Autel IM608 II and Godiag BMW Test Platform Add CAS2 Mechanical Key

Autel MaxiIM IM608 II with XP400 Pro can add CAS2 mechanical and semi smart key on bench.

Use APA109 cable to connect XP400 Pro and CAS2 module, add key with IM608II, and then detect the CAS and key synchronization by Godiag CAS2 Test Platform.

 

For different CAS2 key types, select the corresponding Godiag BMW CAS2 Test Platform.

For the mechanical key, choose Godiag CAS1 CAS2 Test Platform. For the semi smart key, choose Godiag CAS2 CAS3 Test Platform.

 

What is the difference between CAS2 mechanical and semi smart?

For example:

Semi smart: CAS2 (E8x/E9x)- on the left side

Mechanical: CAS2 (E6x)- on the right side

The chip type is similar. The difference is that semi smart type has the long chip marked while the mechanical one doesn’t have.

How to add a key and detect key synchronization?

Here take CAS2 mechanical key as an example.

STEP 1.Connect devices and CAS2 module

Connect Autel IM608II, MaxiFlash JVCI, XP400 Pro key programmer, Godiag CAS2 Mech-Key Test Platform correctly

STEP 2.Read EEPROM and FLASH data

After connection, go to “Programmer” option

Select Chip (EEPROM/MCU/…)>> Chip Reading/Writing>> Immobilizer>> BMW>> CAS2>2K79X>RW>> EEPROM or FLASH>> Read

STEP 3.Add key

Go to “Write key via dump” option and select the corresponding CAS2 module type the same as step 1

Disconnect APA109 cable

Tap “Load data” to select the EEPROM data just saved

Reading key info

Confirm add a key to key 9

Creating data…writing back key

Save the newly generated file

Generate key successfully

autel im608 ii add cas2 mechanical key 12 - Autel IM608 II and Godiag BMW Test Platform Add CAS2 Mechanical Key - Autel IM608 II and Godiag BMW Test Platform Add CAS2 Mechanical Key

The key 9 is used now.

STEP 4.Check if key and CAS module is synchronized

Disconnect all cables on the CAS2 module

Connect Godiag CAS1 CAS2 Mech- Key Test Platform and CAS2 module

Put the key generated into the coil of Godiag Test Platform

Press the START button

The IMMO indicator doesn’t light up, which means the key is unsynchronized with CAS2 module.

STEP 5.Write the key generated BIN file into CAS2 module

Connect XP400 Pro programmer and CAS module again

Select Chip (EEPROM/MCU/…)>> Chip Reading/Writing>> Immobilizer>> BMW>> CAS2>2K79X>RW>> EEPOM>> Write

Select the newly generated BIN file in step 3 and write it into the corresponding chip

Write to chip successfully
