Stop fumbling through pockets and handbags for keys and remote controls. The ECKey EK2 Virtual Keypad allows you to use a Bluetooth-Enabled phone or PDA as a key to lock and unlock almost any electronically controlled access control device such as a door lock, gate, alarm or garage door. The ECKey is a Bluetooth based electronic relay unit that installs next to your electronic lock. By leaving your phones Bluetooth setting in Discovery mode, the ECKey will detect your phone when you walk into range (which is adjustable from three feet to 30 feet). When the presence of your phone is detected, the ECKey will send a message requiring your PIN number for authentication and upon confirmation it will unlock the door, open the gate or disable your alarm. An unlimited number of Bluetooth-enabled devices can be registered, so it will work for the whole family. No software is required on the phone or PC. The ECKey EK2 Bluetooth-enabled Virtual Keypad Access Control System does NOT come with a power supply. The power is drawn from the same source as the electric door strike/gate or mag lock, each sold separately, that it is being used for. Please refer to the wiring diagram. For a similar, "hands free" solution that requires no PIN number, take a look at the ECKey EK3 Professional Relay Unit; it will unlock almost any relay based electronic device when your Bluetooth-enabled phone is in range. Access Control The most common application for the ECKey EK2 Virtual keypad is as an access control system for door locks. The ECKey relay unit wires to an electric door strike (and other similar door strikes), which will be triggered to open upon entering your PIN number for authentication. The lock will remain open for three seconds after which it will return to a normally locked state.
