Linus L2 is a smart door lock designed to be fitted to the inside of an existing door. Linus L2 allows a door to be locked and unlocked through a mobile application, a separate keypad or a contactless tag reader, and the door status can be checked remotely. Two mounting plates allow attachment to many lock types and most cylinders, including doors found in Finland. The body is metal and made by precision casting. The product size was reduced by twenty percent, and a rechargeable battery pack replaces disposable cells.

- Production Technology
- Utilising advanced manufacturing techniques, the Linus Smart Lock L2 embodies cutting-edge production technology. Precision casting methods were employed to craft its fully metal design, ensuring maximum quality and durability. Additionally, state-of-the-art assembly processes were implemented to integrate the strongest motor on the market seamlessly. For a faster, quieter, world-class lock experience.
- Design Challenge
- The most daunting challenge was engineering Linus L2 to accommodate the unique door specifications in Finland. The larger door seals exert an increased sideload on the lock mechanism, to address this we shrunk the product's size by 20% while simultaneously doubling the torque to 2.5Nm. Collaborative efforts between local teams in Finland and engineering teams in Sweden and Korea resulted in a compact, high-torque solution that seamlessly integrates without compromising on quality or aesthetics.
- Project Duration
- The project started in November 2021, with collaborative efforts spanning multiple continents across the globe. Teams were strategically positioned in Korea, Sweden, and the UK to leverage their respective expertise. Internal teams from Europe, the Middle East, South Asia, and Africa ensured the product's compatibility with diverse door locks, encompassing a broad spectrum of geographical and cultural contexts. Despite these logistical complexities, Linus L2 successfully launched in March 2024.
- Operation Flow
- Turn your regular door lock into a smart one. Following simple instructions on the Yale Home App, Linus L2 will fit to the inside of your existing door with all tools needed to fit the lock included in the box. Once installed, you can lock/unlock your door using the app, the keypad (sold separately) or by tapping your phone against our new NFC reader Yale Dot. Program the lock automatically to lock/unlock, or monitor the status of your door from anywhere in the world in the app.
The Linus L2 is battery-powered and can communicate directly to mobile phones via Bluetooth and therefore would not be affected by the power being removed. The only thing that would likely no longer function is the remote functionality (unlocking the lock when away from home). However, that is just because the router/internet in the customer's house would likely stop working. - Research
- We employed a multidisciplinary approach combining design thinking, user research and technological feasibility studies using surveys, interviews, prototyping and market analysis gathered by global teams. Our insights guided the development of features such as Wi-Fi connectivity and the Yale Dot, enhancing user experience and convenience. Research informed strategic decisions, ensuring alignment with evolving market demands and sustainability goals, creating a next-generation access solution.
- Inspiration
- We wanted to expand Linus into new markets that use a 22mm Round Cylinder, to improve its performance, and to make it more sustainable. This was achieved by redesigning the motor and gear train to increase speed/torque to unlock/lock stubborn locks. Our sustainability aims were achieved by adding a rechargeable battery pack for high-power operations to remove the need for non-rechargeable cells, and by reducing the size of the product by 20% to use less material for a more sustainable product.
