This guide provides a step-by-step workflow using Xhorse MULTI-PROG for data reading, and Xhorse VVDI2 or Key Tool MIDI for dealer key generation. This method ensures high compatibility with VVDI smart keys and reliable vehicle synchronization.

Step 1: Read IMMO Data with MULTI-PROG

The first step involves extracting the vehicle’s security data to create a valid key file.

• Tool Required: Use Xhorse MULTI-PROG to access the EEPROM/IMMO data.
• Connection: The hardware supports both soldering and solder-free adapter methods.
• File Management: Save the read IMMO data file carefully; it is essential for the following steps.

Step 2: Generate VVDI Smart Key

Before finalizing the dealer key, you must prepare the VVDI remote hardware for the MQB49 system.

Method A: Using VVDI2

1. Connect VVDI2 to your PC, navigate to Transponder Programmer > Prepare Remote/Proximity Key > Prepare proximity remote > Europe > VW > MQB49/5C(New)
2. Place the VVDI key into the programmer coil.
3. Click Generate to prepare the smart key.

Method B: Using Key Tool MIDI

1. Enter Remote Program > VW > MQB49/5C(New).
2. Place the VVDI key into the induction coil and click Generate.
3. 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.

• Use either VVDI2, Key Tool MIDI or Key Tool Plus to perform the final key learning on the vehicle.
• This step synchronizes the new dealer key with the vehicle’s immobilizer system.

How to Modify Key ID by KEYDIY KD-X4 and FGB25 FGB08 Keys?

 This post explains how to modify original key ID using KEYDIY KD-X4 with FGB25/ FGB08 key.

Preparation:

KEYDIY FGB25–5 Smart Remote

KEYDIY FGB08 PCB Key Board

KEYDIY Clamp Adapter Set

KEYDIY KD-X4 5-in-1 key programmer

Mobile phone

First Thing — Check Your Key

When you get this KD FGB25–5 key, a few things might happen:

• The chip could be 5C or a 46 chip
• Sometimes there’s no frequency when you put the battery in
• No frequency? Just generate it — it’ll come back to normal ✅

Why Bother Modifying the ID?

This is mainly for official after‑sales service and repairs. The system reads the key ID that’s stored in Volkswagen’s official server. Matching that ID avoids trouble down the road.

Let’s Do It — Step by Step

1. Get into the matching function

• Connect your KEYDIY KD-X4 key programmer
• Select IMMO Programming-> IMMO Programming-> Volkswagen-> Select by type-> 5C/5D Immobilizer system-> Start Execution

• We’ll use two types of 5C keys: a flip key and a B8 key

1. Insert the adapter

Plug the adapted version into the device and hit "Start" to read.

1. Choose how to get the ID

You’ve got two choices:

• Press [Yes] to start reading and the proceed with the disassembly and generation.
• Press [No] to directly disassemble and generate

1. Connect the cable

Grab the cable with the two pins (they’re identical). Stick them into either pin position, then insert the pin onto pin one. Hit Start Reading.

1. See the service code & ID

The system shows you a service code and the ID it just read from your key.

Example time!

Let’s say the ID is 63,366,333. We want to change it to 12345678.

• Enter 12345678 and write it to the original factory key

• Select "Original Key (Non-Vehicle)"

• Cost: 100K coins or $2 per modification (coins used first, then money — no double charge for the same key)

Click OK — write successful!

1. Check it worked

Identify the key again. The new ID should be 12345678. Boom — modified!

Now About KEYDIY 5D Key

KEYDIY 5D key works with:

• FGB23, FGB57, FGB58

Besides doing everything those three BMW keys do, the 5D key also works as a ZB (emergency key) and supports the 5D function. But heads up — you need to buy both key types (KD FGB25–5 and KD FGB08) to use the 5D function.

BMW covered:

• CAS4, CAS4+
• FEM, BDC, BDC2, BDC3, BCP

Audi 5D Key

Same card plate as before — just plug it in and read. Super simple.

How to Program 5D Key

1.Go back and restart the process. Click OK.

2.Choose ID option:

• Keep ID = random ID
• Enter ID = type your own

3.Place the key in position, pick Keep ID (or Enter ID if you need a specific one).

4.Select KDFGB (wireless), choose your frequency, and generate.

5.Check it — should now show as 5D with a random ID.

6.Use the key learning function to pair it with the car.

All done!

KEYDIY FGB25, FGB08, and 5D keys give you tons of flexibility for VW and BMW work.
