The range spans classic keypad locks, push-pull handle models and premium 3D face-recognition units, so there is more choice than first appears. This guide walks through the Kaadas digital lock line-up as sold and installed in Singapore, weighing unlock methods, security features, battery life and door compatibility. We frame everything for local doors, HDB and condo alike, and prices in indicative SGD, and we flag the practical points, fire-door fit, battery backup, installation, that decide whether a lock becomes a daily convenience or a nagging frustration.
What to look for in Singapore
- Confirm the Kaadas model is certified for your door, whether an HDB fire-rated main door, a condo door or a metal gate.
- Choose the unlock methods you will actually use, from fingerprint and PIN to card, app or face recognition.
- Prioritise a fast, accurate fingerprint sensor, since a fussy reader is the most common everyday annoyance.
- Check battery life and that the lock gives ample low-battery warning with an emergency power option.
- Look for scheduled or one-time PIN codes if you need to let in helpers, relatives or guests.
- Decide whether you want app and remote features, and confirm they work reliably on your home connection.
- Prioritise auto-lock and anti-tamper alerts so the door secures itself if someone forgets.
- Buy and install through an authorised Kaadas dealer so fit, warranty and after-sales are handled locally.

Best Value
Kaadas keypad digital lock
The keypad Kaadas is the value pick for households that want reliable fingerprint and PIN entry without paying for a push-pull handle or face recognition. It keeps the fast sensor and a physical key backup, and the slimmer body suits doors where a push-pull unit would be overkill. You give up some of the flashier features, but the core daily experience of tapping a code or fingerprint is just as smooth. For a straightforward, dependable lock on a budget, it delivers the essentials well.
Pros
- Reliable fingerprint and PIN
- Physical key backup
- Sensible price
Cons
- Fewer premium features
- No push-pull convenience
Premium
Kaadas 3D face-recognition lock
At the top of the range, the Kaadas 3D face model unlocks as you approach, reading your face for genuinely hands-free entry, which is a real luxury when your arms are full of groceries or a child. It retains fingerprint, PIN and app options as backups, and the 3D sensing is harder to fool than a flat camera. It commands a premium price and a larger body, so it suits households that value convenience highly. For the most effortless entry experience, this is the flagship to consider.
Pros
- Hands-free face unlock
- Multiple backup methods
- Secure 3D sensing
Cons
- Highest price in the range
- Bulkier unit
Best for X
Kaadas slim gate lock
For HDB homes that want to digitise the metal gate as well as the main door, the slim Kaadas gate model fits the narrow gate frame while still offering fingerprint and PIN entry. That means you can leave the gate unlocked by a tap rather than a key, which is a genuine daily convenience. It pairs neatly with a push-pull or keypad Kaadas on the main door for a fully keyless entrance. If your setup includes a gate you use often, this completes the picture.
Pros
- Fits slim gate frames
- Fingerprint and PIN entry
- Pairs with a main-door lock
Cons
- Gate-specific, not for main doors
- Smaller battery capacity
The verdict
The Kaadas push-pull digital lock is the best all-round choice for most Singapore front doors, balancing a fast fingerprint sensor, multiple unlock methods and strong local support. Step down to the keypad model to save money, up to the 3D face-recognition flagship for hands-free entry, or add the slim gate model to digitise your HDB gate.
Frequently asked questions
Is Kaadas a good digital lock brand for HDB flats?
Yes, Kaadas is one of the most established digital lock brands in Singapore, with models certified for HDB fire-rated main doors and a wide local dealer and service network. Its fast fingerprint sensor and multiple unlock methods suit local households well. Because so many flats already use Kaadas, installation and after-sales support are well understood here. For an HDB main door, it is a safe, popular and dependable choice.
Can Kaadas locks fit HDB fire-rated doors?
Yes, Kaadas offers models specifically certified for HDB fire-rated main doors, but you must choose a compatible model and have it fitted by an authorised technician who will not compromise the fire rating. The dealer should check your door before installing. Proper installation also keeps the warranty valid. Always confirm the specific model is fire-door certified rather than assuming any Kaadas lock will fit your door.
What happens if my Kaadas lock runs out of battery?
Kaadas locks give clear low-battery warnings well in advance, and most include an emergency power option so you can touch a battery or power bank to a terminal and unlock to swap the batteries. Many models also keep a physical key override. Batteries typically last many months, so being locked out is easily avoided by heeding the alerts. Keep spare batteries at home as a simple precaution.
Can I give my helper or guests their own access?
Yes, Kaadas locks let you register additional fingerprints or issue separate PIN codes for family, helpers or guests, and connected models can manage or revoke access from the app. Some models support scheduled or one-time codes for temporary visitors. This means no copied keys and easy control over who can enter. It is one of the main day-to-day advantages of moving to a Kaadas digital lock.
Is the 3D face-recognition model worth the extra cost?
It is worth it if you highly value hands-free convenience, since the lock reads your face and opens as you approach, which is a genuine help when carrying groceries or children. The 3D sensing is also more secure than a simple camera. For households happy to tap a fingerprint, the extra outlay is not essential. Decide based on how much you value effortless entry versus the premium price and larger body.
