The control code is the vehicle identification number (VIN) of the car. The VIN, also known as the vehicle identification code, consists of 17 digits and letters. You can find the VIN on the left side of the car's dashboard or under the front windshield. It is also available on the vehicle's registration certificate and policy.

I recently used Changan's car control code, which is essentially a digital key feature. When lending the car to others, there's no need to hand over a physical key. Instead, you can generate a six-digit password in the mobile app and share it. The recipient can then input this code to unlock the car door or even start the engine. This is especially convenient for temporary situations like friends borrowing the car or valet parking, eliminating the need to exchange keys in person. However, remember to set usage limits—typically allowing only one or two starts—to ensure . This feature is now available in the latest Changan CS75 PLUS and UNIT-V models, making it possible to handle everything with just a smartphone when heading out.

From a technical perspective, this vehicle control code is essentially a cloud-verified temporary authorization mechanism. When you generate a dynamic code in Changan's vehicle control app, the system sends an instruction to the car's head unit to activate the pairing function. Others within the vehicle's signal range can then open their phone's and complete identity verification by entering the password you provided, effectively replacing traditional key fob chips. The entire process takes just three minutes, but it's important to ensure stable network connectivity to avoid recognition failures. Many brands are now adopting similar technologies, and Changan's user interface is particularly intuitive.

I think this feature has a good safety factor. The control code can be set with a maximum of 10 usage limits, and it will automatically become invalid if exceeded. The system sends a notification in the APP after each use. Last time I lent the car to a relative, I could see the usage records in real time. Compared to handing over the keys directly, the risk of password leakage is much smaller. However, it's still recommended to use it in conjunction with the vehicle positioning function, so that in case of any issues, the car can be locked immediately via the cloud. Car theft isn't very common nowadays, but we shouldn't relax our anti-theft awareness.

This feature has saved me a lot of trouble in real-world car usage. Last time I parked at the airport for a business trip, my family just used a remote control code to pick up the car. Also, when leaving the car at a car wash, there's no need to hand over the key, eliminating the risk of losing it. Even during sudden business trips, I can confidently let colleagues move the car—just enter the password and drive away. It's recommended to pair this with door sensor distance settings, keeping the authorization range within 5 meters for added . Now, the smartphone has become a universal car key.

It's actually very simple to operate: Open the inCall app, go to the vehicle control page, click to generate a control code, set the usage time and frequency, then share the password with the other party. The other party needs to turn on their phone's Bluetooth, enter the password in the Changan APP, and click to match. The car lights will flash twice to indicate successful authorization. The whole process takes just two minutes, no need to even check the manual. However, it's important to note that the vehicle's battery must remain powered; if the car has been parked for a long time and the battery is dead, this feature won't work. Compared to traditional car borrowing methods, this saves at least half an hour of hassle.
