In the previous post, we’ve demonstrated how to use Xhorse Key Tool Plus and Godiag CAS1/CAS2 Test Platform to add a CAS2 mechanical key with CAS1 hardware. Today we will use Autel MaxiIM IM608II to test.
1.Connect the WHITE connector of Godiag CAS2 Mech-Key Test Platform to CAS2 module
2.Use the CAS1 diagram to read data
2.Select the CAS2 menu to generate dealer key with IM608II key programmer
First, insert the car key into the CAS2 module. It is ejected, which means the key is not matched.
Then, connect Autel IM608II, MaxiFlash JVCI, XP400 Pro key programmer, Godiag BMW CAS2 Mech-Key Test Platform correctly
Go to “Programmer” option
Select Chip (EEPROM/MCU/…)>> Chip Reading/Writing>> Immobilizer>> BMW>> CAS1>2K79X/0L01Y>RW>> EEPOM>> Connection diagram
Remove the component from the vehicle, check the circuit board of the current component and identify the corresponding circuit board, and connect XP400 Pro and CAS2 module via Autel APA109 cable according to the wiring diagram
Read EEPROM and Flash data separately, and save the file
Next, Back to the Programmer main menu, select Write key via dump >> Europe>> BMW>> CAS2>> MC9S12DC256C
Load the original CAS1 EEPROM data just saved
Disconnect APA109 cable
Put a blank key into the coil of Autel XP400 Pro programmer
Select an unused key position (i.e key79) to make key
Confirm add a key to key 7
Start generating key…
Save the newly generated file after generation
The key 7 is used now.
After that, connect XP400 Pro programmer and CAS2 module again
Select Chip (EEPROM/MCU/…)>> Chip Reading/Writing>> Immobilizer>> BMW>> CAS2>2K79X>RW>> EEPOM>> Write
Select the newly generated BIN file and write it into CAS2 module
Write to chip successfully
Finally, insert the key programmed to Godiag BMW CAS1 CAS2 Test Platform to test again, the key can be inserted successfully, which means the key is matched with CAS2 module.
