Cadillac CTS/CTS-V Owner Manual - 2011
2-26 Keys, Doors and Windows
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 ignition
control knob is turned to LOCK/OFF.
The immobilization system is
disarmed when the ignition control
knob is pushed in and a valid
transmitter is found in the vehicle.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.
The system has one or more
keyless access transmitters that are
matched to an immobilizer control
unit in your vehicle. Only a correctly
matched keyless access transmitter
will start the vehicle. If the keyless
access transmitter is ever damaged,
you may not be able to start your
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
ignition control knob off and try
again.
If the ignition control knob does not
rotate, and the keyless access
transmitter appears to be
undamaged, try another keyless
access transmitter. Or, you may try
placing the transmitter in the
transmitter pocket located in the
center console. See “Electronic Key
Not Detected” under Key and Lock
Messages on page 5‑36.
If the ignition control knob still does
not rotate with the other transmitter,
the vehicle needs service. If the
ignition control knob does rotate, the
first transmitter may be faulty. See
your dealer who can service the
theft-deterrent system and have a
new keyless access transmitter
programmed to the vehicle.
It is possible for the immobilizer
system to learn new or replacement
keyless access transmitters. Up to
4 keyless access transmitters can
be programmed for the vehicle. To
program additional transmitters, see
“Programming Transmitters to the
Vehicle” for Keyless Access under
Remote Keyless Entry (RKE)
System Operation (Key Access)
on
page 2‑5
or Remote Keyless Entry
(RKE) System Operation (Keyless
Access) on page 2‑7.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
