Anyone recognize these wheel locks?

[SeattleBMW325i]

PO owner didn't give me the key for them, they seem like pretty good locks since they actually need a key of sorts so I hate to cut them off or something. Anyone recognize what they are so I can try to get a replacement key(if possible)?

I had those too. PO never gave me a key and I found them in my trunk. I figured out what they were and tried screwing one onto a lug nut thinking it was unlocked when the lugs were off the car. After picking the lock to get it off, I threw them away just in case I ever got curious again.

I've been searching for a part number but I'm beggining to think they were a dealer installed option.

Hmm, I might end up cutting them off or something, don't know how to pick locks...I really need tires on the Subaru bad, so the M3 gets tires and these tires will go on the Subaru.

Hate to do it but the PO doesn't like to answer anything I ask, even though she seems heavily involved in the BMW community...So I think chances of getting a key are slim.
