No Key for Wheel Lock on 8th Gen Civic Hybrid
 

I purchased a 2006 Honda Civic Hybrid from a private party approx 2 years ago. It's time to change the tires and my local Honda dealership (South Florida) tells me that my wheel lock is one they have never seen before and I will have to pay ~$250 to have the lug nuts cut out to remove the tires. Can anyone point me to the right tool/key to remove my tires? (photos attached).
