Need Help Please to Pre-Code Virgin PCF7947 for Megane 2 I replaced the PCF7947 on a used Megane2 keycard and it now reads as No Transponder! I need to pre code it but dont know how as unless its pre coded and fitted to the keycard I cant read it! I have bought a pre coded PCF7947AT and would like to copy the coding to my own virgin ones ready to fit in used Keycards so I can re use them. I have a few tools inc Chinese Tango and FVDI plus others but need step by step help to read the pre coded chip and then write that info to my own virgin ones. Looks like it can be done without fitting it to a Keycard as the pre coded chip has no signs of solder on the legs! Can anyone teach me how to do this please?
