Abstract
An apparatus for simulating keypad entry of an access code into a security system controller. The apparatus comprises at least one electronic key encoded with a electronic key identifier, at least one electronic key reader adapted to electronically interface with the electronic key to electronically transfer data signals therebetween, a security system controller having memory for storing at least one security code therein and operably connected to a keypad for entering access codes thereon, and simulator circuitry electrically connected to the electronic key reader and operably electrically connected to the security system controller, whereby upon presentation of the electronic key to the electronic key reader, the simulator circuitry interrogates the electronic key then translates the electronic key identifier into an access code. The simulator circuitry then generates output signals to the security system controller to simulate pressing of keys on the keypad corresponding to the access code, whereupon if the simulated access code matches one of the security codes stored in the security system controller's memory, the security system will be activated/deactivated as if the access code was manually entered through the keypad.
