So far it looks ok. After erasing process, old card will be rematched with immo, and another will be programmed. Just follow the instructions.
For precautions use battery charger during the process (or better- dedicated power supplier) and save eeprom from uch before.
Once card is programmed to the car, it can't be married with different car, but it can be removed from immo and matched with the same car many times.

Yes, old card will be deleted and after that again matched with car. New card will be programed, whole process take about 3 minutes...

Regards

thanks for your quick answer , is there a specific type or frequency for the cards , or just megane card keys are all the same

The write part of the card reader goes down. My local Renault dealer keeps a good card reader / writer in his tool box, swaps it while he adds a keycard then puts customers own back which has a faulty write part.

i think there is mcu in UCH. Just go to card programming procedure and follow instructions, there no much chance for something to go wrong on megane 2....you can always program old card even if it gets erased
