Help! i've lost the the bit for my locking wheel nuts so I can't get the wheels off the car. Spoke to the local renault dealer and they say they can't replace it. They tell me I'll have to drill the old ones out and replace with a new set. Is this true? I thought that there would only be a limited number of designs and that if i gave them the chassis or VIN number they would be able to supply a replacement. Anybody got any suggestions?
