you can do this many ways, but here is what the real locksmiths do:
they basically have a device that can go down inbewteen the window and the outside of the door (through that little gasket seal) and then they basically pull on a little rod that unlocks the hatch. If you have taken an escort door apart you´d know exactly what it looks like. I´d scan in a pic of the breakdown, but I don´t have a scanner. Hayne´s manual 11-10 if anybody has a scanner and wants to help him out.
