September 4, 2025

Smart locks are redefining home and business security in Singapore, offering keyless convenience, remote access, and enhanced control over who enters your space. However, with numerous options available—retrofit, full replacement, and specialised smart locks—choosing the right one can feel overwhelming.

Each type of smart lock comes with its unique features, specific installation requirements, and varying suitability for different environments. Whether you're upgrading a HDB flat, securing a private residence, or enhancing access control in a commercial setting, understanding these options is key to making the best choice.

In this guide, we’ll break down the main types of smart locks and help you decide which one suits your needs best. For trusted advice and premium solutions, SINGGATE offers a wide range of smart lock systems tailored for modern living in Singapore.

Key Takeaways

Smart locks offer a blend of convenience, control, and enhanced security. Unlike traditional locks, smart locks enable keyless access through methods such as smartphone apps, keypads, or biometrics. This means you can lock and unlock doors remotely, share digital keys with family and guests, and track access logs in real-time. They’re beneficial for busy households, rental properties, and anyone looking to upgrade home security without a complete renovation. Many models integrate with smart home systems, such as Alexa, Google Home, or Apple HomeKit, offering voice control and automation.
Choosing the right smart lock depends on your lifestyle, property type, and tech comfort. If you value remote access and monitoring, a Wi-Fi-enabled lock may be the best option for you.

Frequently Asked Questions

Do smart locks work during power outages or Wi-Fi disconnections?

Yes, smart locks are typically battery-operated, so they continue functioning during power outages. Even if the electricity or Wi-Fi goes out, you can still unlock the door using Bluetooth, a backup key, or an alternative method, such as a keypad, depending on the model. The only limitation during a Wi-Fi outage is that remote access may be temporarily unavailable. However, local unlocking and locking will still work without issues.

Can I grant remote access to guests or service providers?

Absolutely. One of the key benefits of a smart lock is the ability to create and manage digital keys. You can grant temporary or scheduled access to guests, cleaners, babysitters, or delivery personnel through the smart lock’s companion app. You can also set expiration times or specific entry windows, and revoke access at any time. This eliminates the need to duplicate keys or hide them under doormats.

How long do the batteries in a smart lock last?

The battery life of a smart lock varies by brand and usage, but most models last between 6 and 12 months on standard AA or CR123A batteries. Locks that use Wi-Fi tend to consume more energy, while Bluetooth-only models are more efficient. The app usually notifies you well in advance when battery replacement is needed. Some premium models also show battery percentage within the app interface for easy monitoring.

Are smart locks suitable for HDB or condo units?

Yes, smart locks are suitable for HDB flats, condominiums, and landed properties alike. However, in Singapore, it's important to choose models that comply with local fire safety and door type regulations. Many smart lock brands offer models specifically designed for metal or wooden HDB main doors and gates. Always check with your town council or property manager to ensure your installation complies with any housing rules.

Can smart locks be hacked?

While no system is entirely immune to hacking, reputable smart lock manufacturers design their devices with robust security measures, including end-to-end encryption, two-factor authentication (2FA), and regular firmware updates. To reduce risks, it’s important to purchase smart locks from trusted brands, use strong passwords for your accounts, and keep your mobile devices secure. Avoid purchasing locks without industry-standard security certifications.
