Remote Keyless/Illuminated Entry System (http://www.fordvehicles.com/help/glossary/index.asp
A feature allowing the owner access to the vehicle interior without using a conventional key by using either a push-button (keypad) panel or remote transmitter as described below:
Push-button Panel Entering a code into the driver’s door push-button panel automatically unlocks the door. The code sequence is programmed at the factory, and owners also can program their own sequence. This feature is available on certain Taurus, Crown Victoria, Explorer and Expedition models.
Remote Transmitter Certain vehicles use a remote transmitter in addition to, or in place of, the door-mounted keypad.
A remote, handheld transmitter is used to operate the vehicle’s electronic entry function:
The transmitter may be used in place of the door-mounted keypad to lock or unlock one or all doors, or open the decklid
On some models, a PANIC button, activated within 33 feet of the vehicle, flashes the lights and chirps the horn as a warning
See specific vehicle sections for application
A conventional key still may be used to unlock the doors whenever desired. See the vehicle sections for remote transmitter functions and availability. The Illuminated Entry System provides added convenience and security when entering the vehicle in darkness:
On some models, the system is turned on by lifting either front door handle
On some models, it generates a ring of light around each front door lock cylinder for easy key insertion
The system also activates all interior courtesy lights to allow a view of the interior before entering The lights stay on for approximately 20 seconds or until the ignition switch is turned on (time delay varies from model to model).
