How can I replace the ignition switch in my Audi 80?

I recently purchased an Audi 80 and the ignition switch seems to be faulty. I am looking for a way to replace it myself. Are there any specific tools or steps I need to take?

First, you will need to disconnect the negative battery cable and then remove the steering wheel. You will also need a specialized tool to remove the lock plate. Be sure to disconnect any connectors and ignition switch wiring before replacing the old switch.
