Encoding the key of a 2007 Renault Kangoo

I have not changed anything

You have to have a 5A fuse -look if it is not molten

All the fuses are good

When the antiarranque system is operational, the red witness of the flickering antiarranque (slow intermittence; a flash per second). After having put the contact, the key code is transmitted to the central unit of the cabin. If the code is recognized by the central unit of the cabin, the central unit of the cabin and the injection calculator are sent coded signals through the multiplexed network and the anti -rran witness goes out. If the signs emitted by the central unit of the cabin and the injection calculator corresponds, the central unit of the cabin authorizes the start of the motor and the injection is unlocked. Injection does not have any reference code in memory: the sent code is recorded in the memory. If there is no coincidence of the key codes and central unit of the cabin, the system remains blocked. The red the flicked antiarranquetigo (rapid intermittency). The start of the vehicle is not authorized. Attention when the battery is little charged, the voltage drop caused by the solicitation of the starter engine
can reactivate the antiarranque. If the tension is very weak, the start is impossible, not even pushing the vehicle
