How to copy and clone BMW U Chassis BCP key data using the Autel IM608 together with the GODIAG BCP Adapter. Follow the complete step-by-step process for reading BCP key data and performing key programming on supported BMW U Chassis vehicles.
The process is straightforward but requires meticulous attention to the tool’s prompts and the physical connections.
Model example: 2024 BMW I7 BCP system

Preparing the Vehicle and Tool
Before diving into the software, connect the BCP adapter with XP400 pro. With the Godiag BCP clip adapter, you don’t need to disassemble the inner key shell. Just dril a hole to the inner key shell and connect the clip with inner key shell according to the points.
Step-by-Step Cloning Process
Accessing the BDC Function: On the Autel IM608, Selects the “BMW”, then chooses “System Selection” to allow the tool to automatically identify the vehicle’s system. Then navigates to “Immobilizer” – “BCP Immobilizer” – Key Operation – Add key. Select Encrypted or Unencrypted key type.
Identifying the Vehicle: The tool prompts you to enter the vehicle’s VIN (Vehicle Identification Number). Confirms the VIN and selects the appropriate frequency—in this case, 433 MHz, a common frequency for BMW remote keys.
Choosing the Key Type: A crucial decision point appears: must choose between an “OEM key” (likely referring to a master/original key) or a “Autel Key.” In this instance, we chooses the “Autel Key” because he only has a single Autel key available to clone. It is important to note that a Autel key is often a valet or limited-access key. Cloning this type replicates its specific permissions and restrictions.
Generating the Dealer Key: The tool displays a warning: “This function can only generate the Autel key.” After confirming, places the new, blank key into the designated programming slot on the IM608 (or the connected key programmer). Then presses “OK,” and the tool begins generating the key data.
Successful Generation: Within moments, the IM608 displays “Success.” The tool asks if more keys are needed; declines and proceeds.
Verifying the Clone
With the programming complete, the true test is functionality. Takes the newly cloned key and performs a series of checks:
Door Lock/Unlock: open and close the door to test the remote’s locking and unlocking functions. The vehicle responds correctly.
Ignition/Start: Finally, he places the key in the vehicle and starts the engine. The car starts without hesitation, confirming that the clone process was a complete success.
Key Takeaways and Best Practices
Autel vs. Master Keys: Understand the difference between key types. Cloning a Autel key will produce a copy with the same limited access. If you need a master key with full access, you must clone from a master key.
Follow Prompts Exactly: The Autel IM608 provides clear, step-by-step instructions. Rushing or skipping steps—especially regarding physical connections and key placement—can lead to failures.
Verify Before Finishing: Always test all functions (remote locking/unlocking and engine start) before handing the key to the customer.
Conclusion
Cloning keys for newer BMW models is no longer a simple cut-and-program job; it requires advanced diagnostic tools, specific adapters, and a clear understanding of the vehicle’s security architecture. The Autel IM608, combined with the BDC3 adapter, provides a reliable and efficient solution for locksmiths facing these modern challenges.
