M365 Lock is a free Android application developed by Jarek Apps, designed to improve the safety of Xiaomi M365 or M365 Pro electric scooters. With voice control, the application can lock, unlock, or turn off the e-scooter. It also features a dashboard with real-time information on speed, battery level, distance traveled, and controller temperature. The app has a night/day mode, metric or imperial units of measure, lock, unlock, turn off and disconnect buttons, a voice control button, and a horn button. However, it only works on e-scooters with custom firmware or downgraded firmware. The software locks the scooter, making it difficult to move without heavy resistance and annoying beeping. The anti-theft app for Xiaomi M365 with voice commands is an effective preventive measure for deterring thieves. The M365 Lock app is available for free, but use of the application for M365Pro and M365 is at your own risk.
