Car wont start... i know its the ignition

[PlayersExpress]

This is my DAILY DRIVER and I have no other car

Hey guys, the box is also now immobilized due to the ignition. Starter is fine.. im just trying to figure out which part i need to buy to replace in the ignition.

I called Porsche of Westmont and the guy said $160 for the part and refused to give the part number.

Can anyone point me in the direction of the part/number?

Is this the part im looking for??
