GODIAG CAS2 CAS3 SER Semi-Smart Key Test Platform
The GODIAG CAS2 CAS3 Test Platform is a professional bench-testing solution developed for BMW locksmiths, immobilizer technicians and CAS module repair specialists.
It provides a convenient connection between supported BMW CAS modules, keys and compatible programming equipment. The platform helps technicians test module operation, verify CAS-to-key synchronization and complete supported key-learning procedures without installing the CAS module in the vehicle.
Main Features
• Supports BMW CAS2, CAS3, CAS3+ and CAS3++ modules
• Designed for magnetic semi-smart and smart keys
• Detects synchronization between the CAS module and key
• Provides solder-free connection for supported CAS2/CAS3 operations
• Supports CAS data reading, writing and programming when connected to compatible equipment
• Assists with key addition and all-keys-lost procedures
• Allows CAS key-data backup using a compatible programmer
• Helps evaluate CAS module operation on the bench
• LED indicators and an internal buzzer provide synchronization feedback
• Suitable for professional locksmith and module-repair workshops
CAS and Key Synchronization Test
After connecting the supported CAS module, place the programmed key in the platform’s sensing area and connect a suitable power supply.
The coil indicator shows whether the CAS module is transmitting a key-detection signal. When the key and CAS module are correctly synchronized, the platform’s IMMO indicator illuminates and the internal buzzer sounds.
This allows the technician to verify the completed key-matching operation before reinstalling the module in the vehicle.
Compatible Programming Equipment
The platform can be used alongside compatible professional BMW key-programming tools, including:
• Xhorse Key Tool Plus Pad
• Xhorse VVDI2
• BMW VVDI BIM Tool
• CGDI BMW
• Selected Lonsdor programmers, subject to operating limitations
Compatibility and available functions depend on the programmer, software version, CAS type and selected working method.
Important Compatibility Notes
• This is a test and connection platform; it is not a standalone key programmer.
• It does not support mechanical-key CAS2 modules.
• It cannot be used with GODIAG GT100 or GT100+.
• It is not intended to work as an ordinary vehicle diagnostic interface.
• According to the current GODIAG product information, AUTEL and OBDSTAR devices are not supported.
• Lonsdor equipment cannot perform CAS data reading or writing through the OBD2 bench method because of its independent 100 kbps CAN communication limitations. CAS data must first be processed with a suitable programmer, after which the GODIAG platform can be used to test key synchronization.
• Always confirm the exact CAS version, key type and programmer compatibility before ordering.
Typical Applications
• Testing BMW CAS modules outside the vehicle
• Checking whether a programmed key is synchronized with the CAS module
• Adding keys with compatible programming equipment
• Supporting all-keys-lost procedures
• Reading, writing or backing up CAS data using a compatible programmer
• Testing repaired or replacement CAS modules before installation
