Intelligent keyfob management system
First Claim
1. An intelligent keyfob management system including at least one RF transmitter, a RF receiver, and a microcontroller, comprising:
- sending a RF signal having unique serial data from a transmitter;
receiving the RF signal in a receiver and converting the RF signal to a digital signal;
transmitting the digital signal with the unique serial data from the receiver to a microcontroller;
providing an editable microcontroller memory including a look up table accessible by an external programming device;
verifying whether the unique serial data from the transmitting step matches data populated in the look up table; and
performing or refraining from performing a command requested by the transmitter, based on the data in the look up table.

Abstract
An intelligent keyfob management system (300) is disclosed. The system (300) includes the steps of: sending (302) a RF signal having unique serial data from a transmitter; receiving (304) RF signal in a receiver and converting the RF signal to a digital signal; transmitting (306) the digital signal with the unique serial data from the receiver to a microcontroller; providing (308) an editable microcontroller memory including a look up table accessible by an external programming device; verifying (310) whether the unique serial data from the transmitting step matches data populated in the look up table; and performing or refraining from performing (312) a command requested by the transmitter, based on the data in the look up table.
The system (300) is particularly adapted for use with security locks for containers, trailers, and delivery systems using emergency exit doors, and provides an enhanced tool in managing, monitoring and administering RF devices, and particularly keyfobs, typically from a remote or dispatch office location. The look up table can be used to program when an RF device or keyfob is operable or non-operable, and a logging feature can time stamp each device'"'"'s usage or attempted usage, for later retrieval and analysis, which can be useful for management of RF device fleets and field and delivery personnel.
