A person approaching the outside of the locked vehicle
without an authorized keyless access transmitter,
however, will not be able to open the door, even
with a transmitter in the vehicle. See Keyless Access
System Operation on page 2-8 for more information.
You may temporarily disable the keyless locking feature
by pressing the door unlock switch for three seconds
on an open door. Keyless locking will then remain
disabled until a door lock switch is pressed or until the
power mode transitions from the off power mode.
To select whether the horn sounds or the lights flash
when the vehicle is locked, see "Remote Door Lock"
earlier in this section.

the menu up/down button to scroll through the following
settings:
Off (default): The keyless locking feature will be
disabled.
On: The keyless locking feature will be enabled.
The doors will automatically lock several seconds after
you turn the ignition off, remove a keyless access
transmitter from the interior of the vehicle, and close all
of the doors.
No Change: No change will be made to this feature.
The current setting will remain.
To select a setting, press the set/reset button while the
