FAQs

• Q: Can BMW MULTI TOOL do BMW cas3 and cas3+ keys? For example, the 868 MHz key.
  A: yes, BMW MULTI TOOL can do most kinds of BWM keys.

• Q: Can BMW Multi Tool V7.4 do the EWS ?
  A: Yes, but you should withdrawing the EWS when you want to read the data.
  Reading the data you should have a CAS socket.

• Q:I lose all my keys,can I use it for my bmw car?
  A:It depends,you need tell me more detail about it,if your car is CAS3,maybe can not do.

• Q: When I do the key programming, the system remind me failed at the security access, what should I do?
  A:

  1. add key obd;
  cas3+ encrypt version -> no need to update CAS (no need for key cycling)
  cas ISTAP4x version -> need to update cas (no need for key cycling)

  2. lost key obd;
  cas3+ encrypt version -> no need to update CAS (need to cycle key UPTO 16 times)
  cas ISTAP4x version -> need to update CAS (need to cycle key UPTO 64 times)

  3. add key dump method (lost or working key);
  cas3+ encrypt version -> need to write back to CAS (needs either -working key / known ISN / ECU dump / or cycle UPTO 16 times)
  cas ISTAP4x version -> no need to write back to cas (needs either -working key / known ISN / ECU dump / or cycle UPTO 64 times)
  So the 64 cycle is really to save you having to downgrade the CAS but you still need to manually read the CAS for this option.
  For me this is still the best way as theres no way I would downgrade the CAS (unless you made it very clear what this meant to the client)
