Aqara Smart Door Lock B50 — with Installation 18 Why the B50 The B50 is Aqara’s entry-level smart deadbolt — built for buyers who want the convenience of a smart lock (PIN, app, voice) without paying for fingerprint sensors and NFC tap-to-unlock. Importantly, it’s the only Aqara lock with Wi-Fi 6 built in, which means you don’t need a separate Aqara hub for remote control — the lock talks directly to your home Wi-Fi. Wi-Fi 6 built in — control the lock from the Aqara Home app anywhere; no separate hub required for the basic remote-control use case (other Aqara locks like U50/U100/U200 need a Thread or Zigbee hub for remote). 5 unlock methods — PIN passcode, Aqara Home app, Alexa or Google Home voice, mechanical key, and offline / one-time / scheduled passwords for guests. 75 PIN codes and 75 user accounts — generous capacity for families, domestic helpers, contractors, short-term guests, and Airbnb-style rentals. Anti-peek PIN — enter random digits before or after your real 6–10 digit passcode (up to 20 digits total). Anyone watching can’t tell which digits are real. USB-C emergency power port — plug any USB-C power bank into the front of the lock if the AA batteries run flat. No lockouts. AES-128 encryption end-to-end 100,000-cycle auto-lock durability tested. Certifications: FCC, IC, CE RED, RCM. Aqara Smart Door Lock B50 — with Installation 19 Singapore main-door fitment The B50 is a smart deadbolt designed for cross-bore door prep — the standard format used on most Singapore wooden doors with thickness between 35 mm and 55 mm. PassionHome’s Singapore installation team handles the retrofit, including any adjustment needed where a door uses a different existing lock format. It’s the most cost-effective Aqara smart-lock option for HDB main doors where you want keyless entry, app control, and voice unlocking without paying for the premium U-series features (fingerprint, NFC tap-to-unlock, Apple Home Key). The included installation hardware covers most situations — mounting plate screw kit (M3 × 8 mm), bolt and strike plate screw kit (M4 × 25 mm), and opposite-pull screw kit (M6 × 55 mm) for thick doors. Doors with non-standard preparation (e.g. existing mortise where you want to switch to deadbolt format) may need additional adjustment — our SG installation team will assess on site and let you know before any work begins. Not sure if your door is compatible? WhatsApp 65 9051 7063 with a photo of your existing lock and we’ll confirm fitment before you order. Aqara Smart Door Lock B50 — with Installation 20 How you unlock Five everyday unlock methods, plus a mechanical key for emergencies: PIN passcode — 6 to 10 digits, with anti-peek buffer letting you pad your real code with random digits. The lock supports up to 75 distinct PINs at once — assign a unique one to each family member, helper, contractor, or guest. Aqara Home app — Bluetooth nearby or remote via Wi-Fi. Lock/unlock from your phone whether you’re at the door or thousands of kilometres away. Voice — “Alexa, lock the front door” or “Hey Google, lock the front door.” (Voice unlock requires a preset PIN as confirmation per Aqara’s security policy.) Mechanical key — 2 emergency keys included. Keep one outside the home (riser, neighbour) for the rare case where everything else is unavailable. One-time / scheduled passwords — issue a time-limited code to a cleaner, contractor, or short-term guest. Set a one-time code (single use), a recurring window (e.g. every Monday 10am–2pm), or a one-off valid for 20 minutes. Up to 8 one-time codes can be generated per hour. Aqara Smart Door Lock B50 — with Installation 21 Works with your smart home The B50 connects to all major ecosystems — directly for Wi-Fi-native ones, and via an Aqara Matter-capable hub for Apple Home and the broader Matter ecosystem. Aqara Home — native control, no hub required. Amazon Alexa — direct connection via the B50’s built-in Wi-Fi 6, no hub required. Google Home / Google Assistant — direct connection via Wi-Fi 6, no hub required. Apple Home (via Matter) — bind the B50 to an Aqara Matter-capable hub (M3, M100, G5 Pro, or G410), then bridge to Apple Home using the Matter setup code. Note: the B50 is not HomeKit-native and does not support Apple Home Key tap-to-unlock — those features sit on Aqara’s U-series locks (U50 / U100 / U200 / U300). Matter (other ecosystems) — same path: bind to an Aqara Matter hub, then bridge to SmartThings, Home Assistant, or any other Matter controller. Aqara automations — once paired, the B50 can trigger and respond to other Aqara devices in your home. Example: unlock the door at 6 pm → lights turn on, AC switches on, video doorbell history loads on your phone.

The trade-off vs. the higher-tier U-series locks: no fingerprint sensor and no Apple Home Key tap-to-unlock.

Pick the U50 at the same $369 if you prefer the U-series mortise form factor with Apple Home Key tap (note: hub needed for remote). Pick the U100 at $499 if you want fingerprint added on top. Pick the U400 at $649 if you want UWB hands-free unlocking with your iPhone or Apple Watch. Built-in security features The B50 isn’t just convenient — it includes the security features Aqara built into its higher-tier U-series locks, scaled down for the entry-level price point. Anti-peek PIN entry — pad your 6–10 digit code with random digits before or after (up to 20 digits total input). Shoulder-surfers can’t tell what your real code is. Failed-attempt lockout — repeated wrong PIN entries lock the keypad for a configurable cooldown period. App and mechanical key still work during lockout. Timed auto-lock — the deadbolt locks itself after a configurable delay so you never leave the door unlocked by accident. Night latch mode — bedtime mode that disables all PIN unlocks until you re-enable from inside. Only the mechanical key works from outside. Do Not Disturb mode — silences the keypad beeps and lock voice prompts on a schedule (e.g. 10pm–7am) so the lock doesn’t wake the family. AES-128 end-to-end encryption for all Wi-Fi and Bluetooth communications. USB-C emergency port — even if the batteries run flat, plug in any USB-C power bank to power up and unlock. No need to break in or call a locksmith. Door-status monitoring — the Aqara Home app shows real-time lock state (locked / unlocked / lock failure) and sends push alerts on suspicious activity.

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. Questions buyers ask What type of Wi-Fi does the B50 support? The B50 supports 2.4GHz Wi-Fi only, not 5GHz. If your router defaults to 5GHz, you’ll need to manually switch to 2.4GHz for the initial pairing. Most Singapore home routers run dual-band by default and the 2.4GHz band stays available. Can all features of the B50 be controlled via Wi-Fi? Most features yes — locking, unlocking, setting user passwords, one-time and recurring passwords, and most configuration options run over Wi-Fi. A few features still require Bluetooth: initial door-lock detection, lock mode switching, changing Wi-Fi networks, and night latch mode. How do I control the B50 in Apple Home? You’ll need an Aqara Matter-capable hub (M3, M100, G5 Pro, or G410). Bind the B50 to the hub in the Aqara Home app, then add the hub to Apple Home using the Matter setup code. The B50 itself is not HomeKit-native — Matter via hub bridge is the supported path. What certifications has the B50 passed? FCC, IC, CE RED, and RCM certifications, plus 100,000 cycles of automated locking and unlocking durability testing. What kind of lock body does the B50 use? The B50 is equipped with a 60/70 mm deadbolt — the standard US single-cylinder cross-bore format. What types of doors are compatible with the B50? The B50’s cylinder fits most wooden doors with a thickness of 35 mm to 55 mm. PassionHome’s Singapore installation team handles the retrofit on HDB and condo main doors — WhatsApp 65 9051 7063 with a photo of your existing lock if you want fitment confirmed before you order. Is the B50 limited to specific door-opening directions? No. The B50 supports all door-opening directions, including left or right, and inward or outward swing. Is the B50 waterproof and can it be used outdoors? The B50’s front panel is IPX3-rated, which means it tolerates splashing water but is not recommended for fully exposed outdoor use. For most Singapore main doors with a sheltered porch or HDB landing, this is fine. For fully exposed gates or doors hit by driving rain, consider a higher-IP-rated U-series lock instead. How long is the battery life of the B50? Up to 6 months on a fresh set of 4 × AA batteries, measured at 25°C with 5 PIN entries and 5 Wi-Fi remote unlocks per day. Heavy use, cold temperatures, or weak Wi-Fi will shorten this. The Aqara Home app alerts you when the battery drops below 20%. What should I do if the B50 runs out of power? If you’re outside, plug any USB-C power bank into the emergency port at the bottom of the outer panel — that gives the lock enough juice to authenticate your PIN or app unlock. If you’re inside, just open the battery cover on the inner panel and swap in fresh AAs. How many ways can I unlock the B50? Five: PIN passcode (ordinary, one-time, or recurring), Aqara Home app (Bluetooth or remote), Google Home or Amazon Alexa voice control, mechanical key, and Matter unlock (after binding to an Aqara M3 / M100 / G5 Pro / G410 hub). How many passwords does the B50 support? Up to 75 passwords simultaneously, including ordinary and scheduled types. You can also generate up to 8 one-time passwords per hour for guests or contractors. What’s the password length and is anti-peek supported? Passwords are 6 to 10 digits. Anti-peek lets you enter random digits before or after your real password — up to 20 digits total — so anyone watching can’t tell which digits are real. The lock recognises the correct 6–10 digit sequence inside the longer input string. Does the B50 fit a Singapore HDB main door? Yes — the B50 is one of the most cost-effective Aqara smart-lock options for HDB main doors. PassionHome’s Singapore installation team handles the retrofit, including any adjustment needed where your existing lock format differs from the B50’s standard cross-bore prep. WhatsApp 65 9051 7063 with a photo of your current lock and we’ll confirm before you order. Is installation included in the $369 price? Yes. The $369 listed price includes Singapore installation by PassionHome’s smart-lock installation team. WhatsApp 65 9051 7063 after ordering to book your installation slot — typically within 3–5 working days of order confirmation. What’s the Singapore warranty for the B50? 24-month onsite manufacturer warranty in Singapore — warranty service comes to your door, no service-center trip needed.
