1. A detacher for unlocking a security device having a detectable security tag therein, the security device having a magnetically-actuable locking mechanism, the magnetic-actuable locking mechanism including a magnetic latch which can be moved from a locked position to an unlocked position by application of an external magnetic force, a latch-mating element for engaging with the magnetic latch in the locked position, and a flexible element for providing a resistive force to bias the magnetic latch into the locked position, comprising:

  • a magnet configured to exert a magnetic force on the security device, the magnetic force exerted by the magnet having a strength sufficient to overcome the resistive force of the flexible element to allow the magnetic latch to move from the locked position to an unlocked position;

    a motor coupled with the magnet;

    a housing comprising a nest, the magnet and motor disposed in the housing, the motor arranged and configured to cause movement of the magnet with respect to the nest; and

    a security tag interrogator disposed in the housing, the security tag interrogator including a security tag antenna and a security tag reader.
