The Aqara Smart Door Lock A100 is one of the more popular digital locks in Singapore for HDB owners who want fingerprint, PIN and app entry from a brand already trusted for sensors, hubs and cameras. This guide centres on the A100 and its close variants, then places them against the rest of Aqara’s lock range so you can pick the model that actually fits your door, gate and smart-home setup. If you already run Aqara devices, adding an A100 keeps everything in a single app with shared automations, which is a big part of its appeal locally.
We wrote this for buyers weighing the A100 against Yale, Kaadas, igloohome and Lockin, especially households invested in Apple Home, Google Home or Alexa. The A100 line has earned its following in Singapore because it pairs reliable fingerprint entry with fair pricing and, on some versions, Matter and Zigbee connectivity for deeper automation. A digital lock is only as good as its fitting, so we also weigh how each model suits common HDB fire-rated doors and metal gates, and stress confirming compatibility with a dealer before you commit. We judged every pick on unlock methods, door fit, smart-home integration, battery life, app features and SGD value including installation. Lock prices move with promotions, so treat each figure as an indicative range and confirm the latest quote before buying.
What to look for in Singapore
- HDB door and gate compatibility — confirm your chosen A100 variant fits your door thickness and mortise before buying.
- Unlock methods that suit your household — fingerprint, PIN, app, card and a physical key backup.
- Which A100 version you need — the Zigbee model needs an Aqara hub, while the standalone version works without one.
- Smart-home integration — Matter, Apple Home, Google Home and Alexa support so the lock joins your ecosystem.
- Battery life and clear low-battery alerts, plus an emergency USB-C power option for lockouts.
- Humidity and weather resistance for locks near open HDB corridors and lift lobbies.
- Temporary and scheduled PINs for helpers, family and short-term guests.
- Local warranty and support, as Aqara is widely sold and serviced across Singapore.

The picks
Editor’s Choice
Aqara Smart Door Lock A100 Zigbee
The A100 Zigbee is the sweet spot for households already running an Aqara hub, tying fingerprint and app entry into the same automations as your sensors and cameras. Fingerprint recognition is fast and reliable, and Zigbee keeps the lock responsive for remote checks and door-open alerts. It is the model most Aqara users should default to, and pairing it with existing Aqara sensors lets you trigger lights or notifications the moment the door opens.
Pros
- Deep Aqara ecosystem automation
- Fast, reliable fingerprint
- Strong SG availability
Cons
- Needs an Aqara hub for remote features
- Fit must be checked per door
Best for Apple Home
Aqara Smart Door Lock A100 Pro
The A100 Pro adds NFC and tighter Apple Home integration, so you can tap to enter with an iPhone or Apple Watch and use Home Key. It is the pick for iOS-heavy households that want a premium unlock experience. Everything is managed cleanly through the Aqara and Home apps.
Pros
- Apple Home Key and NFC entry
- Polished fingerprint and app control
- Good for iOS households
Cons
- Premium over standard A100
- Some features favour Apple users
Best for retrofit
Aqara Smart Lock U200
If your door already has a deadbolt — common in condos — the U200 retrofits over the inside without replacing the whole lock, while adding Matter over Thread and Apple Home Key. It is the flexible choice when a full lock swap is impractical. A neat way to modernise an existing door.
Pros
- Retrofit, keeps existing hardware
- Matter and Apple Home Key
- Less invasive install
Cons
- Deadbolt-style doors only
- Not for all HDB setups
Best Value
Aqara Smart Lock U50
The U50 covers the essentials — fingerprint, PIN and app entry — at Aqara’s most accessible price, making it a sensible pick for budget-minded HDB owners. You lose some premium extras but keep the reliable core experience. Good value for a first digital lock.
Pros
- Most affordable Aqara lock
- Reliable fingerprint and PIN
- Simple daily use
Cons
- Fewer premium features
- Basic integration versus Pro
The verdict
For most Singapore homes the Aqara A100 Zigbee is the pick if you run an Aqara hub, while the A100 Pro suits Apple Home households and the U50 covers tighter budgets.
Frequently asked questions
Does the Aqara A100 need a hub to work?
It depends on the version. The A100 Zigbee needs an Aqara hub for remote access and automations, while the standalone A100 works on its own for local fingerprint and PIN entry. Check which variant you are buying before you order.
Will the Aqara A100 fit an HDB fire-rated door?
Often yes, but you must confirm door thickness and mortise dimensions with the dealer before buying. HDB doors vary, and some gates and doors need adapters. A proper on-site check avoids costly returns and re-drilling.
Is the Aqara A100 good value versus Yale and Kaadas in Singapore?
The A100 usually undercuts comparable Yale and Kaadas models while offering strong fingerprint reliability and smart-home integration. If you already use Aqara devices, the ecosystem tie-in adds further value. Compare total cost including installation.
How long does the Aqara A100 battery last?
Most owners get several months on a charge with normal use, and the lock warns you well before it runs flat. If it does die, a USB-C emergency power option lets you unlock and recharge. Keep a physical key as backup.
Can I give my helper or guests temporary access?
Yes. You can create temporary or scheduled PINs and fingerprints in the Aqara app, then revoke them anytime. This is useful for helpers, relatives and short stays, and you get entry notifications for peace of mind.
