Help! How do I get these wheel nut locks off?

[blanes]

On a K11 SR, they are smooth cylinder with little groove on top,
There is a little plastic thing in the tool kit that looks like a bottle top but cant work it out.

Im guessing I must have to line up a groove somehow

Please if you done these before let us know,

I want the wheels off ASAP, Any help very appreciated

They are Nissan ones, I'm gonna get a sledgehammer in a minute, anyone else please! I was thinking it might be a magnet thing, they just spin round like a be'ach.

Sheared bolt sockets whatever they're called. They'll get it out

Done it!!!! If anyone else has this problem

Here you go for future reference - There is a little black bottle top thing, this goes on the cylinder, you turn it till it grips, then you pull the cylinder and the cap, It is a a magnetic catch type operation, what a git for anyone who loses the device, I think I'll bin these.
