Bringing Steve Jobs’ Aesthetic into the Real World
Playful, with a touch of CANDY HOUSE humor.
A physical take on the iOS toggle switch—perfect for quick trips like taking out the trash or checking the mailbox. The built-in temporary off switch makes it easy to leave without locking up.
Locks SESAME Every Time the Door Closes.
Open Sensor 2 detects when the door closes and sends a lock command to SESAME.
Elevate Your Security and Comfort
A minimal design. The body has evolved from a rounded shape to a slightly more angular form, allowing it to align more closely with the edge of the door for a cleaner, more streamlined look.
No reset required for OS updates or settings changes. With an updated design from the previous model, there’s no longer a need to reset the device every time you update the OS or change settings.
Uses the same CR123A battery as SESAME. Now standardized with SESAME, making it more convenient with shared battery compatibility.
Auto-lock when you need it — now smarter than ever 🎉
Locks automatically when the door closes 🔐✨
No more relying on timer-based auto-lock. With this new feature, your door locks instantly—just like a hotel.
New in this model: a button to temporarily disable auto-lock.
Perfect for quick trips like taking out the trash or checking the mailbox.
It also uses the same CR123A batteries as SESAME for added convenience 👍
Secure when you want it, off when you don’t—
making everyday life a little easier 🙆
