Hey Everyone,

I see my Defender has a security bulletin N864 but I'm not finding much information on it. From what I know if you do it you need a whole new module at a cost of thousands of you lose your keys, and they can't add keys to it.

Does anyone know more about it?

 

IIRC, this has been around for a while and it was because of the theft issues in the UK that caused JLR to only allow 2-3 keys to be programmed per vehicle.
