My SE model doesn't have trunk door lock button like this picture. So I want to upgrade it myself, I baught like this button. I tried the button change, big square button is working, but circle button(door lock button) isn't work... So I want to see the XSE or XLE trunk disassembly pictures. Is there anyone who has the picture? And I found a trunk door locking part assembly guide like this. With this pictrure, I changed only 84840G, So I think that I should have to buy and install 89222A and 89747E. Is there anyone has a picture of 89222A and 89747E?? And if I install this, is it work well directly, or I have to pair it to my remote key??
