Description
The Aqara Smart Door Lock A100 is the value entry of Aqara’s mortise smart lock lineup for Singapore HDB and condo main doors — fingerprint + PIN + NFC + Apple Home Key + Bluetooth + Aqara Home + mechanical key (7 unlocking methods), BCA fire-rated, with a Class C mechanical cylinder embedded inside the lock body for anti-pry security. Sold by PassionHome.sg — your Authorised Aqara Dealer in Singapore — with bundled wooden-door installation, the official 24-month Aqara manufacturer warranty, and 24-month onsite warranty service in Singapore.
Why buy the A100 in Singapore
- Mortise-grade security at the entry price point ($669 with bundled installation). Most affordable BCA fire-rated mortise lock in Aqara’s Singapore lineup. Ideal for HDB upgrades on a budget, rental properties, and investment units where mortise security is required but premium features aren’t worth the extra spend.
- BCA fire-rated for HDB main-door compliance. Meets local fire-safety requirements for residential main-door applications — same certification tier as the mid-tier D100 and premium D200i.
- Seven unlock methods including Apple Home Key. Fingerprint, PIN keypad (with anti-peep padding), NFC card, Apple Home Key (iOS 15+ / watchOS 8+), Bluetooth in-app, Aqara Home remote (with Aqara hub), and mechanical-key emergency fallback.
- Class C cylinder embedded inside the lock body. Highest mechanical-cylinder security tier — even if the front panel is pried, the cylinder remains protected and requires a mechanical key to operate. Same Class C protection as the D-series mortise locks.
- Authorised Aqara Dealer + bundled wooden-door install + 24-month local warranty. PassionHome ships A100 with installation included for standard wooden HDB/condo main doors. PassionHome onsite warranty path in Singapore for warranty service. Estate group-buy pricing available — significant discount when your estate unlocks.
Mortise lock body with Class C cylinder
The A100 uses a mortise lock body with a handle-style outer panel — the traditional SG smart-lock form factor. Door thickness range covers 40 to 80 mm standard, with a longer cylinder available from the dealer for thicker doors (up to ~120 mm). All four door directions supported (left/right × outward/inward).
The Class C mechanical cylinder is embedded inside the lock body — if an attacker damages the front panel (the smart electronics), the mechanical cylinder remains protected and still requires a key to operate. Same anti-pry architecture as the mid-tier D100 and premium D200i, at the value price point.
BCA fire-rated for Singapore HDB main doors — the A100 meets local fire-safety requirements for residential main-door applications. PassionHome can confirm certification details with your installer.
Seven unlocking methods
- 1. Fingerprint — capacitive sensor on the outer handle; up to 50 enrolled fingerprints.
- 2. PIN — 6–10 digit normal PIN; up to 75 sets including scheduled PINs. Anti-peep dummy-digit padding for entering codes in public.
- 3. One-time PIN — generated remotely from Aqara Home for visitor/courier access.
- 4. NFC card — up to 25 enrolled cards.
- 5. Apple Home Key — virtual NFC card in iPhone or Apple Watch Wallet (iOS 15+ / watchOS 8+). Express Mode tap-to-unlock. Shareable via Apple Home invitations.
- 6. Bluetooth in-app — proximity unlock via Aqara Home or Apple Home app when in BLE range.
- 7. Mechanical key (emergency) — 2 emergency keys in box; recommend storing one off-site.
Aqara Home remote unlock (with an M3 or M200 hub) and Siri voice unlock through HomeKit (with an Apple Home Hub) are also available.
Smart home connectivity — HomeKit + Aqara Home via Zigbee 3.0
The A100 connects via Bluetooth 5.0 + Zigbee 3.0. HomeKit-native — pair directly in Apple Home (no Aqara hub required for HomeKit-only operation). With iOS 15+ / watchOS 8+, Apple Home Key works for tap-to-unlock; Siri voice unlock works with an Apple Home Hub. Aqara Home gives the full Aqara automation surface; an Aqara hub (M3 or M200) is required for remote unlock and automations triggered from outside the home.
No Matter Lock device profile. The A100 is a 2022-era Zigbee lock that predates Aqara’s Matter Lock rollout (Matter Lock is U-series only). For HomeKit-only households this is fine. For households with Google Home, Alexa, or SmartThings as primary, the A100 bridges via an Aqara hub through Aqara Home cloud — not Matter-native.
Battery, power, indoor operating range
8 × AA alkaline batteries; theoretical battery life ~8 months under typical usage. Low-battery alert at 20%. If batteries fully deplete, the A100 supports emergency USB-C 5V/2A external power input on the outer panel, or use the mechanical key (2 in box).
Operating temperature: 0°C to 50°C. Operating humidity: 0–95% RH non-condensing. Indoor-only IP rating (IP52 body, IP54 fingerprint module). PassionHome does NOT bundle a power adapter (the lock runs on AA batteries).

All three are BCA fire-rated and fit HDB main-door construction. The A100 is the right choice when you want mortise-grade security without the premium features — perfect for rental properties, investment units, or households where the front door upgrade is part of a wider renovation budget. For non-mortise scenarios, see U300 (interior wooden), U100 (versatile deadbolt with gate-kit option), or U200 (Euro-cylinder retrofit).
Installation in Singapore
The A100 price includes professional installation on standard wooden HDB and condo main doors. Metal and fire-rated doors may attract additional installation fee. Typical install time: 60–90 minutes. The installer fits the mortise pocket, strike plate, and Class C cylinder, then pairs the lock to your Apple Home and/or Aqara Home account before leaving.

Frequently asked questions
Is the A100 BCA fire-rated for HDB main doors?
Yes. The A100 is BCA fire-rated for Singapore HDB main-door installation — same fire-safety certification tier as the mid-tier D100 and premium D200i, at the entry price point.
What’s the difference between the A100 and the D100?
The A100 is the value entry-tier mortise lock — handle-style outer panel, semi-automatic latch operation, fingerprint as the primary biometric. The D100 is the mid tier — push-pull mortise (no handle to twist, just press to enter / pull to exit) with fully-automatic auto-lock-on-close. Both have the same BCA fire-rating, Class C cylinder, fingerprint + PIN + NFC + Apple Home Key + 7-method unlock, and 40–80 mm door fitment. The A100 is the budget choice; the D100 is the mid-tier upgrade for households who want push-pull operation and stronger anti-trailing auto-lock.
Does the A100 fit my HDB or condo main door?
Yes for almost every standard HDB and condo main door. The A100 fits wooden, metal, and steel-wood composite mortise doors with a thickness of 40 to 80 mm. All four door directions supported. PassionHome’s installation team confirms door fitment before install day.
Does the A100 work with Apple HomeKit and Apple Home Key?
Yes. The A100 is HomeKit-native — pair directly in Apple Home without an Aqara hub. With iOS 15+ / watchOS 8+, the A100 supports Apple Home Key (virtual NFC card in Wallet for tap-to-unlock). Siri voice unlock works with an Apple Home Hub (HomePod / Apple TV / iPad).
How many unlock methods does the A100 support?
Seven: fingerprint, PIN (one-time / scheduled / normal), NFC card, Apple Home Key, Bluetooth in-app, Aqara Home remote (with M3 or M200 hub), and mechanical key emergency fallback.
Does the A100 support Matter, Google Home, Alexa, or SmartThings?
The A100 is a 2022-era Zigbee lock that predates Aqara’s Matter Lock rollout (Matter Lock is on U-series only). The A100 bridges into Google Home, Alexa, and SmartThings via an Aqara hub (M3 / M200) through Aqara Home cloud — not Matter-native. For HomeKit-only households this isn’t a constraint.
How long does the battery last?
The A100 uses 8 × AA alkaline batteries; theoretical battery life is approximately 8 months under typical usage. Low-battery alert at 20%. If batteries deplete, use the emergency USB-C 5V/2A external power input or the mechanical key (2 in box).
Is installation included in the PassionHome price?
Yes — installation on standard wooden HDB and condo main doors is included. Metal or fire-rated doors may attract additional installation fee depending on door condition.
Is there a local warranty?
Yes. 24-month Aqara manufacturer warranty covered by onsite warranty service in Singapore (Singapore). PassionHome can guide you through the process — WhatsApp +65 9051 7063.
Is there an estate group-buy for the A100?
Yes — when your estate unlocks the PassionHome group-buy, the A100 ships at the all-in estate rate with significant discount when your estate unlocks. See active estate group-buys for current rounds.
