Keys, Doors, and Windows
The vehicle is automatically
immobilized when the transmitter
leaves the vehicle.
The immobilization system is
disarmed when the ignition is turned
on or in ACC/ACCESSORY and a
valid Remote Keyless Entry (RKE)
transmitter is 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 RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched
RKE transmitter will start the
vehicle. If the transmitter is ever
damaged, you may not be able to
start your vehicle.
When trying to start the vehicle, the
security light may come 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.
If the ignition will not change from
off to on or ACC/ACCESSORY, and
the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the cupholder in the
center console. See
Keyless Entry (RKE) System
Operation
.
If the ignition mode will not change
with the other transmitter, or with the
transmitter in the cupholder, your
vehicle needs service. If the ignition
does change modes, the first
transmitter may be faulty. See your
dealer who can service the
theft-deterrent system and have a
new RKE transmitter programmed to
the vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed to
the vehicle. To program additional
transmitters, see
“
Programming
Transmitters to the Vehicle
”
under
Remote Keyless Entry (RKE)
System Operation
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.
