Need Replacement Key Help...

Hey All, I have an ongoing drama that['s like a lifetime movie & really could use some advice as we're at a dead end of sorts...

My girlfriend kicked out the ex & he managed to take both key sets to her 2014 BMW 328xi. Both of their names are on the loan but only his is on the registration (here in North Carolina) and the court that put the restraining order on him had granted her the car and ordered him to return the key. He's lied saying he "mailed it" (BS) and while she goes through the courts to force his hand, she is a single mother with no car, no funds (he took those) and bad credit. Here's what we've tried....

Local Locksmiths - got one out that specialized in BMW keys/keyfob programming - after quoting $450, tried but got stopped when programming by the computer - said her model was one of only 3% that had to be done at the dealer due to BMW security measures. 

Local Dealer - quoted $450 but would not register with out her name on the NC Registration (while same last name, only her ex is on NC Registration).  

Although the court has ordered him to give her the key, he's going to play this out as long as it hurts her and deprives her of the key. She can't get it re-registered without re-financing to which she can't do as he's already done a number on her credit score also (real winner he is). Any ideas would be much appreciated - would it help to bring the dealer all of the court paperwork? Go to another dealer? Was the Locksmith correct or perhaps mistaken on that whole 3% thing? Just at a loss how to get her a key for a car she's making payments on & desperately needs....

Thanks all
