CAS Version Comparison for Key Operations

Key Replacement Scenarios

Working Key OBD:

• CAS3+ Encrypt Version: No need to update CAS (no key cycling required)
• CAS ISTAP4x Version: CAS update required (no key cycling required)

lost Key OBD:

• CAS3+ Encrypt Version: No need to update CAS (key cycling required up to 16 times)
• CAS ISTAP4x Version: CAS update required (key cycling required up to 64 times)

Add Key via Dump Method (Lost or Working Key)

• CAS3+ Encrypt Version: Requires writing back to CAS (requires one of the following: working key, known ISN, ECU dump, or key cycling up to 16 times)
• CAS ISTAP4x Version: No need to write back to CAS (requires one of the following: working key, known ISN, ECU dump, or key cycling up to 64 times)

The 64-cycle method primarily avoids the need to downgrade the CAS module. However, manual reading of the CAS is still necessary for this option. This remains the preferred approach, as downgrading the CAS is generally not advisable unless the implications are clearly communicated to the client.
