How to change the decontacto bombin of a kangoo?

I need help to change the contact bombin of my Renault Kangoo. I am not a mechanic and I do not have a hard. Can I do it alone or is it very complicated? I have the mechanic manual but I can't find the part where I tell me how to extract the hype and change it. Thank you very much, I hope someone can help me.

You have to disassemble the inferior part where the steering wheel goes, then the upper part, but a boil to take out the complete sheet you must take 4 anchor bolts the problem is that only two of these have a hub and the others are smooth from Sincelera or with a dremel make a line to take them out with a palette screwdriver, but hurt your key is encoded? If so, the problem increases.
