MaterKey III MK3 Unlock Peugeot & Citroen PCF79XX OEM Remotes

Q: Can we use VVDI2 tools do keys like Peugeot / Citroen? How can I copy data from a brand new key with PCF7941 to one that was previously coded? Is it possible?


A: Have tried several times to read PCF 7941 from Peugeot ket with PCF79XX adapter and in circuit without success


If you can erase PCF7941, a new personalised file must be loaded to chip, depending on the key and version like MasterKey III MK3 key programmer


Have a look to this how-to’s (via pictures) with MK3 to understand how PCF79XX works:
