Hi Tom, the locking wheel nut key in the set you purchased is only suitable for the locking nuts in that particular set. It is highly unlikely that the same key would fit the wheel nuts on your own car unfortunately (there are a total of 26 combinations).
Just like the key for a car, they are all cut in a unique way so that you can't just use any key from any random set to remove the nuts. Anything otherwise would be a security risk.
If you have lost your original locking wheel key and need the locking wheel nuts removing then we offer a removal service free of charge using our Master set for any previous customer at our warehouse in Ilkeston, Derbyshire. Please get in touch if you would like us to help. Thank you
“Items in good usable order, 1 item ordered wrongly advertised, but they contacted me prior to dispatch, offered that item and the correct item at no additional cost.
Can't speak more highly of these guys.”
“I have ordered too many parts lately to comment on any specifically. What I can say is that if you need a Jaguar part quickly, anywhere in the world, it will arrive within the week. I live on a little island off the Pacific coast of Canada, and I can have a part in my hand in four days, if I choose express shipping. If I have needed help finding the right part, customer service is ON it.”
