Peugeot scooters have been broken up, castle itself swapped?

Hello guys, my Peugeot Speedfight 4 scooter was broken up the days of the night, so now the helmet compartment lock and the steering wheel lock no longer work.There is a lock set in the net where all the parts that you would need for the exchange are included.. my question would be now, can I change that myself or do this a workshop? So you need some special tool or something for that kind of thing? Would really be great if we could give someone a quick feedback to give 🙂 Lg
