Keyless Entry Transmitter: Description and Operation

1999 Ford Taurus V6-3.0L VIN 2 Flex FuelSECTION Description and Operation
NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.

The keyless entry remote transmitter performs the following functions:
- unlocks driver door
- unlocks all doors and liftgate
- releases luggage compartment door
- operates personal security alarm
- arms/disarms anti-theft system
- issues interior lamps on (when unlocking) and off (when locking) commands to the Generic Electronic Module (GEM)

The electronic door lock control system includes two four-button (hand-held) keyless entry remote transmitters. Keyless entry remote transmitters are reprogrammable and all keyless entry remote transmitters for the vehicle must be set at the same time. When troubleshooting the system, one keyless entry remote transmitter is essential to perform tests.

To unlock the driver door:
- Press the unlock button on the key less entry remote transmitter.

This will also disarm the anti-theft system. To unlock all doors and liftgate:
- Press the unlock button on the keyless entry remote transmitter a second time, within five seconds of the first unlock.

NOTE: If more than five seconds have elapsed since the first press of the unlock button, pressing the unlock button again will only unlock the driver door a second time.

To lock all doors and arm the anti-theft system (if equipped):
- press lock button on the keyless entry remote transmitter once.

To confirm that the doors have locked (and that the anti-theft system has armed):
- press lock button again, from one to five seconds after the first press. The horn will chirp once if the doors have been locked and all doors and the liftgate are closed. The horn will chirp twice if one of the doors or liftgate are open.

To activate the personal security alarm:
- press the red panic button on any keyless entry remote transmitter. The horn will beep and the headlamps and exterior lamps will flash for a maximum of two minutes and 45 seconds.
