how do i open hatch on 2000 toyota sienna that has broken handle

To open from the outside, make sure doors are unlocked place a screwdriver, long and thin, into the slot that the handle passes through the door on the right side. Raise the handle of the driver, and you should be pressing down on a cable that operates the latch. the door should release. If you cant do that, from the inside, remove the two side trim pieces. Then remove the inner door panel, One screw under plastic cap on handle, one under cap on strap... and pop off all plastic buttons(hidden) between the door and cover, a 1" putty knife will work for this. You will see the cable that used to connect to the handle. Remove the cable by pulling it through the slot(apparent when you get to it) and now remove the two screws that hold the handle on. Also, you have to remove a screw from the passengers side of the cover plate over the handle. the plate will slide, and it will come off. replace the handle and etc.
