Free BMW BDC02 BDC03 Add Key with Autel IM

BMW cars have always been known for their high-end features and safety standards. As a BMW owner, are you still annoyed that your BMW's high-safety BDC module cannot quickly add keys? Do you feel that even if you buy an expensive key programmer, you still have to pay extra to add keys to your BDC2 and BDC3 module vehicles, which you think is not worth it?

At the start of 2026, Autel officially announced some good news: you will no longer be bothered by the aforementioned issues or troubled by the need to disassemble and read the BCD module. To better serve Autel fans, the Autel key programmer now supports adding keys to BMW BDC02/BDC03 models free of charge.

So how do you use this feature? Which Autel key programming tools are needed? Which BMW models does it primarily support? In what ways is this feature more convenient than before? Let's take a look!

What are BMW BDC02 / BDC03?

BDC stands for Body Domain Controller. This control module is commonly found in new BMW models and is primarily responsible for the key/anti-theft system, central locking, lighting, and communication with vehicle-related ECUs. BMW BDC02 and BDC03 are BMW's second and third generation BDC modules, respectively.

These two BMW BDC modules have high security levels, stronger encryption, and more stringent key data reading requirements, necessitating the latest software and server authorization. Therefore, adding a key to a BMW equipped with these two BDC modules is always very difficult.

Add Key Operation Process

Step 1: Update and upgrade the Autel key programming tool

Although Autel officially states that it now supports the addition of a key function for special BDC modules for free, existing Autel IM508S Pro/IM608S II tablet owners still need to upgrade their devices to the latest version to ensure that they can support this function. This is the first step before proceeding with any further operations.

Step 2: Remove the original key chip

Adding a key to a BMW BDC02/BDC03 requires soldering the original key chip onto an APB113 circuit board to connect it to the XP400 Pro key programmer for further operations. Therefore, the second step is to remove the original key chip and solder it onto the APB113 circuit board.

Note: This adapter is not currently sold separately. If needed, you can purchase the Autel IMKPA Adapter Kit, which includes various adapters to suit different vehicles.

Alternatively, if you do not currently have Autel key programming tools, you can purchase the Autel IM608S II Full Kit, which includes a complete set of key programming tools for IMKPA, APB112, and GBOX3; however, this kit is more expensive.

Step 3: Correctly connect the scanner, XP400Pro, and car

Connect the scanner to the vehicle via the car's OBD port to establish communication. Simultaneously connect the XP400 Pro to the scanner, ensuring proper communication and connection between the three.

Step 4: Find the specific path to the option to add a key

Operating Path:

MaxiIM > IMMO > Select the Corresponding car model (Auto selection/Manual selection) > Control Unit > BDC03 Immobilizer > Key Operation > Add Key > Encrypted and unencrypted

The above path is for reference only. Different Autel key programming tools and different BMW models may result in different operating procedures. After finding the "Add Key" option according to the above path, confirm that the vehicle is in good condition and the key programmer XP400 Pro is connected, you can begin the key addition process.

Step 5: Start Adding BMW keys

Follow the instructions for the Autel IM series scanner.

1. First, read the vehicle information, enter the 17-digit VIN code of the car, and determine the frequency of the smart key.

2. Place the original, working key chip in the XP400 Pro's sensor area to read the original key's information.

3. Follow the instructions to connect the soldered key plate to the APB113 board, and install the APB113 board on the XP400 Pro.

4. To generate a dealer key, place a blank key in the sensor slot and wait 1-3 minutes for the key to be successfully added.

Step 6: Testing the new key

After generating the new key, test its functionality to ensure it works properly, including locking and unlocking the doors, raising and lowering the windows, and starting the vehicle. Also, avoid storing the old and new keys together to prevent signal interference.
