How to Add BMW BDC2 and BDC3 Keys Using Autel IM508/IM608 and APB113 Adapter

If you're in the automotive diagnostics field and looking to expand your skills in key programming for BMW vehicles, you've come to the right place. This comprehensive guide will walk you through the process of adding BDC2 and BDC3 keys using the Autel IM508 and IM608 key programmers along with the APB113 adapter. This function is essential for technicians who work with modern BMW models, specifically from years 2017 to 2020 for BDC2 and from mid-2020 onwards for BDC3.

Requirements for Key Programming

Before diving into the process, ensure you have the following tools:

• Autel IM608 or IM508 key programmer
• Autel XP400 or XP400 Pro programmer
• Original working key
• Autel BMW key (e.g., IKEYBW003A for 3-button or IKEYBW004AL for 4-button)
• APB113 Adapter

Note that the key programming function we will discuss is specifically designed for generating Autel BMW keys.

Adding a BMW BDC2 Key

To add a BDC2 key, follow the navigational path outlined below:

• Manual Selection > 2017 to 2020 G38 > Control Unit > BDC02 Immobilizer > Key Cloning

The process consists of three main steps:

Step 1: Read Vehicle Information

Begin by reading the vehicle’s VIN and selecting the appropriate key frequency.

Step 2: Read Key Data

1. Connect the device to the IM508 main unit.
2. Insert the working original key into the XP400 programmer’s key slot.
3. Consult the key wiring diagram to ensure proper connection.
4. Using the Autel APB113 adapter, connect the key’s circuit board to the XP400 programmer.
5. Once the connection is made, successfully read the key data.

Step 3: Generate Dealer Key

1. Place a new, blank Autel BMW key into the programmer’s slot.
2. Initiate the key generation process (this typically takes 1-3 minutes).
3. Once completed, you’ll receive a confirmation of successful key programming.

Adding a BMW BDC3 Key

The process for adding BDC3 keys is quite similar to that of BDC2. Here’s how to go about it:

• Manual Selection > 2020/07 G30/G31/G60 > Control Unit > BDC03 Immobilizer > Key Operation > Add Key

Choose the correct key type, either Unencrypted or Encrypted + Unencrypted.

To clone an encrypted BDC3 key, follow these steps:

Step 1: Read Vehicle Information

Similar to the BDC2 process, read the vehicle’s VIN and select the appropriate key frequency.

Step 2: Read Key Data

1. Connect the XP400 or XP400 Pro to the IM608 or IM508 main unit.
2. Insert the working original key into the XP400 programmer’s slot.
3. Refer to the key wiring diagram for the necessary connections.
4. Solder the Autel APB113 adapter cable to the key circuit board and connect it to the XP400 Pro Programmer.
5. Successfully read the key data.

Step 3: Generate Dealer Key

1. Place a new, blank Autel BMW i key into the XP400 Pro programmer’s slot.
2. Initiate the key generation process (again, this typically takes 1-3 minutes).
3. You will receive a confirmation of successful key programming once the operation is complete.

Conclusion

By following these steps for both BDC2 and BDC3 keys, you can effectively expand your capabilities in automotive key programming using the Autel IM508 and IM608 devices. Mastering this technique not only enhances your technical skill set but also improves service offerings for BMW clients.
