8 Best Digital Lock Shops in Singapore (August 2026)

Here is the rule, in plain terms. With effect from 1 March 2024, if you want to install a digital lock on a fire door, the lock must be certified for fire resistance. The SCDF accepts testing to two standards, SS 332 and EN 1634-1, and the resulting Certificate of Conformity can only be issued by three local certification bodies: Element Testing Services, Setsco Services and TUV SUD PSB. The lock rating must match or exceed the door rating, so a 30-minute fire door needs a lock certified at 30, 60 or 120 minutes.

There is a second requirement buried in the same guidance that I think is the more practical one. A certified lock has to include a mechanical fail-safe, meaning you can still unlock it and leave the flat if the batteries die. Every digital lock claims some form of emergency power or key override, but "claims" and "certified" are different things.

Now the qualifier, because I have seen shops overstate this. Not every HDB flat has a fire-rated main door. The requirement kicks in where your main door opens to a common corridor, lift lobby or staircase and sits close to a lift or staircase, and it is standard on many newer blocks. Older units further along a corridor may have a plain timber door. So the first thing to do is not to shop. It is to look at your own door edge for a certification label, or ask your shop to check it during the site visit. If it is fire-rated, your choice of lock is genuinely narrower than the catalogue suggests.

One more compliance note while we are here. Swapping the lock alone does not need an HDB renovation permit. Replacing the main door or its frame usually does, and the replacement has to keep the half-hour fire rating and the self-closing device. Check the current position on the HDB renovation pages before you commit to a package that bundles a new door in.

Most HDB and condo homes end up with two locks, and they are not the same product. Working out which one you actually use is how you avoid overspending by several hundred dollars.

A door lock sits on the wooden main door. It carries the heavier hardware, the biometrics and, in the premium tier, facial or palm vein recognition and a camera. It is also the one bound by the fire-rated rule above. Formats split into mortise (the full body sunk into the door edge, most secure, most drilling), rim (surface-mounted on the inside face, easiest retrofit) and push-pull (the big handle bar, best feel, priciest).

A gate digital lock sits on the metal grille gate. It is usually simpler and cheaper, and here is the thing several shops pointed out that changed how I think about this: in most HDB layouts, the gate is the barrier you actually open when you come home. The wooden door often stays open all evening. That is why a few retailers now argue you should put the better lock, and the camera, on the gate rather than the door.

Buying both as a bundle is where the money is saved, and increasingly the two talk to each other. Synchronised unlocking, where opening the gate releases the door lock at the same time, is now a standard selling point on mid-tier and premium bundles. It is genuinely convenient with hands full of groceries. It is also the feature most likely to lock you into one brand for both barriers, which is worth knowing before you buy the first one.

A digital lock in Singapore costs roughly $500 to $1,500 fully installed, and the spread inside that range is driven almost entirely by how you unlock it. Fingerprint and PIN sit at the bottom, facial recognition and palm vein sit at the top, and the middle is a long flat plateau where most people should be buying.

These are the bands I saw quoted consistently across the eight shops in August 2026. Treat them as installed prices unless a shop separates the installation fee, which a few do at $50 to $200 on top.

Two costs that do not appear on the price tag. First, a fire-rated certified lock is generally dearer than an uncertified equivalent, and if your door is fire-rated that is not an upgrade you can skip. Second, ask whether the warranty covers the callout, because a two-year parts warranty that charges $60 in transport each visit is not really a two-year warranty.

If you are looking to buy a digital lock in Singapore this month, here is the order I would work through. It is deliberately boring, and it will save you more than any promo code.

• Check your own door first. Look at the door edge or the top rail for a certification label. If your main door opens onto a common corridor near a lift or staircase, assume it is fire-rated until proven otherwise, and read the SCDF guidance on digital locksets for fire-rated doors before you shop.
• Ask for the Certificate of Conformity by name. Not "is it fire-rated", which every salesperson answers yes to, but "which certification body issued the CoC for this exact model". The answer has to be Element Testing Services, Setsco Services or TUV SUD PSB. Anything else, or a vague reference to an overseas test report, is not compliance.
• Confirm the rating matches or exceeds the door. A 30-minute door needs a lock certified at 30 minutes or higher. Mixing a 60-minute door with an uncertified lock defeats the whole point.
• Make them see your door before quoting. Every shop that impressed me does this, whether by home visit or a WhatsApp photo check. Door thickness, frame condition and gate clearance decide what fits, and a quote given without them is a guess.
• Read the warranty for the callout clause. Two years is the market floor. What separates the shops is whether labour and transport are included, and whether the installers are in-house or subcontracted.
• Test the mechanical override in the showroom. Certified locks must have a fail-safe that gets you out when the battery dies. Ask to see it work, not to be told it exists.
• Confirm whether a permit is involved. A lock swap does not need one. A new main door or frame usually does, and it must retain the half-hour fire rating and the door closer. The HDB renovation guidelines are the authority here, not your contractor.

One habit worth adopting across the whole category: almost every "best digital lock Singapore" article you will read, including the ones ranking above this page, is published by a shop that sells locks. Read them, they contain real product knowledge, but check who owns the site before you accept the ranking.

I started from the regulation rather than the product, because the SCDF requirement is the one filter that genuinely disqualifies options and almost nobody leads with it. From there I looked at every digital lock retailer that ranks for the main Singapore search terms, checked their sites directly, and dropped the ones I could not verify.

A note on what got cut. Zansan, which several older roundups still list as the largest local distributor and the only CaseTrust-accredited one, currently returns a suspended account page at its domain. Whether that is a billing lapse or something more, I am not comfortable sending you to a shop whose website is offline, so it is not on the list. That is also a decent argument for checking a retailer is actually trading before you hand over a deposit.

On ratings, I have only quoted a specific star rating where it sits on a single verifiable profile. Several shops on this list advertise five-star averages across tens of thousands of reviews, which are group totals pulled from multiple outlets and platforms. Those numbers are not fake, but they are not comparable to a single shopfront rating either, so I have described them rather than ranked on them.

Prices were taken from published price lists and promotional pages in August 2026. Digital lock pricing moves with promotions constantly, so treat the tables above as bands rather than quotes, and get your own written quote for your own door.

You need a fire-rated digital lock in Singapore if your main door is itself a fire-rated door, which since 1 March 2024 means the lock must carry a Certificate of Conformity tested to SS 332 or EN 1634-1. HDB requires a 30-minute fire rating on main doors that open to a common corridor, lift lobby or staircase and sit close to a lift or staircase, so most flats in newer blocks are covered.

The way to settle it is to look, not to guess. Fire-rated doors carry a certification label, usually on the door edge or the top rail, and they are noticeably heavier than a plain hollow-core timber door. Any competent installer will check this during the site survey. If your door is not fire-rated, you can fit any lock you like, though the compliant models are generally better built anyway.

For most Singapore households the gate lock gets used more, because the metal gate is the barrier you open coming home while the wooden door often stays open through the evening. That is why several retailers now recommend putting the feature-rich lock on the gate and a simpler one on the door, which inverts the usual sales pitch and can save a few hundred dollars.

The counter-argument is security and compliance. The main door is the actual security barrier and the one covered by the fire-rated rule, so if you are only buying one lock and your flat sits somewhere exposed, the door is the right place for it. Bundles from around $638 for both barriers make the choice mostly academic, and synchronised unlocking, where the gate releases the door at the same time, only works if both come from the same brand.

Nothing dramatic, if the lock is certified. SCDF-certified digital locksets must include a mechanical fail-safe so you can still unlock from inside and leave the flat with flat batteries, and virtually every lock sold in Singapore also has a physical key override and an emergency power contact on the outside for a power bank or 9V battery.

In practice the lock warns you first. Most models beep and flash a low-battery indicator for one to two weeks before shutting down, and a set of four to eight AA alkalines typically runs eight to twelve months in normal family use. The two habits worth keeping are to change the batteries when it first warns rather than when it stops, and to keep the mechanical key somewhere outside the flat.

Digital lock installation in Singapore takes about 45 to 90 minutes for a single lock, and most shops on this list offer same-day or next-day slots. A rim lock, which surface-mounts on the inside face of the door, is the quickest. A mortise or push-pull lock needs the door edge routed out and typically sits at the longer end of that range.

A door and gate bundle usually runs two to three hours in one visit. Installation is included in the advertised price at several retailers, while others quote $50 to $200 separately, so confirm which model you are being quoted before comparing prices. No HDB permit is needed for a lock swap on an existing door.

A $99 digital lock from a marketplace listing costs you more than a $400 one from a local shop, for three reasons. There is no local warranty you can actually claim on, no installer accountable if the routing is wrong, and, critically, almost none of them carry the SCDF Certificate of Conformity your fire-rated main door requires. Fitting an uncertified lock to a fire door compromises the door's tested performance.

The other failure mode is fit. Singapore HDB doors and metal gates have specific thicknesses and backset dimensions that generic imported locks often miss by a few millimetres, and once a door edge is over-routed you cannot undo it. If budget is the constraint, an entry-level lock from a local retailer at $299 to $459 with installation included is the safer floor.

If your HDB main door is fire-rated, and it probably is, start at Go Digital Lock, because compliance is the one thing you cannot fix later and it is the shop that treats it as the headline rather than the footnote. If you would rather buy on service history than on showroom polish, Interlock has the longest trading record and the only star rating on this page I could verify against a single profile. If you want to compare nine brands honestly with nobody pushing a house label, go to AN Digital Lock or Smart Digital Lock.

For the cleanest warranty terms, Kaadas writes labour and transport into the two years instead of leaving them for you to discover. For a resale flat needing door, gate and lock in one go, My Digital Lock has the capacity nobody else does. And if the budget for both barriers is under $700, OpenTouch gets it done properly rather than cheaply.

Whichever you choose, do the same three things: make them look at your actual door before quoting, ask which body issued the Certificate of Conformity for that exact model, and read the warranty for the callout clause. That is the whole game. For the rest of your entryway, my guides to the best window and grille contractors and the best smart home installers in Singapore cover the jobs that usually get quoted alongside this one. A lock only tells you the door is shut, so if you also want to know who was standing at it, my guide to CCTV installation covers the HDB corridor rules that changed in 2023.

One last thing. If you run a digital lock, door or home security business here, you have probably noticed that this whole category is won on content, and that the shops ranking above you are outspending you on it rather than outselling you. That happens to be my day job. Have a look at my web design services in Singapore, or get a quote and I will tell you honestly what would move the needle.
