The second option (Select according to CPU model).








Read the note.


Automatic pin detection.

If the detection fails, please check and clean up the test points.




Decrypting chip, please wait..




Check the VIN number.



Automatically upload and backup data.




The CAS4 PCB is processed


Automatic enter the "Add key" function.



Connect BAV-key adapter and put it into the blank key.


Please check the blank key ID.



Please select the CAS data you want.


Check the VIN number.



Choose any blank key number.



Take out the blank key and put in the working key.



Reading ISN code.


Check ISN code and VIN number.



Put in the blank key again.

Yanhua Mini ACDP On BMW Mini Cooper key programming: 100% Work!

Confirmed: BMW Mini Cooper remote programming can be done by Yanhua Mini ACDP programmer.

If it is CAS3, ACDP can do via OBD, if it is CAS3+, ACDP can do only after dismantling the CAS3+ and program new key using interface board.


Method 1: ACDP program remote on Mini Cooper using the interface board


Method 2: ACDP program remote on Mini Cooper via OBD

Obd port: located in the driver side, on the left


Connection: Mini ACDP is connected to the car, through OBD

The test:

Insert the key

Run Mini ACDP application on the mobile

Run BMW module programming


Select CAS3/CAS3+


OBD mode

Yanhua ACDP CAS3 add key-6


Yanhua ACDP CAS3 add key-7

Step 1: read CAS data

Step 2: generate a dealer key/program a key

Step 3: write new key data into CAS

Step 1: read CAS data

ACDP is gonna to read CAS data

Yanhua ACDP CAS3 add key-8

Pop-up: Take out the key and wait for 5 min.

If the key without ignition-start function, take the key outside the car, 3m away

Read immo data successfully

Yanhua ACDP CAS3 add key-9

File (CAS3_ORGKEYxxxx.bin) has been backup.

Yanhua ACDP CAS3 add key-10

Upload bin file

Save the immo data to generate a dealer key

Yanhua ACDP CAS3 add key-11


Step 2: generate a dealer key/program a key

Yanhua ACDP is gonna to add a new key

Check the connection of BAV adapter

Prepare a blank key

Choose the correct bin file with immo data

Yanhua ACDP CAS3 add key-12

Here select Key 5 to program

Yanhua ACDP CAS3 add key-13

Note: Gray number is used for the original key

The black numbers are available for calculation

Pop-up: It’s one of keys available. If you enable a new key, the original key will not work anymore.

Yanhua ACDP CAS3 add key-14

Select a method to generate a dealer key

Here: add a new key with a working key

Yanhua ACDP CAS3 add key-15

Check if the key is a smart one or not. If yes, you have to choose Key 1-3

Here: it’s not a smart key

Go to add a new key

Insert the blank key to program

Yanhua ACDP CAS3 add key-16


ACDP successfully programmed a new key

The generated CAS data includes the new key info.

Pls go to write new data into CAS

Yanhua ACDP CAS3 add key-17

File is backup

Upload file (will be written into CAS...DLRKEY...bin)


Step 3: write new key data into CAS

Insert the original key before you’re gonna to write data into CAS

Yanhua ACDP CAS3 add key-18

Go to update key data

Select the correct bin file

Yanhua ACDP CAS3 add key-19

Select a method to generate a dealer key

Here: add a new key with a working key

Updating new immo data

(writing the key data into CAS)

Immo data is updated successfully.

Yanhua ACDP CAS3 add key-20

Backup data

Please install the CAS into the car and try the new key to start.

Yanhua ACDP CAS3 add key-21 Yanhua ACDP CAS3 add key-22

The ELV is faulty; you should synchronize it
