Cloning a BMW G/U Chassis BDC3 key is a common task for professional locksmiths and advanced automotive technicians. With the Xhorse VVDI Key Tool Plus, the process is straightforward, efficient, and reliable. This guide walks you through the complete procedure, and the same method is also applicable to Key Tool MIDI and VVDI2.
Step 1: Read Vehicle Information
The first step is to retrieve the vehicle’s immobilizer data from the BDC3 system.
① Enter the Immo Programming menu on the VVDI Key Tool Plus and select the BMW brand.
② Choose G/U Chassis BDC03 / BCP IMMO System from the list.
③ Click Start Programming to begin the process.
④ Select Read Vehicle Information to read and save the BDC3 data from the vehicle.
This step ensures the tool correctly identifies the vehicle configuration and prepares the system for key data processing.
Step 2: Read the Original Car Key
Next, you need to extract data from the original working key.
① Select Read Original Car Information on the device.
② Solder four wires from the MCU cable to the designated contact points on the original BMW key.
③ Connect the MCU cable securely to the VVDI Key Tool Plus.
④ Click Read to extract and store the original key data.
This step is critical, as accurate reading of the original key ensures a successful clone without errors.
Step 3: Make the Dealer (Cloned) Key
With both vehicle and original key data successfully read, you can now generate the cloned key.
① Re-enter Read Original Car Information.
② Select your preferred key generation method according to your working needs.
The VVDI Key Tool Plus will then generate a cloned BDC3 dealer key, ready to be used on the vehicle.
Cloning a BMW G/U Chassis BDC3 key using the Xhorse VVDI Key Tool Plus Pad is a well-structured and user-friendly process. By following these three main steps—reading vehicle information, extracting original key data, and generating the dealer key—you can complete the job efficiently and professionally.
