Xhorse Multi Prog BMW CAS4 Adapter Chip Crack Failed

 Problem:

Read BMW CAS4 module with Xhorse Multi Prog and XDNP12 CAS4 solder free adapter.

Pins flown in/cleaned, in the pin test passes ok, Procka Mask selected correctly, external power power plugged in – processor detects as unknown and does not want to secure.

Error chip crack failed.

Any advice?

Solution:

Double check connection, if pin test passes ok,  when using solder free adapter, try to lower VPP voltage to 3.3V and VCC to 5V. 

You have to manually change the values of vcc and vdd.

Or read directly without an adapter.

VVDI Key Tool Plus Add 2019 Porsche Cayenne MLB Key

 User review:

“Porsche 2019 Cayenne MLB add key success using Xhorse VVDI MLB Tool + VVDI Key Tool Plus.

Solder to the chip directly. Capacitors removed and reinstalled (a pain). Better to order new capacitors (0.1uF, 0603 package capacitor) in case they get lost or damaged. Had to put them back if it is a Cayenne.

Did a Lamborghini Urus prior and broke the shell but had replacement aftermarket. At the time I would of rather broke the shell than risked damaging the chip. Had a new replacement Porsche shell on standby but I managed to cut away super clean and reuse original shell. After you generate the dealer key you have to learn 2 keys next as it wont let you learn the newly added key alone. Learning sensor is on cupholder closest to driver for reference.”

Xhorse Generate Hyundai 47 Chip using VVDI Super Chip

Question:

Will Xhorse generate Hyundai 47 blade chip using VVDI Super Chip XT27A. Tried all of them didn’t work.

Here is the clue.

Xhorse XT57B definitely will do but it is not available yet. The XT27A also works.
Here is the tip to generate Hyundai 47 with XT27A.

Try with New 7938 -xt27. It’s working.

Generate ID47, then tap “New 7938 chip” and then “Generate”. Not ID47 Hyundai.

Xhorse Key Tool Plus BCM2 Adapter V2 Failed to Write Dflash Pflash Error

Problem:

Tried to add key 2014 Audi A4 BCM2 using Xhorse vvdi key tool plus and new Audi BCM2 solderless adapter. I read the BCM Lock 1 & 2 data, and I have the IMMO data. While writing back the data, a connection failed, and now, of course, the car won’t start. How can I write the data back?

Solution:
You must write back service file. If you have data1 and data2, calculate service file and write it back. Car will start again.

Here is the option to write service file.

Program Ford KA 2014 Smart Key by Xhorse Key Tool MIDI

 In this guide, we’ll walk through programming a spare remote key for a Ford KA 2014 using the Xhorse VVDI Key Tool MIDI. This model uses a Fiat-based immobilizer system, similar to the Fiat 500 (2008–2017).

Tools and Parts Needed:

VVDI Key Tool MIDI

A new Ford KA Key

Original Working Key

Step-by-Step Programming Guide

1. Connect to the Vehicle

Locate the OBD port behind the dashboard panel, connectKey Tool MIDI toOBD.

2. Access the Correct System

Since the Ford KA 2014 uses a Fiat-based system, but the Key Tool MIDI doesn’t list it in menu now(Update will be coming soon).

• Go to: IMMO Programming → EUROPE → FIAT → Select by Area → Fiat 500 Flip key(2008–2017) → IMMO system(DELPHI 70F3632/70F3633_ID46) → Start programming

• Two system options may appear. Start with Type 1.

3. Read PIN and Key Data

• Select “Display Immobilizer Information(PIN, Key ID)” to read the PIN code and key data from the BSI (Body Security Interface).

• The tool will display the PIN (e.g., 34385) and current key count.

4. Generate Dealer Key

• Choose “Make Dealer Key”.
• Place the new keyinto the Key Tool MIDI programming coil.
• The tool will generate the dealer key successfully.

5. Program All Keys

• Go to “Key Programming”.
• The PIN code should auto-fill. Confirm and proceed.
• Follow the on-screen instructions to program each key one by one.

Important: Always program original keys first to avoid locking them out.

• Insert each key, turn the ignition ON, and confirm programming.Repeat for all keys (original and new).

After programming, the tool should show the updated key count (e.g., 3 keys).

Test each key to ensure it starts the vehicle.

Sync Remote Central Locking Tips

If the remote doesn’t work initially:

• Disconnect the OBD cable, either reset the BSI or disconnect the battery.
• Insert the key, turn ignition ON, and repeatedly press the remote button. Activate central locking multiple times to sync.
• If issues persist, try the “Remote Renew” or “Unlock Key” function, or repeat the process using the other BSI type in the tool.

Final Checks

Verify all keys start the vehicle, test remote locking and unlocking.

Ensure no warning lights remain on the dashboard.

With the Xhorse VVDI Key Programmer, programming a spare key for the Ford KA 2014 is quick and reliable. Always remember to reprogram all existing keys to maintain system access.
