Unfortunately we don't have this vehicle in the USA so I don't have a manual on it but it sounds like you are having a security issue. The start then stall is indicative of a key security issue. Then the not unlocking could be the same issue or just a weak battery in the key. I would suggest starting with a new key and check for codes. If you have a code that will point us in the correct direction.
Sorry I don't have more detail info for your vehicle but this issue is pretty common along a lot of vehicle lines.
