Keyless Entry (RKE) System
Operation (Key Access) 032.
Do not leave the key or device that
disarms or deactivates the vehicle
theft system in the vehicle.
See your dealer to get a new key
blank cut exactly as the ignition key
that operates the system.
Immobilizer Operation
(Keyless Access)
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off. The immobilization system is
disarmed when the ignition button is
pressed in and a valid transmitter is
found in the vehicle.
The security light in the instrument
cluster comes on if there is a
problem with arming or disarming
the theft-deterrent system.
The system has one or more
transmitters matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start the
vehicle.
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
vehicle off and try again.
If the RKE transmitter appears to be
undamaged, try another transmitter
or place the transmitter in the
transmitter pocket/insert next to the
center console storage area
between the driver and front
passenger seats. See
“Starting the
Vehicle with a Low Transmitter”
under Remote Keyless Entry (RKE)
System Operation (Keyless Access)
0 34 orRemote Keyless Entry
(RKE) System Operation (Key
Access) 032.
If the engine does not start with the
other transmitter or when the
transmitter is in the pocket in the
center console, the vehicle needs
service. See your dealer who can
service the theft-deterrent system
and have a new transmitter
programmed to the vehicle.
Do not leave the transmitter or
device that disarms or deactivates
the theft-deterrent system in the
vehicle.
