How to Choose a Digital Lock in Singapore

Match the lock to your door. HDB main doors take most models in this collection. For condo doors, check the door thickness first, as most locks fit 35 to 55mm. If you also want your metal gate secured, a door and gate bundle saves $100 or more versus buying separately, and both locks can share one app.

Pick your unlock methods. Fingerprint and PIN cover most households. Face recognition suits families with elderly members or kids whose fingerprints read poorly. Every lock here keeps a mechanical key backup and supports emergency power from outside, so a flat battery never locks you out.

Price guide. Entry models from $369 handle fingerprint, PIN and card access. Mid-range models from $550 to $899 add app control and better build quality. Flagships from $900 up bring face recognition, palm vein or camera viewers. Not sure which tier fits? See our digital lock brand rankings or WhatsApp us for a quick recommendation.

FAQ for Digital Door Locks for Singapore Homes

Q1. What is a digital door lock?

A digital door lock allows you to access your property without traditional keys, using methods like PIN codes, fingerprint recognition, RFID cards, or mobile apps. These locks are ideal for enhancing security and convenience, as they often include features like auto-locking, tamper-proof technology, and remote access.

Q2. How do I install a digital door lock?

Most digital door locks are installed by the retailer's technicians at time of purchase — no separate contractor needed. Installation takes 1-3 hours. The technician drills the mortise cavity if needed, fits the lock body, sets up your fingerprints, PIN codes and cards, and walks you through emergency access (9V backup, mechanical key override). Always confirm your door type first — HDB fire-rated doors, condo solid-core doors, and landed property doors as each have different fitting requirements. At Interlock, We offer professional installation services, with over 17 years of experience. Our team ensures that the lock is properly fitted and calibrated for your door. We also provide basic usage training to help you get started.

Q3. What if my digital door lock battery runs out?

Many of our digital locks come with a backup USB-C charging port, so you can still access your home even if the battery is drained. Additionally, some models have manual key access for emergencies, ensuring you are never locked out.

Q4. Are digital door locks compatible with smart home systems?

Yes! Our digital door locks integrate with major smart home platforms including Apple HomeKit, Google Home, Amazon Alexa, and Matter-compatible ecosystems, allowing you to control and monitor your lock via voice commands, the Apple Home app, or your mobile device.

Q5. Is a smart door lock worth it?

Smart door locks offer a high return on convenience and security. They eliminate key-related hassles and provide features like fingerprint unlocking, PIN codes, remote access, and activity logs. For homes and businesses, they significantly reduce the risk of lost keys and unauthorised access, making them a practical upgrade over traditional locks.

Q6. Can smart locks be installed on any door?

Smart locks can be installed on most standard doors, including wooden, metal, and even glass doors with the right models. However, door thickness, backset size, and compatibility with existing hardware (e.g. mortise or deadbolt cut-outs) must be checked. Brands like Interlock offer models tailored for glass, sliding, and wooden doors in Singapore.

Q7. What is the best digital door lock to buy in Singapore?

The best smart digital door lock depends on your door type and features needed. For example, Interlock’s Mercury X6 offers facial and palm recognition , making it the most advanced and high tech smart lock in the market, while Aqara A100 is ideal for HDB with its fire rated capability and apple homekit access. For glass or sliding doors, the Mercury GD1 is a top option. Choose based on security level, user access options, and design compatibility.

Q8. What are the disadvantages of smart locks?

While smart locks are secure and convenient, they rely on battery power or connectivity. Batteries must be replaced periodically, and poor Wi-Fi or outdated firmware can cause reliability issues. Strong passwords and updated apps are essential to prevent digital vulnerabilities. In rare cases, weather exposure can also affect performance on unsheltered doors.

Q9. Is a PIN code or biometric lock better?

PIN code locks are reliable and work for all family members with a 100% entry rate. Biometric locks (fingerprint, palm vein, face recognition) are faster for daily use and eliminate the need to remember codes. For most Singapore households, a lock that supports both, using fingerprint/face recognition as the primary method and PIN as a backup, offers the best balance. If you have elderly family members or young children, RFID cards are often easier than either.

Q10. What digital lock brands are available in Singapore?

Top digital lock brands in Singapore include Interlock Mercury, Aqara, Samsung (Zigbang), Gateman, Lockin, and Solity. Interlock Singapore carries all major brands with professional installation and after-sales service.
