How to fix 2001 toyota sienna rear door not opening
The inner hatch latch mechanism is seized. You need to pull the door panel with it closed. It will be tight but it will come off without cracking. Spray lube around inside of latch. Get a long screw driver and pry the link from the key. The latch won't release until the key link goes to the unlock position. It will be seized. It is easy to figure which way to move it if you have someone insert the key into the closed hatch and try to move it.
