So I lost the only key I had, so I had a locksmith come out and make me a new key, which he did but then told me that his computer couldn’t connect to the ecu in my car, I know the obd works because two days before I had it on a obd2 scanner and it worked fine… so now I have a new key that does nothing, so my question is can I program the key myself? Otherwise I’ll have a great car going to the junk yard for something so simlpe
