The next problem is with the keys and starting the car, both keys are without batteries so the only way to lock/unlock is by putting the key in the door. It does that fine with no blip of the horn. Now when you put the key in the ignition all the electrics power up and when you turn the key all the way to start her up nothing happens and when you release the key it then locks the barrel. The battery has been fully charged and disconnected until today. The car came with no batteries in the fobs and ran fine then so it's all a bit puzzling.
Does the chip in the key need a battery to work or is it the immobilser which is not recognising the keys?
