my old ray's lug had cut that required specific key to fit lug. my key had # engraved on the key, which was like #15 or something.. anyways, every # the teeth moves to the center of the lug.....

^^^ sorry for my poor english.. it might not make sense.

 

I've used my key on two different set of locking lugs too

 

found a better pix @ archive

 

Bronze TE37...

 

Anybody want to let me use the key for 5 min. Ill remove them in front of you and return the key...

 

I think there is only one key. You can use mine if you still need it.

 

Yup mine were locking as well...
