A smart home digital lock is fast becoming the default upgrade for HDB and condo doors in Singapore, replacing fiddly keys with fingerprint, PIN, card and app entry. But the market is crowded with everything from established names to no-name imports, and the right choice depends on your door type, whether you want app control, and how much after-sales support matters to you. This guide covers the digital locks worth trusting, what separates a genuinely smart lock from a basic keypad, and how to buy without overpaying.
We focused on brands with a real Singapore presence, local installation and warranty, because a lock is the one device you can’t afford to have fail with no support. Our picks span premium ecosystem locks, dependable mid-range options and value choices, so you can match the lock to your budget and to whether you want deep smart-home integration or just reliable keyless entry. We weigh HDB fire-door compatibility, connectivity and the reality of local service.
What to look for in Singapore
- Door compatibility: confirm the lock suits your door thickness and whether it’s an HDB metal gate, fire-rated main door or condo timber door.
- Unlock methods: look for at least fingerprint plus PIN, with card and physical key backup, so no single failure locks you out.
- Connectivity: decide if you want Wi-Fi or Bluetooth app control and remote access, or a standalone lock with no app at all.
- Smart-home integration: if you use Google Home, Alexa or Apple Home, check the lock or its bridge supports your ecosystem.
- Battery type and low-battery alerts: most run on AA batteries with an emergency USB or 9V terminal, so check backup power options.
- Local installation and warranty: buy from a brand with SG installers and a real service line, since fitting quality affects reliability.
- Security features: anti-peep PIN entry, tamper alarms and auto-relock add real protection in shared HDB corridors.
- IC card and access management: family-friendly features like temporary PINs for helpers or guests are useful for condos and rentals.

The picks
Editor’s Choice
Yale (Linus / YDM series)
Yale is the safe, well-supported pick for most Singapore homes, with a wide range covering HDB gates, main doors and condo doors. Fingerprint and PIN entry are reliable, and the Yale Access app plus optional Wi-Fi bridge adds remote unlocking and guest codes. Strong local installer network makes service painless if anything goes wrong.
Pros
- Wide SG availability and support
- Reliable fingerprint reader
- App and guest-code features
Cons
- Remote features may need a bridge
- Premium models get pricey
Best for offline security
igloohome
A Singapore-born brand, igloohome is built around offline algoPIN codes that work without Wi-Fi or a cloud account, ideal if you’re wary of internet-connected locks. It’s popular with landlords and Airbnb-style rentals for time-limited PINs you can generate remotely via the app. Great security thinking, though the ecosystem features are lighter than app-first rivals.
Pros
- Works without Wi-Fi
- Time-limited PINs for guests
- Local brand and support
Cons
- Fewer smart-home integrations
- Bluetooth range is limited
Premium
Kaadas
Kaadas is the choice for a premium main door, with push-pull handles, 3D face recognition and fast fingerprint reading on its flagship models. Build quality and finish feel a cut above, suiting landed and higher-end condo doors. You pay for it, and installation on some door types needs professional fitting.
Pros
- Premium build and finish
- Fast face/fingerprint unlock
- Push-pull convenience
Cons
- Higher price band
- Needs pro installation on some doors
Best for smart-home
Aqara Smart Lock
If you already run an Aqara or Apple Home setup, Aqara’s locks slot neatly into your routines, letting the door trigger lights or arm sensors. Fingerprint and app unlocking are solid, and pairing with an Aqara hub unlocks remote access. Best value comes when it’s part of a wider Aqara ecosystem rather than a standalone lock.
Pros
- Deep smart-home integration
- Works with Apple Home
- Automations with Aqara sensors
Cons
- Best with an Aqara hub
- Fewer local installers than Yale
Best Value
Philips Smart Lock
Philips locks hit a sweet spot of trusted branding, multiple unlock methods and sensible pricing, making them a common HDB pick. You get fingerprint, PIN and card entry with app options on higher models. A dependable, no-drama choice if you want a known brand without paying flagship money.
Pros
- Trusted brand at fair price
- Multiple unlock methods
- Common in HDB homes
Cons
- App features vary by model
- Fewer ecosystem tie-ins
The verdict
For most Singapore homes, Yale is the reliable all-rounder with the best local support, while igloohome wins for offline security and Aqara for those already deep in a smart-home ecosystem.
Frequently asked questions
Are digital locks allowed on HDB doors?
Yes, you can install a digital lock on your HDB main door or gate, and no HDB permit is needed for a like-for-like lock change. Use a reputable installer who can fit it correctly to a fire-rated door and preserve the door’s integrity.
Which is the best digital lock brand in Singapore?
For most homes, Yale offers the best balance of reliability, features and local support, while igloohome leads for offline security and Kaadas for premium doors. The best brand is the one that fits your door type and has responsive after-sales in Singapore.
Do smart digital locks work if the power or Wi-Fi goes down?
Yes — digital locks run on their own AA batteries, not mains power, and most keep working offline via fingerprint or PIN even without Wi-Fi. Only remote app features need internet; local unlocking continues, and locks warn you well before batteries die.
How much does a good smart digital lock cost in Singapore?
Expect roughly $300–$600 for a solid mid-range lock with fingerprint, PIN and card entry, rising to $700–$1,500 for premium push-pull or face-recognition models. Installation is sometimes bundled, so check whether the quoted price includes fitting.
Can I unlock a smart lock with my phone?
Many models support app or Bluetooth unlocking, and with a Wi-Fi bridge you can unlock remotely or issue guest PINs from anywhere. Confirm the specific model supports app control, as some value locks are keypad-and-fingerprint only.
