Modern Buddy

Hi everyone,
I seemed to have lost my last key for my Stella 4T. Is this all I need to buy to replace the ignition?

And how hard is it to replace this myself?

I also have the number that was on the key. Is it possible to just get key replacements?

Thanks!

Call the shop where you bought it. They can probably make a duplicate.

I think the switch is 4 poles not 8
