Yes, its a loose fit but goes on and most importantly doesnt come off without the key.
Keep the key on your key ring and the spare key somewhere handy, make a note of the number/code and keep that handy too
Every once in a while, spray some WD40 on the key and wiggle it in the lock to keep the mechanism smooth. The last thing you'd want is for the lock to seize up when the disklok is fitted on the steeing wheel! A breakdown man told me that he has to deal with such cases from time to time. But I've had no problem with my Disklok and it's brought me great peace of mind. As a visible deterrent it's potent... I don't think about the £100 I spent any more...
Love the yellow car by the way, unusual to see one, is it standard or your choice?
Regards,
Mike.
