51DK is a connected-car digital key management tool designed to work with our company's corresponding in-vehicle smart hardware devices. Say goodbye to traditional physical keys — your phone is now your car key, giving you full control of your vehicle anytime, anywhere, for a safe and convenient smart driving experience. Core Features: Lock / Unlock via the App Lock and unlock your car doors with a single tap on your phone. Once unlocked, you can start the vehicle — no physical key needed. Bluetooth Comfort Access Your vehicle unlocks automatically as you approach with your phone, and locks automatically as you walk away. You can also set the vehicle to turn off automatically when locking. Vehicle Location & Tracking Check your car's location in real time and replay historical driving routes. Find your car instantly in large parking lots with one-tap locating, flashing lights, and horn honking. Key Authorization & Sharing Generate temporary digital keys and share driving access with family or friends. Set validity periods and revoke access anytime. Multi-Vehicle Management Bind multiple vehicles to a single app, switch between them quickly, and manage all your digital keys and vehicle status in one place. Security Monitoring The network version terminal supports anti-theft mode. When armed, it monitors the vehicle status in real time and pushes instant alerts to you if a theft alarm is triggered.
