locking nuts key-problem

hi brought the 197 with locking nuts from the dealers and all i got was a small box of normal nuts and two hollow ones that look like adjustment for the brace but no key :S and i dont know how to take off the locking nuts however the dealers can get th ewheels off to swap them over so any help with this matter would be appreciated
 
take it to a tyre place and get them to get them off and then buy some better quality ones as the dealer ones are pants.
