i dont know if it has a mechanical key lock or not.
but can u acsess the ignition wires? if yes, then get a tester and see which ones are constant 12+. take connect the 12 volts to each of the wires that did not have 12 volts.
u'll actually end up using 3 wires in total. one will the constant 12+
the second will be the one that turns on all ur electronics in the car (meaning when jump that wire w/ teh constant, it will light up ur speedo and etc.)
ok connect teh constant and the second wire (keep them connected in a way that they dont lose the connection)
then connect ur starter wire w/ the constant which will start ur motor.
if everything is right. it'll start up.
the third is the one that runs ur starter (when u jump it w/ constant)
