If it's an immobiliser problem it won't be the fob battery as that's only for the central locking and alarm. The immobiliser system uses a passive chip in the fob.

Is it original keys? If not you will need a chip programmed.to work with the immobilizer.

I have this issue, just stick the keys in the compartment behind the gear stick close as possible to the centre console. For some reason the radio signal doesn't work especially on cold days. Car was into the garage three times to get it diagnosed but they just held their hands up so I just use this work around when needed.
