Having a problem sometimes, having unlocked using the remote then finding on turning the key it doesn't start, nothing there, no noise, it's not the battery or starter motor. If I then press remote locking then unlock, or it seems any button on the remote, I can be lucky and it starts. Appears that the immobiliser isn't being switched off by the remote when unlocking. Am I correct in thinking this is the reason ? Any thoughts would be gratefully received. Thanks.
