APP2 (AP Pro2) joins AUTEL and AVDI with its new BMW BDC2 software upgrade (Add key only).
It is the simplest and lowest-risk device to do BMW BDC2 in the world at present.
No need to find reset point on BDC2 module, no manual job.
Fully automatic operation, it will back up coding. Job could be done in minutes.
NOTE: Requires AP special key. Only APPRO-specific new keys are supported.
Future updates will support BDC2 all keys lost matching and other advanced features.
Here we will show how to add BMW BDC2 key with the APP2 tool.
Require Function Authorization: [FN0050] – BMW BDC02 (G-Serial) IMMO Matching. The Full version already has BDC2 license activated. No need license for per VIN as Autel BDC2.

The BDC02 IMMO matching process is simple and safe, taking only 4-5 minutes. The whole process is simple than FEM/BDC:
- 1. Platform wiring
- 2. Preprocessing (retrieve key data)
- 3. Generate a new key.
1. Preparations
Required Equipment and Adapters
APPRO2 Host, USB cable, 12V AC/DC power supply (self-purchased).
A17-BDC02 Adapter (provided free with FN0050 module).
Ensure the software is updated to the latest version.
Vehicle Identification via BMW Self-Diagnosis
Use BMW OBD Auto Recognition [0049] to identify the vehicle model.
BMW OBD Auto Recognition Interface
Open the application interface: Vehicle Model > BMW > BDC02 (G-Serial) [0050].
BMW>BDC02(G-Serial)[0050])
Check for error messages. If none, proceed.
2. Vehicle BDC02 Module
Pre-Service Inspection
Verify the vehicle is functioning normally and document its condition.

Signal Descriptions:
Power (Red Wire): +12V power output controlled by the host (ensure the host is connected to a 12V power supply ≥3A).
GND (Black Wire): Ground connection (CON7-4).See wiring diagram for GND (black wire).
RESET (White Wire): Connect to the 5th gold finger on the BDC board edge (counted inward from the edge).See the marked white line.
25LC256-PIN2 (Brown Wire): Boot signal connected to PIN2 of 25LC256 (SO-8).

3. Data Reading and Preprocessing Steps
3.1 Back Up Coding Data with APP2
3.2 Preprocess the Module (3-4 Minutes)
Preprocessing Module, ensure stable internet connection to APPRO servers during preprocessing.
Pre-processing module process. Do not disconnect the 12V host power warning prompt, the power supply of BDC02 is controlled by the device host output.
Preprocessing in progress
Preprocessing finished. Save coding data.
Preprocessing completed (Key Password Data Retrieved). Now you can generate dealer key with the data.
4. Programming a New Key
Load the retrieved key password data to generate a new key.
Load the key password data, select a Blank Key Slot (Key ID: FFFFFFFF) to generate a new key.
