Ever wished your door could recognize you? That’s the magic of a biometric lock. Instead of using a key or remembering a PIN, biometric locks use something unique about you—like your fingerprint or face—to unlock. These high-tech locks are not only secure but also super convenient, especially for today’s busy lifestyle in Singapore.
How Do Biometric Locks Work?
Biometric locks work by scanning and storing your unique physical features, such as your fingerprint, facial structure, or palm veins. When you try to unlock the door, the lock quickly compares the scanned input with the stored data. If it matches—you’re in!
Think of it as a personal password that only your body knows.
Types of Biometric Locks
Biometric locks come in different forms, each using a different part of the body for recognition. The three most common types are:
- Palm Vein Locks
- Fingerprint Locks
- Facial Recognition Locks
Let’s look at each type.
Palm vein locks – The high-security option
Palm vein locks represent the latest in biometric security technology. Unlike fingerprint or facial recognition, this method uses near-infrared light to scan the vein patterns inside your palm—something completely internal and unique to each person.
What makes palm vein locks special is their unmatched security. Because vein patterns are hidden beneath the skin, they’re almost impossible to forge or duplicate. They are also fully touchless, which makes them a hygienic and futuristic option for homeowners who want top-tier protection without sacrificing convenience.
Currently, the most advanced palm vein lock is the Xeno Alexi Pro Max. It combines palm vein recognition with other features like fingerprint, RFID, PIN, and mobile app access—all in one sleek, fire-rated model. This makes it perfect for HDB, BTO, condo, or landed properties looking to upgrade to next-level smart security.
If you’re someone who values cutting-edge technology and maximum safety for your family, the Xeno Alexi Pro Max is a powerful and elegant choice.
Fingerprint Locks – The most common type
Fingerprint locks are the most popular and widely used type of biometric lock in Singapore homes. They offer a perfect balance between convenience, affordability, and reliability.
These locks work by scanning your unique fingerprint and comparing it with the stored data. Once a match is found, the door unlocks instantly—often in less than a second. The technology is highly accurate, capable of recognizing even partial prints, making it very efficient for everyday use.
One of the biggest advantages of fingerprint locks is how easy they are to use. All it takes is a simple tap of your finger—no need to fumble with keys, remember PINs, or carry cards. Most models also allow you to store multiple fingerprints, making them ideal for families, shared flats, or anyone with frequent guests.
Whether you’re upgrading your HDB flat, BTO unit, or condo, fingerprint locks offer a reliable solution that combines smart technology with practical daily use.

Facial recognition locks – Hands-free convenience
Facial recognition locks are becoming increasingly popular in modern smart homes for one big reason: true hands-free access. These locks use advanced camera technology and AI to scan your facial features and grant access within seconds—without you needing to touch anything.
They’re especially convenient when your hands are full, like when you’re carrying groceries, holding a child, or coming home after a workout. Many models also work in both bright and low-light environments, and use live detection to ensure they can’t be tricked by photos or videos.
Facial recognition locks are an excellent choice for families with kids, elderly users who prefer no-touch operation, or tech-savvy homeowners who value seamless and secure entry. With sleek designs and powerful features, these locks add both convenience and a modern look to your door.
