possible causes -
1) wrong connection (take attention on yellow and green wires! In some 3rd party manuals yellow is green and green is yellow for PCFprog,
2) wrong chip type - go to menu, boot -> choose correct one
3) battery is removed from key?
4) some chips like PCF7941 need a very little power, so sometimes EMI field around PC is enough to power them on. Solution - try to short coil, place 10k...100k resistor on power wires etc...

boot fail = no connection or wrong connection
boot failed = device cannot boot board (such as 41 from IYZC01C)
