right well that makes it code 2 rolling code
the codes in your keys are changed every time you turn the ignition on with them
if the lock smith made a direct copy of your key when you try the new key it will change the code in it and the matching code in the body computer
therefore when you try the key he made the new one from it's code is now irrelevant you may as well chuck the old broken key it is now worthless there nothing you can do with it
