Aqara U100 Smart Lock: The Ultimate Guide to Door & Gate Security in Singapore
The Only Smart Lock You Need for Both Doors and Gates
Finding a smart lock that works for both your main door and your HDB gate has always been a challenge—until now. The Aqara U100 Smart Lock is specifically engineered to handle the unique demands of Singapore's diverse residential security needs. Whether you're installing it on a wooden door, metal gate, bedroom door, or outdoor entrance, the U100 delivers premium security, weatherproof durability, and seamless smart home integration.
With IP65 waterproofing, Apple Home Key support, and 98.6% fingerprint accuracy, the U100 represents the next generation of versatile smart lock technology for Singapore homeowners.
Why the Aqara U100 Stands Out: Doors AND Gates
Most smart locks force you to choose: door lock or gate lock. The Aqara U100 eliminates that compromise. Here's why it's the perfect solution for both applications:
For Wooden Doors (Main Entrance, Bedroom, Study):
- Sleek, modern design that complements contemporary interiors
- Deadbolt locking mechanism for robust security
- Auto-lock function ensures you never leave your door unsecured
- Silent operation perfect for bedrooms and quiet spaces
- Apple Home Key for effortless entry without fumbling for keys
For Metal Gates (HDB Gates, Landed Property Gates, Secondary Entrances):
- IP65 waterproof rating protects against rain, humidity, and outdoor elements
- Corrosion-resistant construction built for Singapore's tropical climate
- Visible deterrent to potential intruders with premium appearance
- Remote unlock capability via Aqara Hub—let visitors in from anywhere
- Durable keypad designed to withstand frequent outdoor use
⚠️ Critical Installation Note for Gates: The U100 requires a metal gate with a thicker shaft or additional gate modification for proper installation. Standard HDB gates may need reinforcement or replacement to accommodate the lock's deadbolt mechanism. We strongly recommend professional assessment before purchasing for gate applications to ensure compatibility and avoid installation issues.
Apple Home Key: Your iPhone Is Your Key
The Aqara U100 brings Apple Home Key technology to both your door and gate—a revolutionary feature that transforms your iPhone and Apple Watch into secure, convenient access devices.
How It Works: Simply hold your iPhone or Apple Watch near the lock, and it unlocks instantly via NFC (Near Field Communication). No need to:
- Wake your phone
- Open an app
- Enter a passcode
- Have an internet connection
Real-World Scenarios:
Scenario 1 - Arriving Home with Groceries: You pull up to your gate with both hands full of shopping bags. Instead of setting everything down to search for keys, you simply tap your Apple Watch against the gate lock, drive in, then tap your iPhone against your main door lock. Seamless, keyless entry from gate to living room.
Scenario 2 - Morning Jog: You head out for a run with just your Apple Watch. No keys, no phone, no wallet. When you return, your watch unlocks both your gate and door. The U100 works even when your device battery is critically low, ensuring you're never locked out.
Scenario 3 - Elderly Parents: Your parents struggle with remembering PIN codes and handling small keys. With Apple Home Key, they simply tap their iPhone—a device they already carry—against the lock. Simple, dignified, and secure.
6 Unlocking Methods: Flexibility for Every Situation
The Aqara U100 offers six distinct access methods, making it one of the most versatile smart locks available:
1. Fingerprint Recognition (98.6% Accuracy)

IP65 Waterproof: Built for Singapore's Weather
Singapore's tropical climate is brutal on outdoor electronics. The Aqara U100's IP65 waterproof rating means it's engineered to handle:
- Heavy rain and monsoons – Complete protection against water jets from any direction
- High humidity – Internal components sealed against moisture damage
- Direct sun exposure – UV-resistant materials prevent fading and degradation
- Dust and debris – Fully sealed against particulate ingress
What IP65 Means:
- IP6X (Dust): Completely dust-tight. No ingress of dust even during prolonged exposure.
- IPX5 (Water): Protected against water jets. Can withstand rain, splashing, and hosing.
This makes the U100 ideal for:
- HDB corridor gates exposed to rain
- Landed property gates facing the elements
- Outdoor secondary entrances
- Covered but humid environments
Comparison: Most indoor smart locks are rated IP20-IP40, making them unsuitable for outdoor use. The U100's IP65 rating puts it in a different league entirely.

The Aqara U100 isn't just a lock—it's a smart home trigger that can orchestrate your entire living environment.

Auto-Lock with Door Sensing: Never Forget to Lock Again
One of the U100's most valuable features is its built-in gyroscope that detects door/gate position and status.
How It Works:
- Gyroscope sensor detects when door/gate closes
- Configurable delay (e.g., 5 seconds, 30 seconds, 1 minute)
- Lock automatically engages after delay
- Notification sent to your phone confirming lock status
Why This Matters:
- Forgetful moments: Rushing out for work, you forget to lock the gate. The U100 locks it automatically.
- Children: Kids come home from school and forget to lock the door. Auto-lock ensures security.

Installation Options: Door Lock vs. Gate Lock
The Aqara U100 is available in three configurations to suit your specific needs:
Option 1: Door Lock
- Standard configuration for wooden doors
- Includes all accessories for door installation
- Suitable for main doors, bedroom doors, study doors
- Professional installation recommended

- Professional assessment required before purchase
Option 3: Gate Lock with Gate Modification

⚠️ Critical Disclaimer for Gate Installation:
The Aqara U100 requires a metal gate with a thicker shaft to accommodate the deadbolt mechanism. Most standard HDB gates have shafts that are too thin for proper installation.
You will need either:
- A new metal gate with reinforced shaft (thicker tubing)
- Professional modification of your existing gate to reinforce the shaft
- Welding of additional support structures
Do NOT purchase the "Gate Lock Alone" option unless:
- You have confirmed your gate has a compatible thick shaft
- You have consulted with our installation team
- You have a separate gate supplier who can provide compatible gates
We strongly recommend:
- Free pre-installation assessment by our team
- "Gate Lock with Gate Modification" package for guaranteed compatibility
- Professional installation to ensure warranty coverage
Why This Matters: Improper installation on incompatible gates can result in:
- Lock malfunction or failure
- Gate structural damage
- Voided warranty
- Safety hazards
- Wasted time and money
