Why smart locks fail with multi-point locking systems.

Multi-point locking doors present smart locks with 3 insurmountable problems. Most manufacturers offer only expensive compromises or give up.

Most brands like FUHR, ROTO, and MACO require full lock body replacement for smart upgrades. Beyond the high price of new hardware, professional electricians are needed alongside locksmiths to install hardwired systems, driving labor costs sky-high.

Yunity’s Fix: Engineered specifically for MPL doors, it fits standard screw hole spacing universally. Its removable lithium battery eliminates the need for electrical wiring, cutting installation time and costs dramatically.

Over time, doors and lock bodies warp or develop bolt jams, requiring higher torque to operate. Most smart lock solutions lack the power to overcome these issues, leading to frequent malfunctions.

Yunity’s Fix: Equipped with a high-torque motor, it effortlessly handles stuck bolts and warped doors, ensuring reliable operation even on aging entryways.

Different MPL systems have unique cylinder rotation angles, making manual calibration tedious and error-prone—misalignment results in failed operation. Additionally, bulky smart lock panels often interfere with existing door handles.

Yunity’s Fix: Its automatic calibration technology adapts to any MPL rotation angle instantly. With a slim design matching standard escutcheon sizes, it fits seamlessly without interfering with original handles.

Frequently asked questions

Everything you need to know about Yunity

Does Yunity really work with my heavy multi-lock?

Yes! Yunity is designed to work seamlessly with heavy multi-lock systems. Our advanced motor technology provides sufficient torque to handle even the most robust locking mechanisms found in security doors and gates.

Do I really need to drill?

In most cases, minimal drilling is required for secure installation. However, we also offer adhesive mounting options for renters or those who prefer not to drill. The drilling method ensures the most stable and long-lasting installation.

How long do the batteries really last?

Yunity's batteries typically last 8-12 months with normal usage (8-10 unlocks per day). The actual battery life depends on usage frequency and environmental conditions. You'll receive low battery notifications well in advance through the app.

What happens when the battery is empty?

Don't worry! Yunity features a backup micro-USB port that allows you to power the lock temporarily with a portable power bank. Additionally, you can always use your traditional key to unlock the door manually.

Is Yunity weatherproof?

Yes! Yunity is rated IP65 weatherproof, meaning it's protected against dust and water jets from any direction. It can withstand rain, snow, and extreme temperatures, making it suitable for outdoor installation.

Do I need the Wi-Fi Bridge?

The Wi-Fi Bridge is optional but highly recommended. Without it, you can still unlock via Bluetooth when nearby. The Wi-Fi Bridge enables remote access, real-time notifications, access logs, and the ability to grant temporary access to guests from anywhere.
