Prerequisites

Before using an Autel scan tool for key programming, make sure you have the following tools and materials available:

1. Autel IM508S or IM608S II scan tool, as both models have a powerful key programming feature.
BMW keys (new or blank), which can be purchased through your car dealer or locksmith.
2. The vehicle's VIN (Vehicle Identification Number) and proof of ownership (e.g., vehicle registration document or driver's license), as these documents are required to verify ownership before programming the key.

Steps to Generate a BMW Key Using Autel Scanner

Step 1: Connecting the Scan Tool

Connect to OBD-II Port: Plug the Autel Scan Tool into the vehicle's OBD-II diagnostic port, which is typically located under the driver's side dashboard.
Turn on the Vehicle Ignition: Ensure that the vehicle's ignition is in the “on” position. The engine does not need to be running.

Step 2: Launch the Autel Scan Tool
Launch the Autel Scan Tool and navigate to the main menu.
Select the “Key Programming” or “IMMO (Immobilizer)” option, which will lead you to the Key Programming screen.
On the screen, select BMW as the make of the car and then select the specific model and year of the car.

Step 3: Read and Verify VIN
Read VIN: The scan tool will automatically read the VIN of the BMW to verify that the VIN matches the actual vehicle information. If the VIN does not match, programming cannot continue.
Verify Ownership: To prevent unauthorized duplication of the key, the system may ask for proof of ownership, such as the vehicle registration or owner identification.

Step 4: Programming a New Key
Insert New Key: Insert the blank key into the ignition as instructed on the scan tool. the Autel scan tool will begin communicating with the vehicle's ECU (Electronic Control Unit).
Synchronize the key with the ECU: The scan tool will communicate with the BMW's ECU via the OBD-II interface and send programming commands to the vehicle's immobilizer system (e.g. CAS system). This process will program the key chip so that the vehicle immobilizer system will recognize the key.
Completing the Programming: Once the programming is complete, the scan tool will notify you that the program has been successfully completed. At this point, the new key should be able to start the vehicle and operate the door locks.

Step 5: Test the new key

Once the programming is complete, it is important to test the new key:
1. Make sure the key starts the vehicle properly.
2. Check that the key unlocks and locks the doors, including any remote unlock functions.
If everything works, you have successfully programmed your BMW key. If you need to program another key, you can repeat the same steps.

Important Notes

BMW CAS Systems: Some BMW models utilize the more complex CAS (Automotive Access Control) anti-theft module and may require additional steps or tools.The Autel scanning tool is generally supported by most BMW models, but for some models you may need additional adapters or programming cables.
