KEYDIY KD-MAX key tool plus offers a streamlined solution for adding FGB keys to BMW BDC3 systems. Using the dedicated BDC3 dismantling-free clip and programming cable, this process eliminates the need for complex disassembly or soldering. Here’s how to operate efficiently and safely.
Tools Required:
KD-MAX Diagnostic Tool
BDC3 Specific Dismantling-Free Clip
Cable Series Cable (for BDC3 Clip 2K DMAX)
FGB57 Smart Key
Step 1: Prepare the Hardware
Begin by unpacking the BDC3 dismantling-free clip and ensuring all four switches are turned on. The clip features four clearly labeled wire ports—orange, black, red, and brown—which must be connected sequentially to the corresponding programming cable. Secure the connections firmly to avoid communication errors during the process.
Step 2: Connect the Key and Tool
Remove the back cover of the original BMW key and attach the BDC3 clip securely to the key’s circuit board. Insert the programming cable into KD-MAX key tool plus, ensuring a stable connection. Proper contact between the clip and key is critical for successful data reading and writing.
Step 3: Navigate the Software
Power on the KD-MAX and access the “Remote Function” menu. Select “Smart Key Clone,” then choose “BMW BDC3 BCP Smart Key Clone.” Proceed to “G Chassis BDC3 XO In” and confirm the selection. Click “Read Chip Data” to extract information from the original key. Follow on-screen prompts to save the data.
Step 4: Program the FGB Key
Place the blank FGB57 key in the KD-MAX induction area. Select “KDFGB Type” and “KDFGB Remote” from the menu. The tool will automatically write the saved data to the new key. Once completed, the key’s PCB can be installed into its case and tested in the vehicle.
Ensure all software and hardware are up to date for optimal performance. Always test newly programmed keys in the vehicle to verify functionality.
