Radio, dash, windows staying powered after taking out key

[superskid]

When I take the key out of my 2001 Boxster S, the radio stays on and everything else still has power to it.

I though I remembered the key switching popping out a bit when removing the key in order to turn it off, but now it doesn't and it feels a bit stiff.

After a few minutes of wiggling or shaking the key violently when its 95% pulled out, I can get everything to turn off properly, but it is definitely a pain.

Should I try lubricating with graphite or something else? Otherwise what part do I order and instructions on the install please?

I am hoping that I can get away with replacing only the electrical portion of the switch, as not sure I can tackle the full steering lock mechanism.

Thanks,
