What is this? Blue+black plastic thing under dash

Is it plugged into the OBD2 diagnostic plug?

Do a Google image search for 'Karr alarm', some of the images look a lot like the module you have, especially the button with the raised dots on it.

These Karr alarms were dealer or port installed optional equipment that were hawked to the buyer's at the time of sale as dealer installed options.

They're supposedly a PITA to remove, and if they aren't active, you can just leave them be. If it really bothers you aesthetically, you could remove the module from the panel and tuck it behind the panel under the dash, but you'll still have a couple of holes in the panel.

Is that a button battery drawer in the front (blue flat bit?). Could it be a theft device which some car-yards install.

 

You could ask the dealer who sold it?

 

It looks well used, with the scratches on it, whatever it is.
