Pontiac 2005 GTO - Manual (Page 63)

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 centered on top of the dashboard.
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 2-30.
The LOCK button on the key will not work if the ignition
is turned on, or if the driver’s and/or passenger’s
door is open.
Prior to locking your vehicle, make sure all the doors are
closed completely. If the LOCK button is pressed when a
door is open, the horn will sound three times to indicate
that a door has not locked. Close the open door and reset
the remote system by first pressing the UNLOCK button
and then the LOCK button on the key.
