$ 92.92
- Description The Aqara Smart Gate Lock U500 is a purpose-built smart gate lock — not a door lock pressed into gate duty. Fingerprint readers on both sides of the gate. Mechanical keys that work from both sides. No wireless mini-switch needed to leave the house. Sold and installed by PassionHome — your Authorised Aqara Dealer in Singapore — with a 24-month onsite warranty. Why the Gate Lock U500 is the ultimate gate lock Aqara Smart Gate Lock U500 — with Installation 10 Fingerprint on both sides — your family can come and go from either side of the gate. Mechanical key cylinders on both sides — emergency access from inside OR outside. Eliminates the wireless-mini-switch kludge — when a single-sided lock is mounted on a gate, you need a separate exit-trigger device on the inside. The U500 doesn’t. IP65 outer panel IP54 inner panel — engineered for Singapore monsoon weather direct-sun heat-soak. One Tap, Dual Unlock — pair with another Aqara front-door lock so a single trigger unlocks both gate door. Built-in doorbell button — pairs with the Aqara Doorbell Camera Hub G410 to see who’s at the gate. How the Gate Lock U500 compares to a repurposed door lock Door locks like the B50, U50, U100, and U400 can technically be installed on a gate — but they’re designed for solid doors with a one-sided handle. When you put them on a gate, the fingerprint reader and keypad are only on the outside. To leave the house, you need to install a separate wireless mini-switch on the inside of the gate to trigger the unlock. The Smart Gate Lock U500 is purpose-built: fingerprint readers AND mechanical key cylinders on both sides. No mini-switch needed.

Most HDB aluminium grille gates, condo perimeter gates, and landed property metal gates fall in this range. Installation requires three through-holes drilled (1×ø50mm 2×ø12mm) — the Aqara Appointed Locksmith handles this during fitting. Every gate is different; the Aqara Appointed Locksmith surveys yours before fitting to confirm compatibility. How you unlock Aqara Smart Gate Lock U500 — with Installation 12 Fingerprint — 50-print capacity, 160×160 px high-resolution sensor on both inner and outer panels. Password / PIN — regular passwords (6–10 digits), single-use temporary passwords, and scheduled timed passwords via the Aqara Home app. NFC tap-to-unlock with Apple Home Key — add your home key to Apple Wallet, then tap iPhone or Apple Watch on the NFC zone. Works even if your iPhone is out of battery. Automation — trigger unlock via Matter ecosystem automation rules. Voice control — Siri (via Apple Thread-enabled hub) or Alexa (with voice unlock password). Remote unlock — via the Aqara Home app or any compatible Matter ecosystem app, with a Thread-enabled Matter controller on your network. Bluetooth short-range — via the Aqara Home app. Mechanical key — two physical keys included, with cylinders on both sides of the gate. Works with your smart home The Gate Lock U500 is a Matter-over-Thread device. It works with Aqara Home, Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant. Apple Home Key tap-to-unlock is supported via the new Aliro standard. For remote unlock and ecosystem automations, you need a Thread-enabled Matter controller on your network — the Aqara Hub M3, Hub M100, Hub M200, Doorbell Camera Hub G410, or Camera Hub G5 Pro all work. Apple users can also use an Apple TV 4K (with the latest software), HomePod (2nd generation), or HomePod mini as the Thread Border Router. Recommended Aqara hubs for the Smart Gate Lock U500 Because the Gate Lock U500 is Matter-over-Thread (with no built-in Wi-Fi), it needs a Thread-enabled Matter controller on your network to unlock its full feature set — remote unlock from anywhere, scene automations, ecosystem voice control, and Apple Home Key tap-to-unlock. Any of these five Aqara hubs is a strong pairing — pick by use case and budget: Aqara Doorbell Camera Hub G410 — $309. The natural Gate Lock partner: combines a 2K doorbell camera Thread Border Router Matter controller in one device. Integrates directly with the Gate Lock’s built-in doorbell button so you can see who’s at the gate and unlock from Apple Home. Aqara M3 Hub — $289. Premium full-home hub: Matter controller Thread Border Router IR blaster Zigbee bridge. Best pick if you also use Aqara Zigbee accessories (sensors, switches, cameras) and want one hub running the whole home. Aqara Hub M200 — $149. Mid-tier Matter Thread Zigbee bridge with built-in IR. The balanced choice — most of the M3’s bridging power at a friendlier price. Aqara Smart Hub M100 — $89. Entry-tier Matter-ready Thread Border Router. The cheapest path to enable the Gate Lock’s remote unlock Apple Home Key features if you don’t need Zigbee bridging or IR control. Aqara Camera Hub G5 Pro — $399. Outdoor camera Thread Border Router Matter controller in one. Best if you also want outdoor video monitoring of the gate area and entry. If you already use an Apple Thread-enabled home hub (Apple TV 4K, HomePod 2nd-gen, or HomePod mini), the Gate Lock can pair through that as its Matter controller — no additional Aqara hub strictly required for Apple Home users. The Aqara hubs above add Aqara-Home-exclusive features (Night Latch Mode, gyroscope auto-lock configuration, Aqara automation engine) and broader ecosystem coverage beyond Apple-only. One Tap, Dual Unlock G410 Doorbell integration Aqara Smart Gate Lock U500 — with Installation 13 Pair the Gate Lock with another Aqara front-door lock for the One Tap, Dual Unlock scene — a single trigger unlocks both gate and front door for a smoother arrival. See the front-door pair recommendations below for the right Aqara lock by door type. The built-in doorbell button on the outer panel integrates with the Aqara Doorbell Camera Hub G410 so you can see who’s at the gate and unlock directly from the Apple Home app. Complete the entry — pair with a front-door lock The Gate Lock U500 secures the outer layer of your entry. For the inner front-door layer, pick the right Aqara lock for your door type — every Aqara lock supports the One Tap, Dual Unlock scene in the Aqara Home app so a single trigger unlocks gate front door together: HDB mortise main doors (most common in Singapore) Aqara Smart Door Lock A100 — $669.

Security, encryption, and alerts Aqara Smart Gate Lock U500 — with Installation 14 Solid metal frame with reinforced dual-hook bolts and a genuine through-lock cylinder — built to withstand prying and forced entry. AES-encrypted local storage of access credentials. Forced-entry alerts and door-left-ajar alerts pushed to the Aqara Home app. Do Not Disturb Mode — mute general alerts during set times while still notifying for forced entry or critical events. Gyroscope auto-lock — the lock detects when the gate closes and locks automatically, no contact sensor required. Two-way fingerprint design eliminates the risk of someone reaching through the gate to operate an inner-side-only lock. Battery, USB-C emergency port, and low-battery alerts The Gate Lock runs on 4 × AA batteries (LR6, included) for up to 7 months of typical use. At 5.1V the Aqara Home app sends a low-battery alert; at 4.9V the lock prompts you to top up via the USB-C emergency port on the outer panel (5V/1A — works with any standard power bank or USB-C-to-USB-C phone). Mechanical key fallback works from both sides at any battery level.

Is the lock limited to a specific door opening direction? There are no restrictions. The lock supports all door opening directions, including left/right swing and inward/outward opening.

What are the operating temperature and humidity ranges for the lock? Operating temperature: Outer panel −35°C to 66°C, Inner panel −18°C to 50°C. Operating humidity: 0 to 93% RH, non-condensing. Temperatures or humidity outside this range may affect normal operation. What materials is the lock made of?

What should I do if the lock runs out of battery? When battery voltage drops below 5.1V, the lock alerts you in advance — replace the batteries as soon as possible.

How long is the battery life of the lock? Up to 7 months on a single set of 4 AA batteries — measured in Aqara laboratories at 25°C, simulating 15 door openings and 15 automatic lock engagements per day. Battery performance decreases in low-temperature environments. Does the Smart Gate Lock U500 fit my HDB grille gate? The Gate Lock U500 is designed for outdoor metal gates with door thickness 22–28mm, backset 40–45mm, and door gap 3–7mm. Most HDB aluminium grille gates fall in this range, but every gate is different — the Aqara Appointed Locksmith surveys your specific gate before fitting to confirm compatibility. The Gate Lock also requires through-hole drilling (1×ø50mm 2×ø12mm holes), which we handle during installation. Why is the Gate Lock U500 better than putting a B50, U50, U100, or U400 on my gate? Those locks are designed for solid doors with a one-sided handle — when fitted on a gate, the fingerprint reader is only on the outside. To leave the house, you need a separate wireless mini-switch on the inside of the gate to trigger the unlock. The Smart Gate Lock U500 is purpose-built for gates: fingerprint readers AND mechanical key cylinders on both sides. No mini-switch needed. Plus gate-specific features — One Tap Dual Unlock (gate front door together), built-in doorbell button, G410 Doorbell Camera Hub integration, IP65 outer panel for monsoon weather. Is installation included in the $799 price? Yes — the $799 price includes mandatory professional installation in Singapore by the Aqara Appointed Locksmith. The Aqara Appointed Locksmith surveys your gate dimensions before installation begins and won’t proceed if the gate isn’t compatible. What’s the Singapore warranty for the Smart Gate Lock U500? 24-month onsite warranty in Singapore — warranty service comes to your door, no need to ship the lock to a service centre.
