FAQ about Digital Locks in Singapore
What is the best digital lock in Singapore?
The Interlock’s Mercury X6 is our top digital lock pick in Singapore. It features a slick, curvy design and comprehensive 10-in-1 access methods—palm vein, facial recognition, fingerprint, PIN code, NFC card, smartphone app, one-time PIN, temporary passcode, mechanical key, and built-in Wi-Fi—for maximum flexibility and security.
Ideal for HDB, condo, or landed-home installations seeking both elegance and high-tech convenience, the X6’s emergency USB-C charging port and integrated tamper alarms ensure uninterrupted access and peace of mind.
What is a Smart Door Lock?
A smart door lock is an electromechanical lock with a built‑in computer that replaces a traditional keyed lock.
Instead of using a physical key, you can open it with a smartphone app, a PIN code, a fingerprint scan, or an access card. It lets you lock or unlock your door from anywhere, see who’s entered or left, and create temporary codes for visitors.
You can also connect it to other smart home devices—like cameras or voice assistants—for extra convenience and security.
Are digital locks suitable for commercial use?
Yes, digital locks are excellent for offices, stores, and warehouses. They provide secure access control and can often be integrated with existing security systems for efficient management.
What are the benefits of using a digital lock?
Digital locks offer convenience by eliminating the need for physical keys. They enhance home security and allow you to control access. Some models even let you unlock the door remotely, making them ideal for families, helpers, or guests waiting for you to get home.
Are Digital Locks Secure in Singapore?
Yes, digital locks are designed to provide high levels of security. They incorporate technologies like encryption, tamper alarms, and multi-factor authentication (e.g., double-lock features). These locks undergo rigorous safety testing and certification before being sold. To ensure maximum security, it’s important to buy from a trusted brand, set strong PIN codes and verify the lock's certifications.
For more detailed information on digital lock security, read our full guide on understanding digital locks.
Can I install a digital lock on any type of door?
Yes, digital locks can be installed on wooden, glass, and metal doors. However, it’s essential to check the compatibility of the lock with your specific door type, as different doors have different requirements.
How much does it cost to install a digital lock in Singapore?
Installation costs in Singapore typically range from $50 to $200. If you’re installing the lock on a metal door, there may be additional charges due to the extra work required.
How do I know if my door is compatible with a digital lock?
Most digital locks fit standard doors, but it’s best to review the specifications or consult your supplier to ensure compatibility. Reaching out to experts before purchasing can help guarantee the right fit.
How long do digital lock batteries last?
Most digital lock batteries last between 6 and 12 months, depending on usage. Many models will warn you when the battery is running low, giving you time to replace it.
What happens if the digital lock battery dies?
If the battery dies, most digital locks have a backup plan. You can use a mechanical key or power the lock temporarily with a 9-volt battery. Some models also allow you to recharge the lock with a USB-C power bank.
Do digital locks work without Wi-Fi?
Yes, many digital locks don’t require Wi-Fi. Features like PIN codes and fingerprint access usually work without an internet connection. Wi-Fi is only necessary for remote access and smart features. Some models also use Bluetooth instead of Wi-Fi.
Can I connect my digital lock to a smart home system?
Yes, many digital locks are compatible with smart home systems. This allows you to control them using voice commands or a mobile app. Check if the lock works with platforms like Alexa, Google Home, or Apple HomeKit.
What types of access methods do digital locks offer?
Digital locks offer multiple access methods for convenience and security. Common options include PIN codes, fingerprints, RFID cards, smartphone apps, and mechanical keys for emergencies. Some advanced models even feature facial recognition & palm vein technology.

Do digital locks require professional installation?
While some digital locks can be installed by homeowners, professional installation is highly recommended. Experts ensure proper alignment, functionality, and security, especially for advanced models or non-standard doors. Professional installers also provide guidance on optimal setup and troubleshooting.
How do I maintain my digital lock?
To keep your digital lock in good condition, clean the fingerprint sensor regularly, replace batteries as needed, and update firmware if applicable. Avoid using heavy-duty or rechargeable batteries, as they might damage the lock. Additionally, handle the lock gently and avoid slamming doors.
