Mechanical key wouldn't unlock door

Trips

Does the mechanical key lock the glove box? If it does then yes the warranty should cover the issue with the door lock.

If it doesn't? What I think happened is that car was traded in from someone who changed out the handle for whatever reason and didn't exchange the lock since they primarily used the fob.

If this is the issue? You would have to pay for either replacement the door lock and glovebox or just having the right key made for both.

EDIT: read your original post more closely and it should be a warranty issue.
