How can I get into it?

Hi Mr Donohoe .

Best way is to have a battery jump pack or jump cables from a friends car and then with the cables get under the car and connect the red (POS) cable to the main positive cable on the starter motor and the black (NEG) cable to the block of the engine ,
This will give the system power so you can open the doors .

Here is a diagram of the starter motor and where to connect .


Need further assistance then please get back to me if needed.

Please rate my help a 3 to 5. " If you are not satisfied please don't rate."
