Here comes guide on how o program a new spared key for BMW CAS3/CAS3+.Hope it helps!



VVDI2 Key Programmer

A laptop



First connect VVDI2 with car and use the old key to turn ignition on. Open the software when I click Connect it automatically show me car information and “connect OK”.


Click Key Learn


Click Get Key Info and I see two options: one add key, one lost all key. I choose Add Key then NEXT.


And it says the dealer key should be taken away. So pull out the old key and I click OK.


It read out all key information. I click Save Key Info below to save the original key data.


Next I choose KeyID3 and click Prepare dealer key with programmer.


It asks me to put new key into programmer. So I put the new key into VVDI2 coil.


Then it asks if the key has keyless, I say no.

New key is made but locked. So as the tips I use the key to start car.


Yes. Car starts successfully as I expected!
