There is no way in with the key. There is an emergency method but you won't get it published on here for obvious reasons. Suggest you check the battery in the remote. If not you should contact the owner for help.
Nobody is going to tell you how to get into a Tuscan on an open forum and not owning one means that there is even less chance. Best contact the owner of the car.
I wasn't looking for a way to 'break in', just seeing if there was some secret key hole. So thank you to the first poster who told me there isn't one, rather than just suggesting the mods delete the thread.
