Our digital lock experts review Singapore’s top-rated digital locks for smarter, safer and more convenient entry to your home or office.

Ever since I embarked on my journey to modernize my home, I’ve been fascinated by the rapid advancements in home security. Traditional locks have been the guardians of our homes for centuries, but the digital age has ushered in a new era of security: digital locks. Let’s delve into digital locks and understand why they are becoming the preferred choice for many homeowners like me.
What Are Digital Locks?
Digital locks, often called electronic or smart locks, are locking mechanisms that use electric currents to operate. Unlike traditional locks that require a physical key, digital locks can be operated using a keypad, fingerprint scanner, remote control, or even a smartphone app.
Why Choose Digital Locks?
1. Enhanced Security: Digital locks often come with features like anti-tampering alarms, auto-locking, and incorrect password alerts. This means that any unauthorized access attempts are immediately flagged.
2. Multiple Access Modes: From fingerprints to passcodes, RFID cards, and even facial recognition, the options are vast and customizable.
3. Convenience: Forget the hassle of lost keys or getting duplicates made. With digital locks, access is at your fingertips, quite literally!
4. Modern Aesthetics: Digital locks often sport sleek designs that add a touch of modernity to your home’s entrance.
This table provides a general overview of the different locking mechanisms in digital locks. Each mechanism has its own set of advantages and is suited for specific applications.

Factors to Consider When Choosing a Digital Lock
1. Type of Door: Ensure the lock is compatible with your door type, be it wooden, metal, or glass.
2. Power Source: Some locks are battery-operated, while others might need to be hardwired.
3. Integration with Other Systems: If you have a smart home system, it’s beneficial to have a lock that can integrate seamlessly.
4. Budget: Digital locks come in a range of prices, so pick one that offers the best features within your budget.
Our Digital Lock Experience: A Step into the Future
The first time I heard about digital locks, I was intrigued but sceptical. The idea of unlocking my front door without a physical key seemed both futuristic and a tad unnerving. However, after one too many instances of misplacing my keys and getting locked out, I decided to take the plunge and upgrade to a digital lock.
I opted for a biometric lock, primarily because the idea of using my fingerprint as a key felt both secure and convenient. The installation process was smooth, and the technician took the time to walk me through the features and settings.
The first week was a mix of awe and minor hiccups. I’d often find myself reaching for my keys only to remember that all I needed was my finger. But there were also moments of frustration, especially when my hands were wet and the scanner had trouble recognizing my fingerprint.
However, as the days turned into weeks, I grew more accustomed to the lock. The convenience of not having to rummage through my bag for keys, especially during rainy days or when my hands were full of groceries, was a game-changer. Plus, the added security features, like the anti-tamper alarm and incorrect attempt alerts, gave me an added sense of security.
Pros and Cons of My Biometric Digital Lock
Pros | Cons |
---|---|
High Security: The uniqueness of fingerprints means it’s challenging for someone else to gain unauthorized access. | Scanner Sensitivity: If hands are wet or dirty, the scanner might not recognize the fingerprint. |
Convenience: No need to carry or search for keys. | Battery Dependency: If the battery dies, I’d need to use the backup key or charging port. |
Multiple Users: I could register multiple family members, allowing them easy access. | Limited Users: There’s a cap on how many fingerprints the system can store. |
Modern Aesthetics: The sleek design of the lock added a modern touch to my front door. | Cost: Digital locks, especially biometric ones, can be pricier than traditional locks. |
Added Features: Features like temporary access codes were beneficial for guests. | Tech Glitches: Like all tech, there were occasional glitches and system lags. |
In conclusion, while the transition to a digital lock had its learning curve, the benefits have far outweighed the minor inconveniences. My home feels more secure, and the ease of access has simplified my daily routine. If you’re considering making the switch, I’d say go for it! Just ensure you do your research and choose a lock that best suits your needs.

Our Editor’s Review on the Samsung SHS-2920 Touchpad Digital Door Lock
Since I switched to this device, my perspective on keys and access has been revolutionized. Living without the traditional metal keys feels like a breath of fresh air.
Last November, I took the leap and installed these locks on two of my condo doors. Through varying weather conditions and temperatures, they’ve been nothing short of impeccable. And the fact that I haven’t had to replace the batteries in almost nine months speaks volumes about their efficiency.
I intentionally opted for the model without the conventional key feature. Why? The standard lock on that variant seemed susceptible to “bumping.” I was on the lookout for something sleek, unique, and a deterrent for any would-be intruder with a bump key.
Setting it up was surprisingly straightforward. Admittedly, I’m no expert on door locks, so the fact that I didn’t need to drill new holes or modify existing ones was a huge plus. After removing my old lock, I simply utilized the existing hole for the cables and affixed the lock’s interior and exterior parts where the old lock plate used to be. The provided bracket was then secured onto the door frame, ready to accommodate the deadbolt.

The lock came with three RFID key types, and I use them all. The white card-like keys are perfect for temporary access, say for guests or house help. My go-to is the key fob, which I’ve conveniently attached to my car key ring. And those sticker keys? They’re on my phone and wallet. So even on days when I’m forgetful, a simple press of my phone or wallet against the door grants me access.
And for those moments when I might leave everything behind? The pre-set code on the keypad is my saviour. For someone like me, notorious for forgetting or carelessly locking doors, this lock has been a game-changer.
It’s also a boon during my morning runs. No need for keys; my phone, equipped with my running app, doubles as my access when I return.
One feature I particularly appreciate is the automatic deadbolt activation every time I step inside. No more bedtime reminders to lock the door!
However, it’s not all roses. Two minor issues stand out. The bracket seems a tad wide for the deadbolt, making the door feel slightly wobbly when locked. To counter this, I added rubber bumpers inside the deadbolt bracket. The door now needs a bit more push, but it’s secure. My second gripe? If I have to deactivate a key (say a guest inadvertently took one), I need to reprogram all the keys, not just the one in question.
But, nitpicking aside, this is a stellar RFID lock for home use.
What Could be Improved:
- I’ve noticed that the RFID card/tag/keychain has to be practically in contact with the sensor to function. It would be more convenient if it had a range of a few inches at least.
- Additionally, the strike plate needs to be positioned incredibly close to the locking mechanism. I feel the bolt should protrude a bit more for ease.
- Building on that, the door doesn’t auto-lock unless a particular switch is fully pressed. This essentially means the back and the strike plate should be no more than half an inch apart.
- To work around this, I used a spacer where the switch meets the strike plate, creating an illusion of them being closer than they actually are.

Our Editor’s Review on the Samsung SHS-3321 Deadbolt Digital Door Lock
In my quest for a user-friendly and secure deadbolt, I stumbled upon this product after a not-so-great experience with Kevo. What caught my attention was its pick-proof design, no need for a Bluetooth connection, and the elimination of traditional keys. I have the option to use my preset code or one of the four fobs it came with. For heightened security, I can activate a dual-authentication mode requiring both the fob and code. A standout feature is its auto-lock mechanism that activates within two seconds, accompanied by a musical note, ensuring I’m aware it’s locked. The touchscreen keypad, rather than physical buttons, requires an additional step to prevent potential code detection from fingerprints: touching two random numbers before entering the actual code. The screen remains sleekly black until activated by touch, though I’m curious to see how it responds to colder hands like my wife’s.

Installation was a tad more time-consuming than anticipated, but the robust build and quality materials made up for it. The instructions could be clearer, but they were comprehensible in English. A point to note: the deadbolt extends slightly more than typical American ones, requiring minor wood chiselling. It’s crucial for the bolt to move freely for optimal function, as with all motor-driven locks. A word of caution on the bracket bolts: over-tightening can hinder the lock’s operation. This seems like a design oversight, potentially rectifiable with shims to prevent bracket compression.
Comparing it to the original Korean models from a few years back, these newer versions (post-2015) seem enhanced with clearer guidelines. My only real installation gripe was the bracket bolt sensitivity. But once adjusted, the system worked seamlessly. The sophisticated touchpad and keyless entry are a boon, especially during nighttime returns. The auto-lock feature, with its quick lock and musical confirmation, is a favourite. If needed, I can easily disable it by leaving the door slightly ajar or removing the magnet. All in all, this lock has been a valuable addition to my home security.
What Could be Improved:
- When the alarm sounds, it’s due to the auto-lock magnet doubling as a tamper sensor. It perceives any door opening without the proper inside unlock button press or the external key/pin input as a potential intrusion. To silence it, you’d typically need to use a key or pin from outside. However, I’ve found a quick workaround: just remove the battery for a brief moment.
- While this tech might have been groundbreaking about 4-5 years ago, it now feels a bit dated. Firstly, its size is rather imposing. Moreover, it lacks connectivity features – no sync with phones, Wi-Fi, Bluetooth, customer support, Samsung, Alexa, or Siri. Sure, the RF chip integration (for keychains or phones) is nifty, but there’s no way to track entries or exits. And managing access, like setting up a schedule for a weekly cleaning service, isn’t straightforward.
- Additionally, the lock has its environmental limitations. It’s not designed to withstand weather extremes, prolonged sun exposure, or even the natural oils from our skin.

Our Editor’s Review on the Samsung SHS-P717 Push Pull Digital Door Lock
I absolutely love using the key fob for entry. Just a quick wave at the keypad wakes the lock, and holding the fob close activates the sturdy deadbolts (there are two of them). A simple push on the handle, and I’m in. My wife is particularly fond of the automatic locking feature, ensuring our door is always secure. From the inside, it’s as easy as pulling the handle to exit.

While the installation and programming instructions left much to be desired, there are helpful videos online that guide you through the process. Being quite adept with tools, it took me around 4 hours for the installation, but I’m confident I could cut that time in half if I were to do it again. The lock conveniently covers any pre-existing holes in the door, though carving out the mortise lock pocket was a bit challenging.
This lock is impressively secure. I’ve tested the RFID cards for cloning vulnerabilities and found them to be safe. The random key combination feature is a smart touch to conceal fingerprints, and the side-drilled bypass key is notably challenging to pick. I’ve been using this lock for several months and am considering getting another. While programming can be a tad tricky, it’s compatible with other RFID tags. I even got some transparent ones from eBay that work perfectly and display the circuitry. One minor drawback is the slightly short deadbolt, designed to conserve battery life and the somewhat thin stainless strike plate. That’s why I opted for the double deadbolt and replaced the strike plate. Overall, I’m pleased with this lock and would recommend it, though it’s worth noting there’s no child lock feature.
What Could be Improved:
- The plastic on the door lock, when exposed to the sun and can get damaged easily
- The instructions are not very clear, but the process is pretty much self-explanatory.

Our Editor’s Review on the Samsung SHP-DP728 Bluetooth Push Pull Digital Door Lock
When I got the Samsung SHP-DP728 digital fingerprint lock, I was immediately impressed by its advanced security features and sleek design that fits perfectly with my home’s aesthetic. The fingerprint scanning is both quick and precise, granting access in mere seconds.
Installing it was straightforward, and I was amazed by its capacity to store up to 100 fingerprints – perfect for households like mine or even larger office settings. The keyless entry is a game-changer, doing away with the hassle of traditional keys. Plus, the added tamper alarm gives me an extra layer of security, notifying me if someone tries to meddle with it.

One of the standout features for me is its connectivity to a mobile app. It’s so convenient to manage and oversee the lock right from my phone, and I appreciate the real-time notifications whenever someone comes or goes.
However, the installation did create a bit of a mess with the drilling, but the installer was prepared, bringing cleaning tools and ensuring my place was spotless afterwards. Kudos to him! Using the features has been a breeze, though I’ve noticed the fingerprint unlock can be a tad finicky for those with dry fingers. Thankfully, with four unlocking options, it’s never been an issue. While the price is on the higher side, I believe it’s a worthy investment for such a top-notch product.
What Could be Improved:
- My only concern or observation is regarding the number keypad display. Ideally, the numbers should shuffle each time it’s activated to prevent potential intruders from guessing the passcode based on the oily smudges left on the glossy keypad.

Our Editor’s Review on the Samsung SHP-H20 DIY Smart Digital Door Lock
I recently got myself a compact lever lock that was a breeze to set up and came with impressive security features. It’s perfect for both my main entrance and bedroom door. I was pleased to learn that my Samsung Smart Lock adheres to the EU’s RoHS standards, ensuring minimal use of six detrimental heavy metals, including lead, mercury, and cadmium, across all its components.
One feature I particularly appreciate is the alarm that sounds if someone tries to open the door from the inside after I’ve left. And for added security, if there are more than five unsuccessful access attempts, the lock’s keypad gets disabled for three minutes.

When I input my password, the lock first asks me to press two random numbers. This clever feature ensures no one can guess my actual password by looking for fingerprint marks. And if the battery ever dies? No worries! I can simply power the lock externally with a 9V battery and gain access as usual.
Another thoughtful touch is the lock’s alert system. If the batteries start running low, it notifies me either through a distinct melody or a light on the keypad. This means I can change the batteries without having to constantly monitor their lifespan.
What Could be Improved:
- No User-friendly interface
- Does not fit the standard HDB BTO main door because it’s a small mortise lock. Can fit bedroom door only
#6: Samsung SHP-P72 Wifi Digital Smart Door Lock (previously known as SHP-DP609)

Our Editor’s Review on the Samsung SHP-P72 Wifi Digital Smart Door Lock (previously known as SHP-DP609)
I recently upgraded from the DP920 to the newer DP609 lock which is now known as the P72. This one boasts a double bolt, and I’ve noticed its fingerprint feature is much more responsive. The installation process was swift and handled with expertise. While I believe I could’ve snagged it for a better deal, the quality of the work left me content. I’d definitely give it a thumbs up.

Here’s what I love about it:
- Simplified Entry: The Push-Pull design is a game-changer. Just one move, and you’re in or out.
- Swift Fingerprint Access: The sensor is quick and spot-on every time.
- Enhanced Security with Random Codes: It prompts me to press two random numbers before my actual password. This means no one can guess my code from any visible smudges.
- Helpful Voice Feedback: The voice guide is super handy, walking me through settings and usage.
- Burglar Deterrent: With just one touch, I can activate the anti-theft feature, ensuring an alarm sounds if someone tries to exit from inside – a potential burglar’s nightmare.
- Alerts for Suspicious Activity: If the built-in IR sensor senses prolonged unusual movement, it triggers an alarm, deterring any unwanted visitors.
- High-Temperature Warning: A unique feature that caught my eye – if the lock detects unusually high temperatures (around 70°C ± 10°C, though it might vary based on where it’s installed), it sounds an alarm, flashes a warning, and even unlocks itself for a quick exit.
- Emergency Power Backup: If I ever forget to replace the batteries and they run out, I can simply connect a Micro USB 5-Pin cable from a portable charger to the lock’s external port. Then, I can use my fingerprint or password to get in.
- Quiet Mode: With kids around, or for those late-night entries, I can mute or adjust the volume of the key tones and door melodies.
What Could be Improved:
- Depending on who you buy from, the P72 may only come in Chinese language (AI speaks Chinese only); its best you clarify with your seller regarding the language
- Some users have complained that the fingerprint sensor is not sensitive enough.
- Certain sets are directly imported from China. Be aware that the Android version of the Zigbang Smart Lock app identifies these as non-local sets, while the iOS version doesn’t make this distinction.

Our Editor’s Review on the Samsung SHP-DH537 Lever Handle Digital Door Lock
When I enter my password, the system prompts me to tap two random digits, making it impossible for anyone to guess my code by looking at the smudges on the keypad. I had to make sure my door was prepped for this lock, as conventional locks might require additional drilling. Overall, I’m quite pleased with this product and its many unadvertised, handy features, though I do wish it had Wi-Fi, especially considering the price.
I can use both an RF key tag and a password to unlock the door and even combine them for double security. If I need to be mindful of my child or neighbours late at night, I can adjust or mute the key tones and door-opening melody. The orange backlit touchpad is a great help at night, and the assurance knob feature gives me peace of mind about my child’s safety.

I love the vacation mode, which triggers an alarm if someone tries to open the door from inside when I’m away. After five failed entry attempts, the lock disables itself for three minutes, and any forced entry or tampering sets off an immediate alarm. The high-temperature alarm is another excellent feature, automatically unlocking the door for a quick escape if abnormal temperatures are detected.
This lock is truly high-tech and awesome, though the latch mechanism is unique in that it doesn’t retract but folds inward only when the handle is pressed. Its modern and sleek design is appealing, but I would recommend professional installation, as it’s not easy to do on your own and is designed for doors with a single opening, not fireproof doors with two predrilled holes.
What Could be Improved:
- My only disappointment is that the cards for the door are not compatible with having my condo card access added to them
- Easy to use, but for installation, you will definitely need professional help

Our Editor’s Review on the Yale YDM7116A Biometric Digital Door Lock
I recently got the Yale YDM 7116A, a versatile digital door lock that offers access through fingerprint, PIN, RFID card, smartphone, and even a traditional key. The standout feature for me is the one-touch fingerprint scan, and now, with the updated model, I can control it using the Yale Access APP on my phone.

To my delight, it arrived sooner than anticipated. However, due to the busy season, installation took about three weeks post-delivery. Overall, I’m thrilled with my purchase and have to give a shoutout to Yale’s exceptional customer service and Andy, who did a fantastic job installing it.
I’m genuinely impressed with this lock. Once installed and set up—which, I’ll admit, took some effort—it’s been seamless. The fingerprint sensor is spot-on, and I love that I can grant temporary access to guests. The features are top-notch, and the customer service has been commendable. I’d definitely recommend it!
What Could be Improved:
Helpful to know: A buyer’s complaint:
I would like to raise a concern regarding the installation requirements for the product. The listing did not specify essential details such as the door’s clearance and thickness. It was only after making the payment that these details were requested, potentially leading to additional costs. Furthermore, even after ensuring that all requirements were met, the lock interfered with the gate handle, preventing it from closing properly.

Our Editor’s Review on the Yale YMF40A RL Digital Fingerprint Roller Mortise Door Lock
I recently got my hands on the Yale YMF40A RL, a roller mortise lock, and I must say, it’s packed with features. From fingerprint access to PIN codes, mechanical keys, and even an optional Bluetooth feature, this lock has it all. However, if you’re looking to use remote access via the Yale Home APP, you’ll need the Yale Connect Wi-Fi Bridge, which is sold separately.
What I truly appreciate about the Yale YMF40A RL is its compatibility with the Yale Home Bridge, allowing me to unlock my door from virtually anywhere.

Here’s my take on its features:
- The one-touch fingerprint verification is a game-changer for quick access.
- I love the flexibility of using a PIN code, and mechanical keys or even overriding them when needed.
- The optional Bluetooth feature is a nice touch.
- The voice guide is super helpful, especially for first-time users.
- Its smart touchpad feels modern and responsive.
- A standout safety feature is the lockout mode, which activates after five failed access attempts.

- The internal forced lock and fake PIN code features add layers of security.
- Registering my fingerprint was a breeze.
- The automatic alarm for break-ins or damage is reassuring.
- I appreciate the low-battery alert and the emergency power supply terminal.
- Being able to control the lock via the Yale Home App is convenient, but remember, you’ll need the Yale Home Bridge and Bluetooth Module from the accessory section.
- It’s also compatible with the Yale Remote Control, but you’ll need the YRM 20 N and RC 100 accessories.
All in all, this lock feels like a solid investment for home security. Highly recommended!

Our Editor’s Review on the Yale YDR3110A RFID Digital Door Lock
After trying out the YDR3110A, I’ve found it to be a sophisticated rim lock solution suitable for both homes and businesses. What stands out to me are its innovative features like alarms, the ability to set temporary PINs for guests, and the auto-lock/unlock function. I appreciate the four ways to access: using an RF Card key, a PIN code, and even through the Yale Home APP, though the mobile and remote access require additional purchases. It’s worth noting that you’ll need Yale’s team for installation.

I’m particularly impressed by the operation status notifications; the keypad cleverly communicates through number alignments. If you ever misplace a card key, you can easily invalidate it by re-registering the others. The auto-lock feature ensures the door is always secure after closing. The 80dB alarm is a great touch, activating if someone tries to tamper with the lock or during high temperatures. The low battery alert is handy, and the emergency power option using a 9V battery is a lifesaver. There’s also an optional remote control feature, utilizing advanced Wireless Floating ID technology.
What Could be Improved:
Complaints from customers:
- I wouldn’t recommend this series for a 40 mm main door. If you’re considering it for your main entrance, I’d advise looking at other digital locks. I’d even lean towards a padlock over this for my front door. To me, it feels quite fragile and seems more fitting for bedroom doors or wardrobes.
- I’ve struggled to activate the numbers using the pin option. Despite multiple attempts, the palm touch activation for the number display consistently fails. I’ve noticed this issue since I first purchased it. At first, I thought I might be positioning my palm incorrectly, but now I’m certain that the product just hasn’t met my expectations.

Our Editor’s Review on the Yale YDD724A 4-in-1 Digital Deadbolt Door Lock
