What is the difference between generate new key and duplicate key in Yanhua Mini ACDP MQB RH850 Module 34?
First change the ID of the new key to the lost ID of the original car key, and then learn it, which is like copying the key. In this way, there will be no problem in entering the 4S store for online programming. If you add a key and when enter the 4S store for programming, the server will query the key. Leaving the keys may be illegal and will lock the vehicle,so normally,we suggest duplicate a key!
