Yaris 2012 door lock-unlock problem

If it helps any, I noticed whenever I hit the unlock button that the dome light doesn't turn on anymore. Thanks CTScott for the help

That definitely makes it seem like a body ECU issue. The part number is on a sticker on the back of it. If you stick your phone up behind it you should be able to snap a pic of the label. There are a ridiculous number of different part numbers of them, and from what I have found with a couple I have experimented with, you need the same part number, or the circuitry for driving the proper number of doors, interfacing with the OEM receiver for the keyless entry, etc. will not be present.
