Step-by-Step Procedure to Add VW 5C/5D Keys
Now that we have the basic requirements covered, let’s dive into the procedure for adding the VW 5C and 5D keys:
1. Navigation Path
Follow these steps:
- Select IMMO Programming
- Choose VW
- Pick Select by Type
- Choose MQB Instrument
- Select Dismantle and Read Key to obtain data
- Choose MQB49 (5C) Key Disassembly Reading or MQB49 (5D) Key Dismantling and Reading
2. Making Connections
When dealing with the hardware, there are critical warnings that need to be addressed:
-
Critical Hardware Warning: This procedure requires attaching cables to the circuit board of the key. Be aware that cable colors can sometimes be misleading.
- Two versions of the cable exist: MCU V1.0 and MCU V1.1. In the V1.1 cable set, one wire labeled "RED" appears purple in color. Using this wire based solely on its label may cause permanent damage to the key.
- Soldering the Connection: The clock cables are exceptionally short and should not be extended. They need to be accurately soldered to designated processor pins (for example, pin 24), as per the illustration provided in the software diagram. Precision is vital to avoid short circuits.
3. Reading Original Key Data
Two main options will be available for reading key data:
- Keyless Go
- Non-Smart Key
Choosing the correct option depends on the key type you are working with. The essential step is selecting the Disassemble and Read Key Data option. After reading, ensure to save the key data file.
4. Generate Dealer Key
Utilize the saved key file to generate a new key.
5. Learn Key in Car
Finally, perform in-car key learning. Be mindful that:
- Some models from 2023 onward may require SFD Gateway unlocking before key learning can proceed in the vehicle.
Key Considerations for MQB 5D Keys
The procedure for newer 5D system keys, frequently seen from 2023 and later, follows a similar protocol. The key design may differ, but the wiring precautions remain critical: always use the appropriate purple wire from the V1.1 cable set and never rely on the mislabeled “red” wire.
