Aqara Smart Door Lock U50 — with Installation
$369.00
An American-standard single-cylinder deadbolt smart lock, designed for wooden doors and HDB gates, offering keypad password, Apple Home Key, NFC card, and remote control through an Aqara hub.
Description
The Aqara Smart Door Lock U50 is an American-standard single-cylinder deadbolt smart lock with 8 unlocking methods — keypad password, Apple Home Key, NFC card, Aqara Home app, HomeKit / Siri, Google Home and Amazon Alexa voice unlock, automatic G4-doorbell unlock, and a mechanical key fallback. Sold by PassionHome — your Authorised Aqara Dealer in Singapore — with bundled professional installation on standard wooden doors, official 24-month Aqara warranty, and 24-month onsite warranty service in Singapore. Versatile across three use cases: HDB metal gates (with a $200 gate-accessory kit + install upgrade), interior or secondary wooden doors, and HDB main doors as a budget alternative to mortise smart locks. Note: the U50 is the keypad-and-card variant of the Aqara U-series — it has NO fingerprint sensor. For fingerprint, see the U100.
Why buy the U50 in Singapore
- Entry-tier U-series smart deadbolt — keypad-and-card focus. The U50 is the budget-friendly U-series option: keypad (75 simultaneous + 8 one-time per hour, phantom-password anti-peep), Apple Home Key in Wallet (iOS 15+ / watchOS 8+, no hub needed for that flow), Mifare M1 + Aqara-branded NFC cards, Aqara Home app, voice unlock via Google / Alexa / Siri (hub required), and 2 mechanical keys for emergency offline use. No fingerprint sensor — that’s the U100’s differentiator.
- Apple Home Key works directly — no hub required. Add the U50 to Apple Home and a virtual Home Key card appears in Apple Wallet automatically (iOS 15+, watchOS 8+). 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 U50 on (a) HDB metal gates with the $200 gate-accessory kit + install upgrade — the gate-side use case the U-series deadbolts are 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. Aluminium-door installations attract an additional fee.
- Singapore-rated outer panel. Outer keypad is IP65 waterproof rated for daily Singapore weather. Outer-panel operating temperature −35 °C to 66 °C; inner panel −18 °C to 55 °C; 0–93% RH non-condensing. The inner panel is indoor-only (not waterproof) — the U50 is designed for sheltered installation. BHMA Level 3 equivalent mechanical lock cylinder, 200,000-cycle auto-lock test passed.
- Hub required separately for Matter + remote unlock. Unlike the U100 which ships with the Aqara Hub E1 factory-included, the U50 is the lock-only SKU — Matter / Google Home / Alexa / remote-unlock features need an Aqara hub purchased separately. Compatible hubs: Aqara M3 or Aqara M200.
- Authorised Aqara Dealer + 24-month warranty serviced in Singapore. PassionHome.sg is on Aqara’s official Singapore partner network; warranty service at PassionHome’s onsite warranty path in Singapore. Estate group-buy pricing available — significant discount when your estate unlocks. See active group-buys.
Eight unlocking methods
Aqara documents 8 unlocking methods on the U50:
Keypad password — daily-use primary method (75 simultaneous + phantom 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 and lift lobbies).
Apple Home Key — tap-to-unlock from iPhone or Apple Watch (no hub needed)
After adding the U50 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 U50 reads both Aqara-branded NFC cards AND the Mifare M1 standard format. Many existing access cards from your condo lobby, office, or gym can double as U50 unlock credentials — useful for household members who don’t want the Aqara Home app installed.
Aqara Home app — Bluetooth local plus remote via an Aqara hub
Bluetooth 5.0 (over 20 metres in open areas) handles in-range unlock from the Aqara Home app. For remote unlock from outside Bluetooth range, the U50 needs to be bound to an Aqara hub — PassionHome stocks the Aqara M3 and Aqara M200 hubs (sold separately).
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
Google Home and Amazon Alexa connect through an Aqara hub’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 U50 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 U50. 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 a separately-sold Aqara hub
The U50 uses Zigbee 3.0 as its smart-home protocol and Bluetooth 5.0 for local app commissioning and direct Apple Home Key communication. The U50 is NOT native Matter and NOT Thread — those are on Aqara’s U200 / U300 / U500 generation. For Matter functionality, the U50 bridges Zigbee → Matter through a Matter-supported Aqara hub. Unlike the U100 (which ships with the Aqara Hub E1), the U50 does NOT include a hub in the box — buy an Aqara M3 or Aqara M200 separately to unlock Matter, voice unlock, and remote control.
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.
- Tesla-coil resistance. Aqara documents that the U50 has passed electromagnetic-compatibility testing — Tesla coils and similar EM-pulse attempts cannot unlock the lock.
Door fit and installation
What kind of door fits the U50
The U50 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
- Opening direction: all directions supported (left/right, inward/outward)
Three Singapore use cases
1. HDB metal gates (most popular). The U50 + $200 gate-accessory kit + install converts the wooden-door deadbolt to a gate-door deadbolt. PassionHome’s installer assesses the gate type before fitting. Smart-lock convenience for the metal gate without touching the main door.
2. Interior or secondary wooden doors. Study doors, bedroom doors, store-room doors, side-entry doors. 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 U50’s deadbolt cylinder is a valid budget 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 U50 is the most budget-friendly option in the lineup.
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 keypad / Apple Home Key / 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
The U50 runs on 4 × AA (LR6) alkaline batteries. Aqara’s lab-measured battery life is approximately 6 months under typical usage (8 unlocks + 8 auto-locks per day at 25 °C). Battery performance declines under low-temperature environments. 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. The 2 mechanical keys shipped with the U50 are the ultimate offline fallback.

Quick buying guidance: pick the U50 if you want the most cost-effective U-series mortise lock with PIN + Apple Home Key tap + app + voice unlocking and you’re happy to add an Aqara hub separately for remote control. Pick the B50 at the same $369 if you’d rather have built-in Wi-Fi 6 (no hub needed for remote) and a cross-bore deadbolt form factor. Pick the U100 at $499 if you want fingerprint added. Pick the U400 at $649 if you want UWB hands-free unlocking with iPhone / Apple Watch.
How to install the Aqara Smart Door Lock U50?
Download the Aqara Home app, open the Smart Lock U50 page, and follow the in-app installation flow. The user manual has QR codes for the install video and the electronic user manual. PassionHome includes installation on standard wooden doors with every U50 sold — the installer assesses your door before fitting and pairs the lock to your Aqara Home + Matter ecosystem before leaving.
What certifications and tests has the Smart Lock U50 passed?
FCC, BHMA Level 3 safety-standard equivalent, HomeKit Certification, CA65, and IP65 (keypad / outer panel) with a 200,000-cycle auto-locking / unlocking test.
Does the U50 have a fingerprint sensor?
No — the U50 is the keypad-and-card variant in the Aqara U-series. Unlock options are keypad password, Apple Home Key, NFC card (Aqara and Mifare M1 compatible), Aqara Home app, voice (Google / Alexa / Siri via hub), G4 doorbell integration, and mechanical key. If fingerprint is important, look at the U100 instead — same form factor with 50-fingerprint capacity.
What materials is the U50 made from?
Touch panel: matte IML for superior transparency. Outer panel: zinc alloy with frosted coating for hardness. Inner panel: plastic with metallic coating for scratch + residue resistance.
What lock body and cylinder does the U50 use?
60/70 mm American-standard deadbolt body with an alloy mechanical lock cylinder tested to the same safety standard as BHMA Class 3. The cylinder is a less common specification — NOT Schlage-interchangeable; consult a locksmith if you need a future replacement.
What types of doors does the U50 fit?
Most wooden doors with a single-bore deadbolt prep, 35–55 mm thickness, 54 mm bored deadbolt hole, 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 U50 limited to specific door-opening directions?
No. The U50 supports all door-opening directions — left or right, inward or outward.
Is the U50 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 U50 is designed for sheltered installation — not full open-outdoor weather exposure.
What is the U50’s operating temperature and humidity range?
Outer panel −35 °C to 66 °C; inner panel −18 °C to 55 °C; humidity 0–93% RH non-condensing. Comfortably within Singapore’s year-round indoor and sheltered-outdoor range.
How is the U50 powered? How long does the battery last?
4 × LR6 AA alkaline batteries. Aqara’s lab-measured average battery life is approximately 6 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 U50’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 keypad / NFC / Apple Home Key. The 2 mechanical keys shipped with the U50 are the ultimate offline fallback.
How many unlock methods does the U50 support?
Eight: (1) keypad password (ordinary, one-time, periodic), (2) HomeKit / Siri including Apple Home Key, (3) Aqara Home app (Bluetooth local + remote via hub), (4) Google Home / Assistant (remote, voice PIN required), (5) Amazon Alexa (remote, voice PIN required), (6) NFC card (Aqara + Mifare M1), (7) integration unlock via the Aqara G4 doorbell, and (8) 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 (keypad / 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 does the U50 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.
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 U50 detects when the door has closed and locks immediately, closing that tailing window.
What wireless protocols does the U50 use? Is it Matter-native?
Zigbee 3.0 and Bluetooth 5.0. The U50 is NOT native Matter and NOT Thread — Matter functionality is bridged through a Matter-supported Aqara hub (M3 / M200 / G5 Pro), which you’ll need to purchase separately. If you specifically need native Matter-over-Thread, look at the U300 (single-bore lever for interior wooden doors) or U200 Lite Kit (Euro-cylinder retrofit).
Can the U50 be unlocked remotely through the app?
Yes — but remote unlock requires a hub at home. (1) Aqara Home app: requires an Aqara Hub (M3 / M200 / G5 Pro). (2) Apple Home: requires an Apple Home Hub (HomePod / iPad / Apple TV). (3) Google Home / Amazon Alexa: tap or voice with a preset PIN, requires the Aqara hub. For local Bluetooth unlock (within ~20 m), no hub is needed.
Can the U50 be unlocked by voice?
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.
How many user accounts does the U50 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 U50?
iPhone running iOS 15+ or Apple Watch running watchOS 8+ is required. After adding the U50 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.
How do I share Apple Home Key with my family?
Invite the other Apple users to join your family in the HomeKit app — once they accept, a copy of the door card is automatically generated in their Apple Wallet.
Will a Tesla coil unlock the U50?
No. The U50 has been tested against electromagnetic-compatibility (EMC) standards including Tesla-coil-style EM-pulse attempts. The lock is designed to resist these attacks; rigorous EMC testing has confirmed normal operation under high-voltage discharge conditions.
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 U50?
Yes — when your estate has unlocked the PassionHome group-buy, the U50 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 U50 compare to the U100?
Both are American-standard single-cylinder deadbolt smart locks for wooden doors and HDB gates. The U50 (S$389) is the keypad-and-card entry tier — no fingerprint sensor, no bundled hub. The U100 (S$499) is the mid tier — adds a 50-fingerprint capacity sensor and ships with the Aqara Hub E1 already factory-included. Pick the U50 if keypad + Apple Home Key + NFC is enough for your household and you already own an Aqara hub or don’t need one. Pick the U100 if you want fingerprint as a daily-use method and don’t already have an Aqara hub.
