The clicking noise you describe is the Anti-theft system scanning for your key fob. The same noise can be heard anytime you press the pads on the trunk or doors, but since you're outside the vehicle, you can't hear them. (If you want to try it, put your top down, turn off the engine, then get out and try to open the trunk without the fob nearby.)
If you have any other questions, I'll try my best to answer them. I am a Cadillac dealer who has attended both the technical college and ride+drive events with Cadillac, so hopefully I can be of some assistance on this board.
