Why Choose Door Digital Locks for your Home?

Singaporeans upgrade to digital door locks for more than convenience—they invest in stronger home security, elegant design, and enhanced property value. Whether for an HDB flat, condo, or landed property, every solution combines dependable protection with modern control.

A. Why Smart Digital Locks Are Popular in Singapore Homes

Singapore’s fast-paced lifestyle makes reliable, keyless entry highly appealing. Residents appreciate being able to enter effortlessly after work, grant access to family or helpers, and secure doors automatically without needing duplicate keys.

For HDB and condo homes, a digital lock streamlines access while maintaining safety for families and guests. Landed property owners often pair smart locks with their home automation systems for full control. Beyond convenience, a smart lock can also enhance resale appeal and aesthetic modernity.

B. Digital Door Lock Feature Categories

PIN Code Door Locks

A PIN code door lock allows entry via numeric passcodes. It’s simple, reliable, and suitable for most households. The keypad surface is easy to clean, and codes can be changed anytime for privacy.

Best for: Families or shared households needing flexible user codes.
Advantages: Reliable and low maintenance.
Limitation: May be slower to use compared to biometric access.

Fingerprint Door Locks

Fingerprint door locks scan your fingerprint for quick, secure access—ideal for busy mornings or when hands are full.

Best for: Homes with multiple occupants needing fast access.
Advantages: Instant unlocking and high accuracy.
Limitation: Finger sensors may require an occasional wipe for consistent performance.

Palm Vein Recognition Door Locks

Palm vein recognition locks identify users through internal vein patterns in the palm, offering advanced precision and hygiene since the surface doesn’t require contact.

Best for: Premium users valuing high-end biometric technology.
Advantages: Non-contact, hygienic, and virtually impossible to duplicate.
Limitation: Higher initial investment and minimal difference in daily speed compared to fingerprint systems.

Face Recognition Door Locks

A face recognition lock grants hands-free entry after scanning facial features, perfect for when carrying groceries or managing children.

Best for: Families wanting touchless convenience.
Advantages: Contactless operation and high-speed access.
Limitation: Accuracy can be affected by lighting or camera angle, so installation positioning matters.

RFID Card Door Locks

RFID card locks use contactless cards or tags to open doors with a simple tap—especially popular among elderly residents or domestic helpers.

Best for: Multi-generational homes needing easy access.
Advantages: Smooth operation and minimal learning curve.
Limitation: Cards can be misplaced; keeping spares is advisable.

App-Controlled Smart Door Locks

App-controlled smart locks enable remote access via mobile apps, allowing homeowners to unlock doors, monitor entry logs, or share temporary access securely.

Best for: Tech-savvy homeowners or those who travel frequently.
Advantages: Remote control, user management, and notifications.
Limitation: Depends on stable Wi-Fi or Bluetooth connectivity.

C. Lock Design & Form Factor Considerations

Digital locks vary in shape and operation: push-pull, lever handle, or fixed handle. Push-pull designs allow single-motion entry—ideal for high-traffic households. Lever handles provide a familiar mechanical feel, while minimalist fixed handles suit contemporary doors.

When choosing, consider your daily routines, family needs, and door type. Interlock’s fire-rated compatible digital locks ensure safety without compromising form.

D. Choosing the Right Digital Door Lock for Your Home

HDB Main Doors: Look for fire-rated locks with simple access controls such as PIN or fingerprint. Ensure compatibility with your existing handle cutout.
Condo Doors: Choose sleek models that complement architectural finishes. App-enabled locks add value for modern apartments.
Landed Properties: Opt for higher-end smart models with multi-door or remote access capability for main and interior doors.
Fire-Rated Doors: Only certified digital locks should be installed to preserve door integrity and safety compliance. Interlock Singapore offers models tested for these conditions.
