13 Best Smart Digital Door Locks: With door camera & face recognition

I just moved into my newly renovated 4-room resale HDB unit with my partner and our newborn baby. The first few months were particularly challenging for us, as we eased into the home using the default HDB door lock that unlocks with keys.

We were terrible with our keys and security and we even had instances where our keys were left at the main door lock - overnight!

Goodbye to getting locked out of your house when you misplace your keys. Beyond the convenience of going keyless, a smart door lock ensures that your home is always secure with the auto-lock function and security alarm. Here are our top picks of the best digital door locks from deadbolt, rim, and mortise lock mechanisms.

Yale YDR50GA + YDR41A Digital Door Lock, $999

The Yale YDR50GA (Gate) + YDR41A (Door) bundle is a classic “retrofit” solution widely popular in Singapore and Malaysia. It is designed specifically for public housing (HDB) and apartment setups that feature a metal gate in front of a wooden main door.

This bundle is a “workhorse” pairing. It does not offer the futuristic aesthetic of the premium Push-Pull locks (like those from Samsung or Philips), but it prioritises reliability and compatibility with older metal gate structures. Below is an analysis of its performance, pros, and cons.

The YDR50GA is the star of this bundle because finding a high-quality digital lock for metal gates is notoriously difficult. Its primary strength is its metal-gate specific design. Unlike standard locks that require custom metal boxes to be welded onto your gate, the YDR50GA is designed to clamp onto existing gate bars. It uses a “jimmy-proof” vertical bolt mechanism, which is significantly harder to pry open than a standard horizontal latch.

However, the user experience has some friction. While it supports fingerprint, PIN code, and RFID cards, the fingerprint sensor is located on the front panel. Depending on the spacing of your metal gate bars, accessing the sensor can sometimes feel cramped for users with larger hands. Additionally, because the unit is exposed to the corridor environment, it requires more frequent cleaning of the scanner to maintain sensitivity compared to the indoor unit.

The YDR41A is a “Rim Lock,” meaning it is a surface-mounted unit that sits above your existing door handle. The major advantage here is cost-effective upgrading. You do not need to remove your current door handle or mortise latch; this lock simply adds digital security to the door. It is compact, reliable, and features Yale’s “one-touch” fingerprint verification, which is generally fast and accurate.

The downside is largely aesthetic and ergonomic. Because it is a Rim Lock, it does not replace your door handle. You still need to unlock the digital unit and then physically turn your existing mechanical lever to open the door. This feels less “premium” than modern Push-Pull locks (like the Yale YMI70 or Philips 9300), where the unlocking and opening action is a single fluid motion.

The “Smart” aspect of this bundle comes from the Yale Access (or Yale Link) ecosystem. When paired with the Yale Connect Wi-Fi Bridge (often sold as an optional add-on, so do check if your bundle includes it), you can control both locks from your mobile phone.

The most advertised feature is the synchronised unlocking. In theory, unlocking your gate can automatically trigger the door lock to open, allowing for a seamless entry. In practice, this relies heavily on the Bluetooth signal strength between the two locks. If your gate and door are thick or far apart, the synchronisation can occasionally lag. However, for most standard HDB setups, it works reliably enough to be a major convenience.

For under $1,000, this gate and door digital lock is a steal — you’ll also get freebies with this purchase, including a free Yale Receiver Module, and a Yale Acess Module.

Yale YDR50GA Gate + YDR41A Digital Door Lock is priced at $999 from Lazada.

Philips EasyKey Alpha Digital Door Lock, $1,488

The Philips EasyKey Alpha is one of the most recognisable “Push-Pull” digital locks in the Singapore market.

Unlike the Yale rim lock or traditional lever locks where you must “grip and turn,” the Philips Alpha uses a Push-Pull mechanism. To enter, you scan your fingerprint and simply push the door open in one fluid motion. To exit, you pull the handle. This ergonomic design is its defining feature, reducing the physical effort required to open a heavy door.

The “scan and push” motion is exceptionally intuitive. It is particularly useful if you are carrying heavy groceries or a sleeping child—you can nudge the door open with your body or elbow once unlocked.

The Alpha employs a fully automatic mortise. As soon as you close the door, the deadbolt instantly pops out to lock it. There is no need to lift a handle or wait for a motor to wind; it is immediate and secure. Because it drives a heavy mechanised mortise, it consumes more power than a simple rim lock. You may find yourself changing the 4–8 AA batteries every 6 to 9 months depending on usage.

Out of the box, the lock often only supports Bluetooth. If you want to unlock the door remotely for a delivery person while you are at work, you typically need to purchase a separate Wi-Fi bridge/gateway. Many cheaper competitors include this feature as standard.

Philips EasyKey Alpha Digital Door Lock is available at $1,488 on EAZEA.

Kaadas K9-5W Digital Door Lock, $839

The Kaadas K9-5W is essentially the direct rival to the Philips EasyKey Alpha, but it plays a slightly different card to win you over: value-added connectivity. While the Philips Alpha focuses on pure ergonomic luxury, the K9-5W focuses on being “smart” right out of the box without needing extra accessories.

The “5W” stands for Wi-Fi. The original Kaadas K9 was a solid push-pull lock but lacked remote connectivity. The K9-5W fixes this by integrating a Wi-Fi module directly into the lock’s body. You do not need to buy an additional “bridge” or plug a dongle into a nearby wall socket to get it online. It connects directly to your home router.

The integrated Wi-Fi (No Hub Needed) function is its biggest advantage over the Philips Alpha. You can check lock records, generate temporary PIN codes for visitors, and receive push notifications immediately after installation. It is a cleaner, less cluttered setup.

Kaadas K9-5W Digital Door Lock is priced at $839 from Shopee.
