locking wheel nuts

[bazza_]

I bought my clio a few weeks back, when i got it from the garage i was given the locking wheel nut key which i just threw in the glovebox until yesterday when i needed to use it, only then did i realize that it's completely buggered as the pins inside are snapped off, all's i need to know is if this was a type of bolt used as new from renault and can i get another from a dealers? would they be able to order one just from the original broken key or am i going to need to pay a garage to remove the offending bolts?
