....my rota slip stream wheel lock key broke and i dont know where to find another one if anyone can help it would be much appreciated

 

Take it your referring to your lug nuts? What brand do you have?

 

If you know the brand, order one from that company. Or shops will do it or you could weld a bolt to the nut...

 

Ouch this happened to me few years back, had to literally make a good slit good enough to have grip and keep pounding away till it came loose.

 

that sux, happened to me before too, its a real pain to get the lugs off especially since the holes in aftermarket wheels are usually sunk down into the face of the wheel so normal lug nut removal tools won't work

i ended up buying another set of tuner lugs that used the internal style key and had to grind down the key itself just to get them off

now i use a regular style hex lug nut instead of the tuner lock style
