So what model and year is your car?

How long have you owned it?

You say the key does not work, but you are not specific about what does not work.

Does the key turn in the ignition and does the key unlock the door and trunk?

Does the key just not start the car?

When you buy a key from BMW it is cut and programmed with data in their build database for how the car was originally set up when built. Rarely does the BMW parts group mess up a key, but it could happen.

If someone has changed something in your car, it is not BMW's fault and you would be responsible for the keys you purchased.

What I am a bit unclear about is why a 3rd key was even ordered. After key #2 did not work, alarm bells should have been going off that something major was wrong.

With my $32 software program I can see if the EWS can recognized the key and if any keys are disabled in the EWS. Any decent dealer or Indy should be able to verify this as well.

If I were you, check out this site. I have not used them, but others have had success at a reasonable cost with these guys as I recall -
