This keyboard is an insert, [https://www.amazon.com/Satellite-C55-C5246-C55-C5240-C55-C5241-keyboard/dp/B01N40J9B0|looks like this]. The shell must be opened and the backing sheet removed then you lay in the new keyboard . The connector is the same as other keyboards just that the keyboard itself is attached to the face plate by a dozen plastic dowel pins . Take care when pulling the keyboard off the dowels that you don't break the dowels. Hope this helps
