I want to add a mechanical key to BMW CAS2 module which has the same hardware appearance as CAS1 and the data inside is CAS2. How to use Xhorse Key Tool Plus to make the key?

You can use Godiag CAS1 CAS2 Mech-Key Test Platform to work with VVDI Key Tool Plus. Refer to the following operation guide.
1.Connect device and CAS2 module
Plug the white connector of Godiag Test Platform into the CAS2 module
(Generally, the white connector is connected to CAS1 module, and the green and black connectors are connected to CAS2 module. As the special CAS2 module is equipped with CAS1 hardware, here need to use the white connecter.)
Connect the test platform and Key Tool Plus via OBD2 to DB25 Cable
Connect the 12V power supply to the test platform
2.Detect if key and CAS2 module is synchronized
Press the Start switch, the START-STOP indicator light on the CAS lights up
Insert the blank key into CAS2 module
The key is ejected, which means the key and CAS2 module is unsynchronized.
