6) Wide Programmer Compatibility – Works with Xhorse Key Tool Plus Pad, VVDI2, BMW VVDI BIM Tool, CGDI BMW, Lonsdor, and OBDSTAR devices.
7) Complete Package – Includes 1pc CAS2/CAS3 test platform and 1pc OBD2 to DB25 cable – ready for immediate professional use.
Important: This platform supports magnetic semi-intelligent or smart keys only. It does not support mechanical key CAS2 and cannot be used with diagnostic equipment or with GT100 / GT100+. It also cannot work with Autel devices. For Autel, Lonsdor, and OBDSTAR devices, data cannot be read and written through the OBD2 bench method, because these devices cannot perform 100kb CANbus independent communication with the BMW IMMO module. For these devices, you can only use a programmer to read out CAS2/CAS3/CAS3+ data, perform key matching, and then use the GODIAG CAS2/CAS3 test platform for key synchronization detection.

GODIAG CAS2 CAS3 SER Semi Smart Test Platform is a dedicated device developed for BMW locksmiths, maintenance engineers, and CAS2 / CAS3, CAS3+, CAS3++ programming engineers. It can cooperate with key programming devices such as Xhorse Key Tool Plus Pad, Xhorse VVDI2, BMW VVDI BIM Tool, CGDI BMW, Lonsdor devices, and OBDSTAR devices to perform all-keys-lost matching or key addition operations. This product is suitable for magnetic semi-intelligent or smart keys.
Note: The GODIAG CAS2 CAS3 SER Semi Smart Test Platform does not support mechanical key CAS2 and cannot be used with diagnostic equipment or with GT100/GT100+. It cannot work on Autel devices. For Autel, Lonsdor, and OBDSTAR devices, data cannot be read and written through the OBD2 bench method, because these devices cannot perform 100kb CANbus independent communication with the BMW IMMO module. For these devices, you can only use a programmer to read out CAS2 semi-intelligent / CAS3 / CAS3+ data, perform key matching, and after successful matching, use the GODIAG CAS2 CAS3 SER Semi Smart Test Platform to perform key synchronization detection.
GODIAG CAS2 CAS3 Test Platform Features:
1. Detect CAS and key synchronization.
2. Solder-free matching CAS2/CAS3 serial smart key.
3. CAS data reading, writing, and programming.
4. All keys lost / adding keys matching.

GODIAG CAS2 CAS3 Test Platform Functions:
1. Check whether the CAS2 / CAS3, CAS3+, CAS3++ modules and magnetic semi-intelligent/smart keys are synchronized.
2. Cooperate with key programming devices such as Xhorse Key Tool Plus Pad, Xhorse VVDI2, BMW VVDI BIM Tool, CGDI BMW, Lonsdor devices, and OBDSTAR devices to perform all-keys-lost matching or key addition operations.
3. CAS2 / CAS3, CAS3+, CAS3++ module diagnostics.
4. CAS2 / CAS3, CAS3+, CAS3++ module programming.

Product Structure:
(1) Check the start switch.
(2) IMMO synchronization detection indicator light.
(3) CAS module key induction coil indicator light.
(4) Power indicator light.
(5) Key identification port.
(6) CAS module 41PIN connector.
(7) CAS module 14PIN connector.
(8) Analog start-stop switch.
(9) Start/stop button light.
Note: Can not support mechanical key cas
Module and Key Synchronization Detection:
Check whether the CAS2 / CAS3, CAS3+, CAS3++ module and the magnetic semi-intelligent smart key can be synchronized:

Step 1: Connect the CAS2/CAS3, CAS3+, CAS3++ modules according to the connection diagram.

Step 2: Put the key into the key sensing area.
Step 3: Connect the power supply and the corresponding power indicator light will light up. The start/stop button light is on. The coil sensor light will flash.
[This indicates that the module can send out the key sensing signal normally. If the key and the module are synchronized, the light will flash regularly or stay on. If the key and module are out of sync, the flashing will be irregular and will stop after one minute.]
Step 4: Press the start switch.
[If the key is synchronized with the CAS module, the IMMO synchronization detection indicator light will light up and the internal buzzer of the machine will sound. If the key is not synchronized with the CAS module, the IMMO synchronization detection indicator light will not light up and the internal buzzer of the machine will not sound.]
Step 5: Press the analog start and stop button; the IMMO synchronization detection indicator light will go out after 3 seconds. Press the analog start/stop button again and the IMMO synchronization detection indicator light will light up.
The following uses the Xhorse VVDI2 device to perform BMW CAS2/CAS3, CAS3+ CAS3++ semi-intelligent/smart key programming and matching operations:
1. Connect the CAS2/CAS3, CAS3+, CAS3++ module and the key programming diagnostic device according to the connection diagram.
2. Select “key learn—CAS Key Learn—Connect”.

3. After successfully identifying the CAS information, select “Get Key Info” and “Save Key Info”.

4. Select an unused key position; be sure to select the “prepare dealer key with programmer” menu, and use the VVDI2 key programmer to generate the key. If the key is placed in the GODIAG CAS2 CAS3 SER Semi Smart Test Platform key sensing area, the dealer key will not be generated.


5. After programming the dealer key, put the key into the GODIAG CAS2 CAS3 SER Semi Smart Test Platform induction port for testing. For test steps, please refer to “Synchronous Detection of Module and Key”. If the IMMO light cannot light up, enter the VVDI2 menu “Key Learn—CAS/EWS Information—Connect—Synch DME-CAS or Synch CAS-ELV”.
[When performing synchronization, the key must be placed in the key sensing area of the VVDI2 device.]
