speedfight 100

hi i have a problem, i have a peugeot speedfight 100 and it needs a new crankshaft, i have been told im better off just swapping engines, i have been offered an elyseo 100 engine for a good price and was wondering will it fit and also what happens with the immobiliser???? help

 

straight swap, the immobiliser is in the cdi so it doesnt matter what engine it is as long as the wiring is the same, which elyseo engines are

 

thanks mate that was the exact answer i wanted to hear
