Rear hatch latch revisited

[finaltable]

When I first turned the key counterclockwise I thought the cylinder had come loose. I looked in my owners manual (which I still have, along with the original window sticker from the previous owner) it describes the functionality in detail as Toyota recommends you put the hatch in lockout mode when leaving the vehicle.

My guess is that the lockout mode is there because with the Supra not having a trunk anybody can see what is in the back of the car. Since putting it in lockout mode disables the lever by the driver's door even if someone were to break in and unlock the doors they couldn't open the hatch to take anything of any size out.

It definitely does this by design, I am just stuck because the mechanism isn't working with the master key.
