A novel locking mechanism and specific applications for same are disclosed. One aspect of the invention provides a product security system having a locking mechanism for preventing sliding movement between a slidably juxtaposed product container and product container locking structure, and a separate decoupling unit. The decoupling unit has a frame adapted to receive the slideably juxtaposed parts, and means within the frame adapted to disengage the locking mechanism, thereby permitting sliding decoupling of the parts. The locking mechanism has a magnetically attractable pin in a blind hole in the first part and a detent opening or recess in the second part. The pin is moveable between a first position in which the pin enters the detent, thereby preventing sliding movement between the first and second parts, and a second position in which the pin is retracted into the blind hole from the detent, thereby permitting sliding movement. Means are provided for biasing the pin into the first position. One particular embodiment of the invention is a locking kit for a box having a hinged lid, such as a video cassette box.
