Pontiac 2004 GTO - Manual (Page 65)

Remote Keyless Entry System
Operation
The buttons on your key
allow you to lock and
unlock your doors
or unlock your trunk.
When pressing the key buttons, ensure that other keys
on the key ring are not between the main key and
the vehicle. Other keys can obscure the signal being
transmitted to the vehicle.
When a button on the key is pressed, it sends a signal
to the vehicle. The receiver of the signal is a small
rectangle on top of the dashboard, in the center. The
receiver is also used to measure sunlight. It is important
that the receiver is clean, not covered, and that there
are no metal objects close by, as this may block
the signals.
LOCK: Press this button on the key to lock all the
doors, disable the engine, and set the alarm. The
vehicle’s turn signals will briefly flash.
If you prefer to have the turn signals flash accompanied
by the horn sounding, the LOCK feature can be
changed. See Vehicle Personalization on page 2-32.
The LOCK button on the key will not work if the ignition
is turned on or if the driver’s door is open.
UNLOCK: Press this button on the key to unlock the
doors. The turn signals will flash twice, and the horn will
chirp twice, if selected through vehicle personalization.
The interior light will also turn on for a short time. If
UNLOCK is pressed once, the driver’s door will unlock.
If UNLOCK is pressed a second time, or is held
down for more than half a second, all the doors will
unlock. If you prefer to have all the doors unlock with a
single press, the unlock feature can be changed to
unlock all doors. See “Two Stage Unlock” under Vehicle
Personalization on page 2-32.
If the lock system is overloaded as a result of repeated
use in a short time interval, the power supply is cut
off for about 30 seconds. The door lock system
has been designed to make the vehicle horn chirp
rapidly five times if it detects a fault in the lock system
when the LOCK button is pressed. You should check to
see that the doors have locked.
