Portable electronic security key for electronic article surveillance device
First Claim
1. A portable apparatus for reinitialization of an electronic article surveillance device for use in affecting an electronic article surveillance device proximate said article, said apparatus comprising:
- a processor;
means, connected to said processor, for communication with said electronic article surveillance device to be reinitialized; and
, means, connected to said processor, for activating a security code reinitialization in said device to be reinitialized wherein a security code stored in said device is set to a preselected value.

Abstract
An electronic key capable of reinitializing or resetting a security disabled electronic article surveillance (EAS) device is provided. The electronic key can be a secure, portable, and battery powered for initializing a secured EAS system'"'"'s security protocol to factory default state, or to another preselected state. The key has its own set of security protocols to prevent unauthorized use and can easily be reprogrammed for a wide variety of other functions including, but not limited to, firmware upgrading, diagnostic testing, and the like. The key can be connected to the programming port of an EAS device and perform a preset reprogramming operation, resetting activated security features. The key could be purchased for customer use, and would be secured by preselecting the total number of uses, such as one use. The one-time use would begin once the key is activated. Activation of the key is also uniquely controlled to prevent its misuse. In one embodiment, the electronic key must detect the interrogation field of a properly functioning EAS exit system prior to becoming enabled. The allowed usage can be limited by time, the number of units reprogrammed, or a combination of both. Once the key has been activated for its pre-selected number of uses and shuts off, only qualified service personnel can reset the electronic key function for further uses.

11. A method for reinitialization, to preselected settings, of a security code of an electronic article surveillance device for use in affecting an electronic article surveillance device proximate said article, said method comprising:
-
activating a reinitialization procedure;
checking if a preselected number of resets allowed has been expended, and if so then stopping, otherwise;
enabling communication with the electronic article surveillance device to be reinitialized;
checking for an indication to proceed with reinitializing;
checking if the number of resets allowed has been expended, and if so then stopping, otherwise;
checking if the electronic article surveillance device is connected, and if so then, reinitializing the security code of the electronic article surveillance device to preselected values;
decrementing the number of resets allowed by one; and
,jumping to the enabling communication step and repeating the subsequent steps. - View Dependent Claims (12, 13, 14)

15. A portable and programmable security reinitialization apparatus for electronic article surveillance devices, comprising:
-
a processor, wherein said processor is battery powered and includes a sleep mode and an active mode, said sleep mode using less power than said active mode for reducing battery consumption;
means for putting said processor into said sleep mode;
means, connected to said processor, for communication with an electronic article surveillance device to be reinitialized; and
,means, connected to said processor, for activating a security code reinitialization in said device to be reinitialized wherein a security code stored in said device is set to a preselected value;
means for putting said processor into said active mode and for generating an interrupt to said processor for activating said security code reinitialization; and
receiver means for sending a second interrupt to said processor after receipt of an electronic article surveillance transmit signal at a preselected frequency and threshold, said processor activating said security code reinitialization only after receipt of said second interrupt. - View Dependent Claims (16)
