For HDB households, synchronised digital locks offer added convenience: synchronised unlocking lets you unlock both your gate and main door with a single action, saving you the hassle of operating two locks separately.
With so many smart locks in Singapore, which should you choose? In this guide, we’ll look at some solid options (pun intended) to help you find a digital lock that fits your needs and budget.

What Is a Digital Lock?
A digital lock (or electronic lock) is a keyless locking system that uses electronic authentication to control the lock.
Instead of using a traditional metal key, homeowners unlock their doors using digital authentication methods such as fingerprint scans, PIN codes, RFID cards, facial recognition, or smartphone access.
Most modern digital locks also offer features such as automatic locking, temporary access codes, and built-in cameras.
In summary, a digital lock provides these benefits:
- Convenient keyless entry
- Locks are harder to pick as the key cylinder is hidden
- Automatic locking, no need to worry whether you’ve locked the door when you leave
- Multi-point locking system to make it more difficult to break into
- Smart monitoring on selected models
For HDB homes, most digital locks also support door-to-gate synchronisation, letting you unlock your gate and door at the same time.
How Does HDB Door-and-Gate Synchronisation Work?
With traditional locks, HDB owners must unlock their metal gate and main door separately to enter.
However, compatible digital lock bundles simplify this process with synchronised unlocking, letting you unlock both locks with one authentication action.
For example, scanning your fingerprint or face at the digital gate can automatically unlock the main door, so you don’t have to scan twice or enter separate PIN codes.
This is especially convenient when you return home with groceries or your hands full. However, not all digital lock bundles support synchronisation, so check that both locks are compatible before purchasing.
Are Digital Locks Safe?
Digital locks are generally safe and can provide reliable home security. For one, most digital locks hide their mechanical keyhole and use it only as an emergency backup, reducing exposure to traditional lock-picking.
Modern digital locks may also include advanced security features such as fingerprint and facial recognition, real-time alerts, remote monitoring, and two-factor authentication, depending on the model.
While digital locks can technically be hacked, such attacks are uncommon and often require considerable technical expertise.
Experts also say intruders may use voltage disruptors to interfere with vulnerable digital locks, but this is more likely with lower-grade models.
A more common security risk comes from everyday habits, such as using predictable PIN codes, sharing RFID access cards, or failing to manage access permissions properly. Choosing a reputable digital lock and practising good security habits can help minimise these risks.
Are Digital Locks Safe for HDB Fire-Rated Doors?
Yes, as long as the lock meets the applicable fire-safety requirements.
Since 1 March 2024, SCDF has required digital locks installed on fire-rated doors to have suitable fire-resistance certification.
Homeowners should check the lock’s Certificate of Conformity (CoC), confirm that its fire rating matches their door, and ensure a mechanical fail-safe mechanism allows emergency exit even when electrical power is unavailable.

Paired with the Aqara M100 hub, the locks can also integrate with Apple Home and support connected-home automations.
Unlike some conventional synchronised systems, Apple Home Key may require separate taps at the gate and main door. However, its Apple ecosystem compatibility makes it especially appealing to homeowners who prefer using their devices rather than carrying keys or access cards.
What to Look Out for in a Digital Lock
Beyond price and features, choose a digital lock that is compatible with your HDB entrance and supported by a dependable local service provider.
Door and Gate Compatibility
Check your door thickness, gate design and clearance between both entrances. Confirm whether the selected bundle supports synchronised unlocking and whether installation modifications cost extra.
Safety
Besides reliable locking mechanisms and emergency access, consider the digital lock’s cybersecurity features. Look for reputable manufacturers that use encrypted communication, offer two-factor authentication and provide regular security updates.
For HDB fire-rated doors, also ensure the selected lock has the appropriate fire-resistance certification.
Smart Features
Consider which access methods your household actually needs. Fingerprints and PIN codes offer everyday convenience, while facial recognition, cameras and app connectivity may justify higher prices for some users.
Battery Type
Digital locks commonly use rechargeable lithium batteries or disposable alkaline batteries. Rechargeable batteries require periodic charging, while AA-powered models should use the manufacturer’s recommended alkaline batteries rather than heavy-duty zinc-carbon alternatives.
Warranty and After-Sales Service
Check local servicing availability, replacement-part support and whether both the door and gate locks receive the same warranty coverage.
Brand Reputation and Customer Reviews
Choose established manufacturers or retailers with a clear local support arrangement. Read recent customer reviews about long-term reliability, installation quality and repair response times rather than relying on star ratings alone.
Conclusion
For HDB homeowners, the best digital lock should make everyday entry convenient while providing dependable security.
Lockin V5 Max + V3 offers the best overall combination of premium features and price, while Yale is worth considering for its established brand and high-end capabilities. Eazea is a budget-friendly alternative, Kaadas suits family households, and Aqara stands out for Apple users.
Regardless of your budget, prioritise compatibility, safety certification and after-sales support. Being penny-wise and pound-foolish when choosing a digital lock could result in costly repairs, lockouts or avoidable security risks.
