Hi

My RR Sport TDV8 3,6 Diesel ( 2007 model ) doesn't start anymore.
I charged and checked the battery ( only 3 months old ) so that's OK.

When I put my key in the ignition , nothing happens...
So I thought maybe my key is faulthy, I've send my key to a company ( The Master Locksmith ) for new battery and they said it's working properly.

Still nothings happens , position 1 and 2 , even the dasboard doesn't light up.

So I think the car ( ECU ) isn't talking with my key.

What could be the problem ?

Thanks in advance !!

Kind regards,

It's not the key.

Just old barrel switch or cjb computer.

Ignition lights should come on regardless of imboliser from key

Ok thank you for the fast response.

I can turn the key to the first and second position , and also further ( For starting the car )
But nothing happens or light up...

What's the CJB computer please ?

Central Junction Box.

It's basically part of the fusebox, which sits behind the glovebox and a computer which controls the cars systems.


Do the cigar/power sockets have power is pos I ?

Yes, the 12V socket works.
Also the radio and screen works fine.

The dashboard only says : Key in ignition , but all the rest of the dash doesn't work...
