- Click Generate to prepare the smart key.
Method B: Using Key Tool MIDI
- Enter Remote Program > VW > MQB49/5C(New).
- Place the VVDI key into the induction coil and click Generate.
- Wait for the writing process to complete.
Step 3: Generate VW 5C/5D Dealer Key
Now, load the previously saved IMMO data to authorize the key as a “Dealer Key”.
- Using VVDI2: Navigate to VW > Key Learn > MQB platform instrument immobilizer > instrument with 5C/5D immo(MQB49, HitagPro, 2019.10-) > Make Dealer Key > VW > Make MQB49/5C remote key with “VVDI proximity remote”.
- Using Key Tool MIDI: Go to IMMO Programming > VW > Select by Type > MQB instrument immo system > Instrument MQB49/5C system > Start programming > Method 1 for Adding Keys – Reading Key Data > Keyless Go > Generate Dealer Key – Load Key File > VVDI Key.
- Final Action: Load your IMMO file, ensure the key is in the coil, and click Generate.
Step 4: Key Learning on Vehicle
After the “Dealer key generated successfully” message appears, the key is ready for programming.
