A device to prevent removal of fuel and oil caps includes a pin having a shaft with a first and second end; a head at the first end of the shaft; a locking element at the second end of the shaft; a pad having an adhesive surface that fixes to the cap; a grommet that forms an aperture in the pad that receives the shaft of the pin so that the pad rotatably retains the pin to the cap; and a cover that is rotatably retained over the cap by the pin and the locking element so that the cap generally covers the cap and rotates independently from the cap, thereby deterring removal of the cap.
