29 May 2024 | BY

What type of digital door lock would best fit your comings and goings: Pin code, fingerprint, RFID, or smart locks?


Gone are the days of fumbling for keys or worrying about getting locked out of your home. Digital door locks are becoming increasingly popular in Singapore, but with so many different types on the market, trying to decide on the right one can be overwhelming.

This guide will compare the 4 main types of digital door locks: pin code, fingerprint, RFID, and smart locks. So, whether you prioritise convenience or smart home integration, you’ll be well-equipped to choose the perfect digital lock for your needs.

Pin Code Locks

For those seeking a balance between convenience and security, pin code locks are a compelling option. These digital locks can be unlocked by entering a personalised code on the keypad, eliminating the need to carry around physical keys.

Beyond convenience, pin code locks boast enhanced security compared to traditional locks. Their pick-proof design makes them more resistant to break-ins, offering peace of mind for homeowners. Additionally, you can program unique pin codes for family members, roommates, or trusted individuals, granting them access without compromising overall security.

However, it’s important to consider potential drawbacks. Pin codes can be vulnerable to social engineering, where someone tricks you into revealing your code. Similarly, someone watching you enter the code could potentially gain access. Another consideration is forgetting your code. While some locks offer backup key options or allow for resetting the code from inside the house, getting locked out due to a forgotten code can be quite the hassle.

Samsung SHP-DP728

You can purchase the Samsung SHP-DP728 from authorised retailers like My Digital Lock and AN Digital Lock at a price point of around $860.

Fingerprint Locks

For a step up in convenience, fingerprint locks are a popular option. Similar to unlocking a smartphone, utilising fingerprint recognition technology eliminates the need to remember a code.

Picking or copying fingerprints is also practically impossible, which adds an additional layer of security.You can also program fingerprints for family members, roommates, or trusted individuals.

Unfortunately, fingerprint sensors may not always recognise fingerprints perfectly, especially if they’re wet, dirty, or damaged. This can lead to multiple scan attempts being necessary to unlock the door.

Like any electronic device, fingerprint locks also rely on batteries and internal electronics to function, so malfunctions or dead batteries can result in lockouts. Do note that fingerprint locks generally come at a higher price point as compared to pin code locks.

RFID Locks

Typically installed in offices and other non-residential buildings, RFID locks prioritise touch-free unlocking. Simply wave your keycard or fob near the reader, and the door unlocks–-an ideal for those who frequently carry bags or groceries. 

Similar to other digital locks, RFID systems allow you to program access for multiple users by assigning them individual keycards or fobs. This eliminates the need for physical keys for each person. Additionally, temporary keycards can be issued for guests, service providers, or movers which can be easily deactivated when access is no longer required.

However, a potential downside is lost or stolen credentials. A missing keycard or fob could grant unauthorised access unless a backup plan, like a physical key or secondary unlocking method, is in place. While uncommon for residential use, it’s worth noting that advanced hacking techniques could exploit vulnerabilities in the RFID system.

Smart Locks

Smart locks offer the ultimate level of convenience with smartphone app control functions. You can lock and unlock your door remotely, track who enters and exits your home, and even receive alerts when the door is unlocked.

However, a stable internet connection and a functioning smartphone app with full battery are essential for operation, which can be troublesome after a long day out. Smart locks also generally come at a higher price point, as compared to traditional locks or even other digital lock options.
