Keydiy KD-X6: Read MQB48 Key Data Directly – No External Device Needed

A significant upgrade of the Keydiy KD-X6 key programming tablet is the integration of MQB48 and MLB functions. Our customers have tested the built-in features and provided us with positive feedback, and we are pleased to share this with you.

 

Model example: 2019 Audi Q3

Transponder: MQB / ID48 chip

 

Disassemble original MQB48 key.

Turn on KD-X6 tablet.

Go to IMMO Programming- MLB/MQB48 function- MQB48.

Check key wiring diagrams and find the correct one that matches your original key circuit board.

Follow diagram to solder wires to the key circuit board. Need to remove a capacitor carefully.

Then read MQB48 key data.

Calculate key data in 5 minutes; not very fast, but very stable.

Restore the capacitor on the key circuit board after the data reading is finished.

Then generate dealer key and learn key following the KD-X6 prompts. The key learning procesure is the same as KD-X4.
