Hi Martin,

Just a word of caution, I bought a blank new key a little while back complete with PCB and PCF7931 transponder chip. The PCB was programmed to the car with no problems, but the transponder chip wouldn't play ball. In the end, I bought another transponder chip, this time PCF7935, and it worked perfectly.
