Aqara U500 Gate Lock
$599.00 – $799.00Price range: $599.00 through $799.00
Purpose-built smart gate lock for iron gates and grille doors — fingerprint and key access on both sides, PIN with anti-peep, NFC, Apple Home Keys and Matter over Thread.
Description
A purpose-built smart lock for HDB gates

The Aqara U500 Gate Lock is the first purpose-built Aqara gate lock, designed for iron gates and grille doors. Its defining feature answers the classic gate problem directly: fingerprint and key access on both sides, so unlocking from the inside needs a registered fingerprint or key — there is no exposed knob or thumb turn for anyone to reach through.
- Fits gates 22–28 mm thick; backset 40–45 mm; door gap 3–7 mm
- Gate and frame must sit flush — grille, mortise and clearance designs vary, so not every gate fits
- Fingerprint and key on both sides; PIN with anti-peep, NFC and Apple Home Keys outside
- IP65-rated outer panel with a built-in doorbell button
- 4 AA batteries, up to 7 months, USB-C emergency power
The U500 works standalone with no hub at all, and Matter over Thread connects it to Apple Home, Google Home, Amazon Alexa or SmartThings. A compatible Aqara hub adds Aqara Home automations and lock-to-lock pairing. New to digital locks?

Frequently asked questions
Will the U500 fit my HDB gate?
It fits gates 22–28 mm thick with a 40–45 mm backset and a 3–7 mm door gap, and the gate and frame must sit flush. Grille spacing, mortise cut-outs and clearance vary between gates, so not every gate qualifies — send us a photo and we’ll confirm before you order.
Does it need an Aqara hub?
Not for everyday use — the lock works standalone. Matter over Thread mode needs a Matter Controller and Thread Border Router from your chosen ecosystem. A compatible Aqara hub is needed for Aqara Home integrations, and an Aqara Matter hub if you want it to sync with another Aqara door lock.
Does it support Apple Home Keys?
Yes. Add the key to Apple Wallet and tap to unlock with an iPhone (XR/XS or later) or Apple Watch (Series 4 or later), in Express Mode or a stricter mode that asks for Face ID or a passcode first. Tap to unlock keeps working even when your iPhone is out of battery.
Why does fingerprint on both sides matter on a gate?
A gate’s open design lets anyone reach through to the inside of the lock. On an ordinary lock, that means the interior thumb turn or knob can be turned by a stranger. The U500’s inside panel needs a registered fingerprint or a key, so reach-through unlocking simply doesn’t work.
Can it unlock together with my front-door lock?
Yes — One Tap, Dual Unlock pairs the U500 with another Aqara smart lock through an Aqara Matter hub, opening gate and front door together. We install exactly this combination in our Door + Gate package.
Is installation included?

Aqara Smart Gate Lock U500
Dual-side security, inside and out.
Purpose-built for iron gates and grille doors — fingerprint and key on both sides, Apple Home Keys, and Matter over Thread.
- Fingerprint on both sides
- Apple Home Keys
- Matter over Thread
- IP65 outdoor-rated
Dual-side security
Two-way access control: fingerprint & key
The fingerprint and key lock exists on both sides of the gate, ensuring convenient access for you while eliminating the risk of somebody reaching through the gate.

From outside
Fingerprint, PIN with anti-peep protection, NFC card or Apple Home Key — pick whatever is in your hand.

From inside
A registered fingerprint or a key. No exposed knob or thumb turn means reach-through unlocking simply does not work.

For guests
Offline one-time and scheduled PIN codes let helpers and visitors in without sharing your own credentials.
Apple Home
Convenient unlocking with Apple Home Keys
Simply add your home key to Apple Wallet and unlock the gate with a single tap of your iPhone or Apple Watch — it even works when the phone is out of battery or offline.

Tap to unlock
Express Mode unlocks with a quick tap, or choose the stricter mode that asks for Face ID or a passcode before the gate opens.

Remote Home Key sharing
Share access remotely via the Apple Home app and grant entry through Apple ID — no extra apps or accounts required.
Works with everything
Matter over Thread
Powered by Matter over Thread and the new Aliro standard, the U500 ensures secure and seamless access across Apple Home, Home Assistant, Amazon Alexa, Google Home and Samsung SmartThings.

Biometrics
Ultra-responsive biometric accuracy
A high-resolution 160×160 pixel sensor identifies your fingerprint instantly and accurately, and stores up to 50 unique prints — kept on the lock itself, protected with AES encryption.
Built for outdoors
Sturdy hardware for long-term reliability
A gate lock lives outside. The U500 is engineered for exactly that.

IP65 weatherproof (outer panel)
Engineered to withstand dust, splashes and heavy rain, delivering reliable performance in demanding outdoor conditions.

Solid metal with dual-hook latches
A full metal frame, reinforced dual-hook bolts and a genuine through-lock cylinder, built to withstand prying and forced entry.

Dedicated doorbell button
A built-in bell button means no separate wireless doorbell to buy or mount.
Power
Reliable power, zero battery anxiety
Four easily replaceable AA batteries run the lock for up to 7 months — and it warns you long before they run out.



Aqara Home
Excellent Aqara Home features
With a compatible Aqara hub, the U500 picks up the conveniences that make a lock feel effortless.

Gyroscope auto-lock
A built-in gyro sensor detects when the gate is closed and locks automatically — no extra contact sensor needed.

Do Not Disturb mode
Mute general alerts during set hours while still being notified of forced entry, a gate left ajar or other critical events.

One tap, dual unlock
Pair the gate lock with another Aqara smart lock via an Aqara Matter hub and open the gate and front door together.
Automations
Create automations to make your home smarter
The U500 responds to time, presence and other Aqara devices — and tells the rest of your home when you arrive.

See who is there
Enhanced security with Aqara Doorbell G410
The U500 integrates with the Aqara Doorbell Camera Hub G410, so you can see who is at the gate and unlock directly from the Apple Home app.

Arrive home
Open the gate, activate your home
Set up when-if-then rules — for example, turn the entrance lights on automatically the moment the gate unlocks.
Installation
Integrated lock design, easy installation
The all-in-one mechanism eliminates the need for a separate mortise lock, and installation needs only a PH1 screwdriver — or choose “Lock + installation” above and our team handles everything.

The U500 series
One lock, three configurations
The same dual-hook security and unlocking options, engineered for two more door types.

U500 Rim Lock
Surface-mounted for solid doors 20–60 mm thick — add smart access without replacing the existing lockset.

U500 Glass Door Lock
Clamp-on and drill-free for frameless glass doors with 8–12 mm glass — no drilling, no damage.
