I have just bought a 2003 XJ6, as well as the to usual ignition keys it also came with 2 small keys that look like the ones you used to get with steering wheel clamps or bicycle locks. Can anyone enlighten me as to what they are for? Thank you in advance.

 

Lug nuts?

 

Steering wheel lock that the previous owner didn't sell with the car? Or the keys to a detachable tow bar - I had one on my car and you had to unlock it to remove it with some small keys.
