Introduction
Upgrading to a digital lock is one of the most popular home improvements for Singapore homeowners — but if you live in an HDB flat, BTO unit, or condo, it isn’t as simple as picking whichever lock looks good online. Since fire-rated main doors are standard across most HDB and BTO homes, the lock you install has to meet specific SCDF (Singapore Civil Defence Force) safety requirements — or you risk a failed inspection, a voided warranty, or worse, a real safety gap in an emergency.
This checklist breaks down exactly what’s required, so you can shop with confidence and install without compliance headaches.
Why Digital Lock Compliance Matters
Most HDB main entrance doors are fire-rated doors, tested to contain fire and smoke for a set duration (typically 30 minutes) to protect residents during an evacuation. When a digital lock is fitted onto a fire-rated door, the lock itself becomes part of that fire safety system — which means it has to be tested and certified to the same standard as the door, not just chosen for looks or features.
An uncertified lock can compromise the door’s fire rating, which matters for three reasons:
— a non-compliant lock may fail or jam in a fire, blocking evacuation
— HDB and SCDF inspections can flag non-compliant installations
— claims can be affected if a non-compliant modification contributed to fire spread
The 2026 Compliance Checklist
Use this as your quick-reference guide before you buy or install a digital lock.
1. Confirm the Lock Is Fire-Rated
Not all digital locks sold in Singapore are fire-rated, even if they look identical to compliant models. A genuine fire-rated digital lock is built and tested to withstand high heat without failing, so it doesn’t compromise the door during a fire.
2. Check for a Valid Certificate of Conformity (CoC)
This is the single most important document. Digital locks installed on fire-rated doors in Singapore must carry a CoC issued by an approved local certification body, confirming the lock meets recognised fire testing standards (such as SS 332 or EN 1634-1). Ask your retailer to show this before you buy — a legitimate seller will have it ready.
3. Verify the Certifying Body
The CoC should come from a government-approved certification body (for example, SETSCO or an equivalent accredited body). If a seller can’t name who issued the certificate, treat that as a red flag.
4. Match the Lock to Your Door, Not Just Your Taste
Fire-rated doors and their approved locksets are often tested and certified as a matched set. Swapping in a lock that wasn’t tested with your specific door type can technically void the compliance of the whole assembly, even if the lock itself is certified.
5. Use Professional Installation
Improper installation — excessive drilling, damaged seals, removed intumescent strips — can compromise a door’s fire rating even with a fully certified lock. Professional installers know how to fit a lock without damaging the door’s fire-resistant core or seals.
6. Keep the Mechanical Override
Every compliant digital lock should include a physical key override for emergencies, power failure, or app malfunction. Never install a lock that removes this fail-safe entirely.
7. Don’t Tamper With the Door Closer
If your unit has a door closer fitted as part of the fire door assembly, it’s there by requirement — not preference. Removing or disabling it (even to keep the door open for convenience) is a fire safety violation, separate from the lock question but often flagged in the same inspection.
8. Keep Your Documentation
Retain your CoC, installation receipt, and any warranty documents. If HDB, your management corporation, or an insurer ever asks for proof of compliance, you’ll want this on hand — especially useful during resale.
Quick Reference Table
| Requirement | What to Check |
|---|---|
| Fire rating | Lock explicitly marketed and tested as fire-rated |
| CoC | Valid Certificate of Conformity from an approved body |
| Standard | Meets SS 332 or equivalent fire testing standard |
| Installation | Done by a professional, door seals undamaged |
| Override | Physical key backup included |
| Door closer | Left intact and functional |
| Documentation | CoC and receipts kept for records |
BTO Homeowners: What to Know Before Key Collection
If you’re moving into a new BTO, this is the ideal time to plan your digital lock upgrade — before renovation works begin, so your locksmith can coordinate installation around your door works rather than around your existing setup. Choosing a certified fire-rated lock from the outset avoids a costly rework later if HDB flags a non-compliant installation during a routine check.
