BMW CAS3+ all keys lost programming has been done with Yanhua Mini ACDP and module 1 by ISN mode.
Main steps:
Step 1: Read ISN
Step 2: Read CAS data
Step 3: Program a new key
The procedures:
DME module: CAS3 MSV80
According to the picture tip to find the DME module in the car and remove it
Step 1: Read ISN
1.All devices required:
ACDP host, PCAN cable, OBP+ ICP adapter
2.Connection:
Short the CAN termination resistor on the OBP+ICP adapter to the “CAN-R-Join” terminal
Connect OBP+ ICP and PCAN cable

Record ISN manually or click “EXPORT” to export directly
Save the ISN data
Step 2: Read CAS data
1.Connection:
Open the CAS3 module
Prepare all devices: CAS3 interface board, 20 pin cable, OBP+ ICP adapter, BDM01, ACDP host, Blank key and BAV-Key adapter
Install the copper pillar
Find the location hole D1- D4

Click “Step 2: Generate Dealer Keys”>> All-Key-lost (ISN mode)
Connect the ACDP Mini and BAV adapter according to the diagram and insert a blank key
Read out the key info and status
Select the corresponding CAS data file
Check the VIN of the selected data
Select any blank key number and then select option based on the key type
Confirm the key is put in the adapter
Manually enter the ISN or click “Import” to import directly
Then confirm the ISN
Save the CAS data which contains the info of programmed key and new key
Load the DME module and CAS module and learn the new key
Finally, use the new key to start the car
Done!
