2-24 Keys, Doors, and Windows
If the vehicle does not have keyless
access, use either the removable
key or the Remote Keyless Entry
(RKE) transmitter to lock or unlock
the doors and operate the deadbolt.
Hold the removable key in the
lock position for a few second or
quickly turn the key twice in the

with the deadbolt.
Press on the RKE transmitter
once to lock all the doors.
Pressing the button again within
three seconds will secure the
deadbolt.
When the doors are secured with
the deadbolt, the manual door lock
controls will not unlock the doors.
Also, if the theft-deterrent system is
armed, the doors cannot be
unlocked using the power door lock
controls.
Press on the transmitter once to
open the deadbolt and unlock the
driver door. Pressing the button
again within three seconds will
unlock all the doors.
If the vehicle does not have keyless
access, unlocking the driver door
from the outside with the removable

doors. However, only the driver door
will be unlocked.
You must unlock the passenger
doors manually or with the power
door locks.

Immobiliser Operation

(Key Access)
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilised when the key is
removed from the ignition.
The system is automatically
disarmed when the vehicle is
started with the correct key. The key
uses a transponder that matches an
immobiliser control unit in the
vehicle and automatically disarms
the system. The vehicle may not
start if the key is damaged.
The security light in the instrument
cluster, comes on if there is a
problem with arming or disarming
the theft-deterrent system.
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
