Upgrading to a digital lock for your HDB isn’t just about ditching your keys—it’s about staying safe. In Singapore, most HDB main doors are fire-rated door. This means any lock you install shouldn’t just look good; it needs to be installed without compromising the door’s ability to hold back a fire.
If you’re wondering which smart locks are actually safe for your fire-rated door, here are the top five picks for 2026.
1. Xeno Alexi Pro Max Digital Lock
The Xeno Alexi Pro Max is the powerhouse of 2026. It’s a favorite for HDB owners who want “future-proof” security without touching a single surface.
- The Fire-Rated Edge: Officially CoC (Certificate of Conformity) tested and Approved to withstand high heat for up to 60 minutes, ensuring your HDB fire door remains compliant.
- The Tech: Features 3D Face Recognition and Palm Vein tech—it reads the unique vein patterns under your skin, making it nearly impossible to spoof.
- Pros: 8-in-1 access modes; built-in 4-inch indoor screen to see who’s outside; dual-battery system for zero downtime.

4. Aqara D100 Zigbee Digital Lock
The Aqara D100 is the top choice for “Smart Home” enthusiasts, especially those using Apple HomeKit.
- The Fire-Rated Edge: Fully fire-certified for HDB main doors, blending high-end aesthetics with legal safety compliance.

5. Solity GP-6000BK Digital Lock
Solity is Korea’s largest digital lock manufacturer, and the GP-6000BK is their best-selling “value-meets-performance” model in 2026.

- Pros: Highly affordable for the features; supports Dual Unlocking (syncs with your Solity gate lock to open both at once).
- Cons: Wi-Fi capability is often an optional add-on rather than built-in.
Why the “Fire-Rated” Part Actually Matters
Your HDB door is designed to hold back smoke and flames for 30 to 60 minutes. If an installer drills too many holes or uses the wrong tools, they can effectively “break” that protection.
When buying, keep these 3 things in mind:
- Door Thickness: Most HDB doors are 40mm–50mm. Double-check your lock supports this.
- The Installer: The lock is only as safe as the person installing it. Ensure they are experienced with HDB fire-rated requirements.
- Unlock Methods: If you have elderly parents, fingerprints might be hard for them (as skin thins with age). In that case, look for RFID cards or easy PIN pads.
Final Thoughts
Upgrading your home is exciting, but don’t sacrifice safety for a cool gadget. All five of these locks are great choices, but the “best” one is the one that fits your budget and is installed by a pro who knows how to keep your fire rating intact.
