Many months ago I cut one of my keys open because I could not get it to initialize the power locks. I test ed the battery it was good then I went and initialized the circuit board to my car, it worked. This was a probably 6 months ago. So then I started to think what if the micro switch buttons just need a bit more pressing down from the buttons on the key shell. The buttons on the key wheel are not loose and do not fall out there hinged but really don't allow for much movement when pressed. I put the circuit board in the half that has the buttons pressing the circuit board firmly in place and operated the buttons, the key worked perfectly. What I think I'm going to do is remove a little of the plastic that supports the switch circuit board and that will bring it closer to the bottom of the plastic buttons in the key shell.
