key. The 2 mechanical keys shipped with the Kit are the ultimate offline fallback. How many unlock methods does the U100 support? Nine: (1) fingerprint, (2) password (ordinary, one-time, periodic), (3) HomeKit / Siri including Apple Home Key, (4) Aqara Home app (Bluetooth local remote via hub), (5) Google Home / Assistant (remote, voice PIN required), (6) Amazon Alexa (remote, voice PIN required), (7) NFC card (Aqara Mifare M1), (8) integration unlock via the Aqara G4 doorbell, and (9) mechanical key for offline emergency. When do I need to use the mechanical key? Emergency situations where the lock can’t be opened by normal methods (fingerprint / password / app / NFC / Apple Home Key). Aqara recommends storing the mechanical keys away from the door — in a car, office drawer, or trusted neighbour’s home. How many passwords can the U100 store? Up to 75 simultaneous passwords (ordinary temporary periodic), plus up to 8 one-time codes per hour. Codes are 6 to 10 digits. What is the phantom-password feature? Phantom passwords let you pad your real PIN with random digits before and after, up to a total of 20 digits — the lock authenticates against the correct embedded sub-sequence. Anti-peep protection for password entry in semi-public corridors / lift lobbies. How many fingerprints can the U100 store? Up to 50 fingerprints, with a 98.6% recognition rate and recognition in under 0.5 seconds. Multiple fingerprints per person are recommended for redundancy. What is the tailing-resistance auto-lock function? Many traditional electronic locks relock the latch 5–10 seconds after unlocking — that gap lets an intruder press the handle and tail you in. The U100 detects when the door has closed and locks immediately, closing that tailing window. What wireless protocols does the U100 use? Zigbee 3.0 and Bluetooth 5.0. The U100 is NOT native Matter and NOT Thread — Matter functionality is bridged through a Matter-supported Aqara hub. The U100 factory-includes the Aqara Hub E1 which handles this bridging. Can the U100 be unlocked remotely through the app? Yes. (1) Aqara Home app — tap the open button in the app; requires the bundled Aqara Hub E1 (or any Aqara hub) at home. (2) Apple Home — tap the open button or use Siri; requires an Apple Home Hub (HomePod / iPad / Apple TV) at home. (3) Google Home / Amazon Alexa — tap or voice command with a preset PIN; requires the Aqara hub at home. Can the U100 be unlocked by voice control? Yes — HomeKit Siri unlock requires an Apple Home Hub for remote operation. Google Assistant and Amazon Alexa support voice unlock with a preset PIN; voice lock commands work without a PIN. All voice paths require the lock to be on the home network through an Aqara hub (locally) and through the assistant’s cloud (remotely). How many user accounts does the U100 support? Up to 50 accounts — either 50 admin accounts, or 49 ordinary accounts plus 1 admin. Ordinary users can unlock; admins manage credentials and settings. How do I add Apple Home Key on the U100? iPhone running iOS 15 or Apple Watch running watchOS 8 is required. After adding the U100 to Apple Home (scan the Matter QR code on the lock), a virtual Home Key card appears in Apple Wallet automatically. If you have an Apple Watch, the card is also copied to its Wallet app. How do I use Apple Home Key to unlock? Standard Mode: open Apple Wallet, select the home-key card, hold the iPhone or Apple Watch near the NFC area on the outer panel. Express Mode (configured in Apple Home): hold the device near the NFC area; Face ID or passcode verifies and unlocks without opening Wallet. No Aqara hub is needed for the Apple Home Key flow — it works direct via Bluetooth NFC. Is there a Singapore warranty? Where is service handled? Yes. 24-month onsite manufacturer warranty in Singapore. PassionHome is the Authorised Aqara Dealer fulfilling the SG-warranty service path — no overseas RMA, no parallel-import complications. WhatsApp 65 9051 7063 for warranty cases. Is installation included in the PassionHome price? Yes — standard wooden-door installation is included. For HDB metal gates, the $200 gate-accessory kit install upgrade converts the wooden-door deadbolt to a gate-door deadbolt. Aluminium-door installations and special-requirement installs attract an additional fee — let PassionHome know your door type in advance via WhatsApp 65 9051 7063. Is there an estate group-buy for the U100? Yes — when your estate has unlocked the PassionHome group-buy, the U100 ships at the all-in estate rate with significant discount when your estate unlocks. See active estate group-buys for current rounds. How does the U100 compare to the U200 Lite Kit? Both are smart locks for wooden doors, but they’re different categories. The U100 is an American-standard single-cylinder deadbolt replacement with bundled Aqara Hub E1 Apple Home Key direct (no hub needed for that flow) Zigbee Mifare M1 NFC. The U200 Lite Kit is a Matter-over-Thread Euro-cylinder retrofit — it mounts over your existing cylinder without changing the door hardware. Pick the U100 if you need a deadbolt replacement on a wooden door or HDB gate; pick the U200 Lite Kit if you have a Euro-cylinder mortise lock and want a retrofit (no door modification).
