If you have CA and you leave the fob in the trunk and close it, it will re-open the trunk if it does not sense another fob outside. Yes, I have tested it without the metal key in the fob.

I have not tested to see if the DOORS will unlock themselves without another fob outside, but that scenario is hard to come by in the real world. Usually you would use the CA ridges on the handle to lock, and the ridges dont work if the fob is not outside of the car with you. Or press the lock button on the fob, which obviously requires the fob to be in your possession.
Or you can just taste the battery out of the fob.
