Hello Mike

I'd start by charging the battery as you can't get into the car/ boot the other way to do this is jack the car up so you can get under the front.

Locate the starter motor and the large power cable that runs to it - connect the positive battery charger lead to this terminal

then connect the charger negative lead to the metal of the engine block

This should complete the charging circuit and get some power into the battery allowing you into the car
