hatch door

[yaris9876]

I see how it works now... but on mine the white plastic thing wont go in the unlock position.
I can leave it unlocked and lock it but the key just cant force it over to unlock
.... I lubed it well with wd40 but
still wont go... Would it be a big deal to replace the whole key drum and plastic thing with an aftermarket assembly that would fit in there??The drum seems to be held in my 2 bolts..not 1

You can replace it, but unless you have a locksmith modify the existing one you will need a separate key for the hatch. I have a couple of spare ones if you need one, as I changed two of mine over to using the Scion IQ hatch knob with switch and have it electrically actuated:

Also, try a different key, if you have a spare, as it may be that your key has worn too much for the hatch lock.
