the red light is working on fob but not working doors or immobileizer

as far as l know, you cant re-code renault keys. you have to get a new one.

i will go and read more about it and get back to you.

edit: all keys made by renault after 1998 are non-reprogrammable. you could ask renault to try and re-synch the key. that is different from re-programming.

bring your Chaise no to a renault dealer will give you a code to over ride immobilizer . then reprogram key or get them to do it
