Are you trying to learn key with pcf7946 electonic transpomder ? Or pcf7936 carbon transponder ?
What tool your using to learn key ?
Try to make transponder by dump and test if all fail go to immo off my opinion 
Those renault are very strange 
Did you check antenna coil ? 
The pin from dump is :
BDE1DFF2D979

Can you help to make tranponder from dump ? Or can help with immo off ?

Super big thanks to Raffy :  make transponder by dump with xhorse superchip and then just start the car without adding key ! Again something new learned ! Respect !
