It is a BMW 5 series year 2012. We need to program two new keys for this car. Some people complain that there are lack of information online on how to use Launch X431 IMMO Plus. We will show basic steps one by one how to program key for BMW with CAS4 using Launch X431 IMMO Plus or IMMO Elite together with x-prog3. Program BMW CAS4 all keys lost using Launch IMMO PLus with XPROG3 (how to solve IMMO Plus fail to generate BMW CAS4 key): Now we are in the main menu of IMMO Plus. So to start the process we need to go to Immobilizer. Then we are going to the BMW, in that page you can see a vehilce list for all supported BMW models from year to year with immobiliser with a description what immobilizer system are on the cars so in case if you need to check if you can do something or you can’t. You can just go to the tab and find your car and know if you could do it so then press on the next. What comes up is connection diagram of X-prog3 to the car. This is very simple you can do it
If your Launch DBscar VII or Smartlink VCI says “Diagnostic connector connection is abnormal” (image attached), here are possible resolutions. Do as the Launch X431 tablet said, Select reconnect 3 seconds after the connector restarts successfully (a beeping sound). If it’s legitimately losing connection to the VCI, try VCI Firmware Fix in settings . For Launch X431 V+ V5 , PRO3S+ v5 , CRP919E BT , APEX etc with DBScar VII connectors: Go to User Info->Firmware Fix-> Press Firmware Fix ->Scan bluetooth connector For PAD V , PAD VII , Pro5 smartlink : Go to User Info->Fix connector firmware/system-> Fix Connector Firmware or Fix Connector System If SmartLink VCI turns black screen, do a firmware fix. Make sure you have a good connection, and that the vehicle voltage is good.
