"Nature Lock" Now Supports Double Locking: Unlock Two Locks Simultaneously While Maintaining Security.

Nature Inc. (headquartered in Yokohama, Kanagawa Prefecture, CEO Harumi Shiode, hereinafter "Nature"), which operates under the mission "Drive symbiosis with nature," has announced that its smart lock "Nature Lock" now supports double locking (dual locking). This update enables two "Nature Lock" units to be linked and unlocked or locked simultaneously. With this update, users can operate two locks at once simply by carrying the dedicated smart key "Nature Key" or by performing a single unlock/lock operation in the app, maintaining the original security strength of having two locks on one door while adding convenience. To commemorate this update, a special price coupon for purchasing two "Nature Lock Sets" simultaneously is available from Wednesday, June 3, 2026, to Tuesday, June 16, 2026, at 23:59.

■ Achieving a Safer and Smarter Entrance Experience with Double Lock Support

"Double locking" (also called "dual locking," "two locks," or "1 door 2 locks") is a specification that installs two locks on a single door, adopted in many condominiums and detached houses to enhance security performance.

With this update, two "Nature Lock" units can be linked and locked/unlocked together. The security strength inherent to double locks is preserved, while the inconvenience of having two keys is eliminated.

■ Development of Smartphone Hands-Free Unlocking Feature Decided

The most requested feature in user surveys after the product launch was "hands-free unlocking via smartphone." In addition to the existing hands-free unlocking with the "Nature Key," the company has decided to develop a function that uses smartphone GPS and Bluetooth communication to automatically unlock the door as the user approaches their home.

Specific specifications and release timing will be announced once decided.

■ Nature's Development Policy Rooted in User Feedback

Nature aims to provide "a smart lock experience that is easy for more people to adopt," continuing development based on user feedback.

The development of "Nature Lock" began with a user survey. In a survey of 4,725 Nature Remo users, 33.8% were aware of smart locks but answered "considered but did not buy," with the primary reason being "anxiety about being locked out due to dead batteries or malfunction." Furthermore, 44.9% of users who already had a smart lock installed continued to carry a physical key for peace of mind.

"It's convenient, but I'm worried about emergencies," "The app seems difficult to operate," "I'm not sure I can explain how to use it to my family" — from these voices and realities, the combination of the "Nature Lock" main unit with approximately 2 years of battery life and the dedicated smart key "Nature Key," which supports Apple's "Find My" app and enables hands-free unlocking, was born. The concept of "maintaining the habit of carrying a key while providing a reassuring smart lock experience" forms the core of the product.

After the launch, requests like "I want to operate it from a smartphone widget," "I want to operate it from an Apple Watch," and "I want to use it on a door with two locks" have been addressed one by one, with continuous feature development.

■ About "Nature Lock"

"Nature Lock" is a smart lock that can be retrofitted to an entrance door to make it IoT-enabled. It realizes a daily life without conscious key operation through hands-free unlocking by simply carrying the dedicated smart key "Nature Key" and auto-locking that detects the door closing and locks automatically. In addition to approximately 2 years of battery life, it is compatible with Apple's "Find My" app, providing anti-loss functionality. The hardware and firmware adopt the design and technology of "Qrio Lock," and are developed and manufactured in Japan. By linking with the separately sold "Nature Remo" series, remote operation, battery level checking, lock status confirmation, and various notification functions are also available. It also supports operation from Apple Watch and widgets, and can control two locks on a double-lock door simultaneously by linking them.
