A fire rated smart lock matters more than most buyers realise in Singapore, because HDB main doors are fire-rated by design and fitting a non-compliant lock can compromise that protection. A properly fire-rated digital lock keeps the door’s fire integrity intact while giving you fingerprint, PIN and card access, so you get modern convenience without cutting corners on safety. This guide explains what fire-rating means for your door and compares the trusted families that offer certified fire-rated models here.
This is for HDB and condo owners who want a keyless main-door lock that respects their fire-rated door, and who want honest guidance on certification rather than marketing claims. We focused on brands with genuinely fire-rated (or fire-rated-compatible) locks and local support, weighing unlock methods, build quality against our humidity, and value in SGD including proper installation. As always, our recommendations are independent, and the SGD prices quoted are indicative ranges that change often, so confirm the latest price and the exact fire rating before you commit. The single most important step is to have an authorised dealer verify that your chosen model suits your specific HDB door, because a correctly fitted fire-rated lock protects both your security and your safety in an emergency.
What to look for in Singapore
- A model specifically rated or certified as fire-rated compatible, so it does not void your HDB main door’s fire integrity.
- Confirmation from the authorised dealer that the lock suits your door’s fire rating and thickness before installation.
- Heat-resistant internal components and a mortise (rather than surface-only) design common on fire-rated locks.
- Reliable unlock methods, typically fingerprint, PIN, card and a mechanical key backup for emergencies.
- A humidity- and rust-resistant finish suited to our climate and open corridors.
- Auto-lock and anti-peep PIN for everyday HDB corridor security.
- Battery life of 6 to 12 months with a low-battery warning and emergency power backup.
- Local warranty, professional installation and a dealer who understands fire-rated door requirements.

Frequently asked questions
Do I need a fire-rated smart lock for my HDB flat?
HDB main doors are fire-rated, so fitting a lock that is fire-rated or certified fire-rated compatible preserves that protection and keeps you compliant. Always confirm with the authorised dealer that the specific model suits your door’s fire rating and thickness before installation.
Does installing a digital lock void my HDB door’s fire rating?
It can if you fit a non-compliant lock or drill improperly, which is why choosing a fire-rated model and a dealer experienced with fire doors matters. A proper fire-rated mortise lock installed correctly maintains the door’s integrity.
Which brands make fire-rated smart locks in Singapore?
Yale, Kaadas, Samsung, Philips and Hafele all offer fire-rated or fire-rated-compatible digital locks sold and installed locally. Ask the dealer to point out the fire-rated models specifically, as not every model in a range carries the rating.
Are fire-rated locks more expensive than normal digital locks?
Usually a little, because of the mortise construction and heat-resistant components, with fire-rated models typically ranging from $400 to $1,000 in SGD installed. The extra outlay buys genuine compliance and safety for your main door, which is well worth it.
How do I know if my HDB door is fire-rated?
HDB main doors are fire-rated by design, and you can often see a label or certification on the door edge, though your installer can confirm this during a site visit. Because of this, always ask the dealer to fit a fire-rated model and install it without compromising the door’s integrity. If in doubt, request written confirmation that the chosen lock suits your specific door’s fire rating before installation goes ahead.
