Sorry to hear that mate, 3x attempts is a major FAIL in my opinion. Was a good try anyway... now we know NOT to use them
Got a blank key two years ago fom eBay and got it 'copied' by the key guy down the street. Most of them have the machine that trace the original and simultaneously cut the other. $5. Look in your Yellow Page and find a locksmith near you and he'll put you back on track.
Call your P car dealer and ask them where they get theirs cut is another idea.
