I'm thinking of buying the appropriate product, I've lost all my keys and live a very long way from a dealer. I want to know if I can program a key through the OBD port using this product when my car "shuts off" after about 1 minute after pushing the "start, stop, engine" button. There is no slot for me to place a key into. I have 2012 BMW 750Lix. Thank you for your help.
