Abstract: A device and method are provided for securing and selectively locking a portable item to a supporting surface. A generally flat attachment plate is connected to a generally flat base plate containing a lock barrel and a lock cylinder. The attachment plate fastens to a device being secured. A securing stud fastens to the underside of the supporting surface such that the shaft of the securing stud protrudes through a hole in the support surface and base plate to extend into threaded engagement with the lock cylinder barrel. The securing stud has a thin flat head which when adhesively attached to the supporting surface prevents the securing stud from being rotated or removed.
