have a 1996 a4
the lock cylinder on the drivers door has snapped in the housing so half of it withdraws each time i lock the door (although it still locks

obvioulsly want to repalce this , but want to do so without replacing all other locks on the car so and use the same key

where there only a certain number of key combos issued so that i would be able to just get a repalcemenmt cylinder to match the others ????
