Volkswagen problem with ignition

Volkswagen problem with ignition, a client came to me with a 2010 Volkswagen that when I key it in the ignition, I went and took out the full brake, and I am a metal key and with a clamp I could open it, when I take out the chucho and put the key I rotate well so I imagine that it was the inside of the brake that the Ignition Switch is Agency a new brake but when I put the screwdriver to turn inside it does not turn the feet that turns to the ignition switch and I cannot ride the chuchu, someone save if to turn this piece Adento del Brake there is some tip or something thickness that you have to do, thanks thanks
