When working with BMW/Mini CAS3 keys, many locksmiths often ask: Can the VVDI Key Tool Max Pro unlock a Mini CAS3 key even if this specific type is not listed in the device menu?
Officially, if a key type is not included in the current VVDI Key Tool Max Pro supported list, successful unlocking is not guaranteed. However, one experienced Max Pro user recently shared a practical test that achieved success — though it should be noted this is at your own risk.
User-Tested Method: Unlocking Mini CAS3 Key with Key Tool Max Pro
According to the shared review, the crucial requirement is that the key PCB must match the diagram in the VVDI Max Pro Special Function → Remote Renew section. An incorrect PCB layout will result in failure.
The user followed these steps:
- Open the diagram in K2.
- Connect the renew cable according to the K2 wiring diagram.
- In the menu of Key Tool Max Pro>>special function>>remote renew, manually select 5WK49125E Series 868MHz.
- Perform Unlock.
- The operation completed successfully.
Important Notes & Risks
-
This method is not officially listed, so results may vary.
-
PCB matching is essential — even a small difference can cause failure.
-
Always test on a spare key or non-critical key first.
- Proceed only if you fully understand the risks.
Although the VVDI Key Tool Max Pro does not officially list Mini CAS3 key unlock support at the moment, this user case shows that unlocking may be possible under the right conditions using the K2 diagram and the 5WK49125E 868MHz option.
For professional locksmiths dealing with BMW/Mini CAS3 systems, this shared method may offer a useful workaround — but remember: test at your own risk.
