A smart lock system is more than a single lock: it is the lock, its app, and the wider ecosystem that ties access to your phone, family members, cameras and automations. For Singapore homes that want coordinated control, such as one fingerprint working on both the gate and main door, remote PIN sharing, and access logs, choosing the right system matters as much as the hardware. This guide compares the strongest lock ecosystems available and installed locally.
This is for homeowners building a connected home who want their lock to work smoothly with the rest of their smart-home setup rather than as an island. We focused on brands offering a genuine system, with reliable apps, gate-and-door pairing, and local support, weighing security, integration with Google Home or Apple HomeKit, and value in SGD including installation. Our picks are independent, and the SGD prices are indicative ranges that change often, so treat them as a guide and confirm the latest price and any hub or bridge cost before buying. We have favoured systems with genuine local support, since an access setup you rely on daily needs service you can actually reach.

- Integration with Google Home, Apple HomeKit or your existing smart-home platform for automations.

The picks
Editor’s Choice
Yale (Yale Access / Home) System

Pros
- Matching gate and door locks
- Best local support and warranty
- Reliable app and access logs

- Full system adds up in cost
- Some features need a connect bridge
Best for Smart-Home Integration

Aqara turns your lock into part of a wider smart home, linking it with sensors, cameras and HomeKit or Google Home automations through its hub. Ideal if you want the door to trigger lights or notify you as part of a connected routine.
Pros
- Deep smart-home automations
- HomeKit and Google Home support
- Expandable ecosystem
Cons
- Needs an Aqara hub
- Best value within the Aqara world
Best for Remote Management

- Fast, accurate fingerprint

Best for Samsung Households
Samsung SmartThings Lock
If your home already runs on Samsung SmartThings, Samsung’s connected locks slot straight into that app alongside your other devices, with a robust build and reliable card and PIN access. A natural fit for SmartThings households wanting one app for the whole home, though the ecosystem is less open than Aqara’s.
Pros

Match the ecosystem to how your household shares access, and buy through authorised dealers for full-system warranty.
Frequently asked questions
What makes a smart lock a ‘system’ rather than just a lock?
A system ties the lock to an app, user management and often the wider smart home, so you can pair gate and door locks, share time-limited codes, view access logs and trigger automations. It is about coordinated control across your home rather than a standalone lock on one door.
Can one fingerprint work on both my HDB gate and main door?
Yes, if you choose matching gate and main-door locks from the same brand such as Yale or igloohome, you can enrol one fingerprint set for both. This is one of the biggest conveniences of buying a coordinated system rather than mismatched locks.
Do smart lock systems work with Google Home or Apple HomeKit?
Many do; Aqara supports HomeKit and Google Home, while Yale and Samsung integrate with their own and third-party platforms. Confirm the specific model and hub requirements, as integration often needs a bridge or hub to enable remote and voice control.
How much does a full smart lock system cost in Singapore?
A single connected lock runs roughly $300 to $1,000 in SGD installed, and pairing gate and main-door locks or adding a hub raises the total accordingly. Budget for installation and any bridge, and buy through authorised dealers for warranty across the system.
Do I need a hub for a smart lock system?
It depends on the brand: Aqara systems use a hub to enable remote control and automations, while some Yale and igloohome models work over Bluetooth or offline codes without one. A hub unlocks remote unlocking, notifications and integration with lights and sensors. Decide how much remote and automation control you actually want, then choose a system whose hub requirements match your needs rather than paying for capability you will not use.
