Connected locks, which allow users to unlock doors using smartphones, smartwatches, or voice assistants, are still relatively uncommon in France compared to their popularity in parts of Asia. However, new models are beginning to appear in Europe, offering features that appeal to homeowners and property managers. One of the main advantages of these locks is their ability to eliminate the need for physical keys, making it easier to manage access for seasonal rentals or accommodations listed on platforms like Airbnb. Some models even allow remote access, enabling property owners to grant or revoke entry without being physically present. Among the top options for home use is the Nuki Smart Lock Ultra, a high-end product that can be installed by replacing the existing lock cylinder. It supports multiple unlocking methods, including smartphone, smartwatch, or a traditional key, and offers a detailed app for managing access with temporary or permanent user permissions. The lock is known for its speed and quiet operation, with a locking and unlocking time of just 1.5 to 2 seconds. While it is considered a universal and high-quality product, it comes with a higher price tag. For those looking for a more affordable option, the Nuki Smart Lock Pro provides similar features with easier installation and a lower price. The Yale Linus 2 Lite is another budget-friendly choice, priced under 140 euros, and features a compact, stylish design. It can be installed without replacing the cylinder in some cases, though it is slower and noisier than high-end models and lacks built-in Wi-Fi. The Yale Linus Smart Lock is compatible with 95% of existing locks and uses the existing cylinder for installation, but it is bulkier and runs on 4 AA batteries. Other models like the SwitchBot Lock Pro and the Igloohome Smart Deadbolt are tailored for specific needs, such as ease of installation or compatibility with vacation rental platforms. The Igloohome model, for example, allows for remote access codes and integrates with Airbnb booking calendars, making it ideal for short-term rentals. While most connected locks offer a physical backup key and can function during power or internet outages, their security is generally comparable to traditional locks, though they may have vulnerabilities. As the market evolves, compatibility with smart home ecosystems like Google Home, Apple HomeKit, and Amazon Alexa is becoming increasingly common, though buyers should verify compatibility before purchasing.
