Help figuring out what this locking lugnut is?
 

Hey everyone! First post on here and hopefully first of many since I just bought my first Maxima yesterday!

When I went to go pick up the car, it has the dreaded locking lug, and the previous owner said he lost the key to it.

I'm wondering if any of you can help me figure this out. (2005 SE)
