Replace microswitches in remote control/keys

Hello all, my wife’s Clio needs new microswitches/buttons in the remote control. The car can no longer be closed. It is a CLIO III (BR0/1, CR0/1) 1.2 16V (BR0P, CR0P) , 1149 cm3, 101 hp, 74 kW Night and Day. Engine type: D4F H7 Has any of you ever done this ?? Would be grateful for a few tips.
