Thinking of upgrading your HDB main door lock? Before you fall in love with any sleek digital lock on Instagram, there is one thing you absolutely must check first – is it fire-rated compliant?
In Singapore, every HDB main door is a fire-rated door. This is not just an HDB rule – it is a national safety regulation enforced by the Singapore Civil Defence Force (SCDF) and the Building and Construction Authority (BCA). The door is designed to hold back fire, smoke, and toxic gases for 30 to 60 minutes, giving your family time to escape safely.
Installing the wrong digital lock – or having an inexperienced installer drill incorrectly – can void your fire door’s protection entirely. That is a risk no Singapore homeowner should take.
In this 2026 complete guide, we have researched and ranked the 5 best fire-rated digital locks in Singapore for HDB flats – covering fire certification, access features, SGD pricing, and a step-by-step buyer’s checklist.
Quick Answer: The best fire-rated digital lock for HDB flats in Singapore 2026 is the Xeno Alexi Pro Max (premium), Zigbang SHP-P72 (most reliable), and Solity GP-6000BK (best value). All five locks on this list carry a valid Certificate of Conformity (CoC) approved for Singapore HDB fire doors.
What Is a Fire-Rated Door? (Singapore HDB Context)
A fire-rated door is specially constructed to resist fire and smoke for a rated time period – typically 30 or 60 minutes. In Singapore’s HDB flats, the main entrance door is always fire-rated as part of the building’s passive fire protection system.
According to HDB renovation guidelines, homeowners are NOT allowed to:
- Replace the fire-rated main door with a non-fire-rated one
- Drill additional holes that compromise the door’s fire integrity
- Install locks that are not certified for fire-rated door use
This is why your digital lock must come with a Certificate of Conformity (CoC) – the official document proving the lock has been independently tested and approved for use on Singapore HDB fire doors. Always ask your seller for this document before purchase.
Pro Tip (Singapore-specific): Standard HDB main door thickness is 40mm to 50mm. Always measure your door before ordering any digital lock to ensure mortise compatibility.

Frequently Asked Questions – Fire-Rated Digital Locks Singapore
Can I install any digital lock on my HDB main door?
No. Your HDB main door is a fire-rated door. You must install a digital lock that carries a Certificate of Conformity (CoC) approved for fire-rated door use in Singapore. Installing a non-compliant lock can void your fire protection and may violate HDB renovation guidelines.
What is a Certificate of Conformity (CoC) for digital locks?
A CoC is an official test certificate issued after a digital lock has been independently assessed to confirm it can be installed on a fire-rated door without compromising fire resistance. It is required for all digital locks installed on Singapore HDB main doors. Per SCDF fire safety standards, this is mandatory – not optional.
What is the standard HDB door thickness in Singapore?
Most HDB main doors are between 40mm and 50mm thick. Some older or resale flats may differ. Always measure your door before purchasing to ensure mortise compatibility.
Can a digital lock break the fire protection of my HDB door?
Yes – if incorrectly installed. Drilling too many holes or using wrong tools can damage the door’s fire-rated core. This is why using a qualified installer with HDB fire door experience is essential.
Which digital lock brand is most trusted in Singapore for HDB?
Zigbang (formerly Samsung), Hafele, and Xeno are the most established and trusted brands for HDB digital locks in Singapore as of 2026. All three have wide service networks and certified products for fire-rated door use.
How long do HDB digital locks last?
A quality digital lock should last 5 to 10 years with proper maintenance. Battery replacement is typically needed every 12 to 18 months. Most reputable brands offer 1 to 2 year warranties in Singapore.
Is digital lock installation covered under HDB renovation rules?
Yes. HDB allows digital lock installation on main doors as long as the lock is CoC certified and installed by a qualified professional. Always retain your CoC documentation for future HDB inspections. Read the full guide on the HDB official website.
