Immobiliser Operation - Cadillac CTS 2013 Owner's Manual

If the engine still does not start and
the key appears to be undamaged
or the light continues to stay on, try
another key.
If the engine still does not start with
the other key, the vehicle needs
service. If the vehicle does start, the
first key may be damaged. See your
dealer who can service the
theft-deterrent system and have a
new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys can
be programmed for the vehicle. The
following procedure is for
programming additional keys only.
To program a new key:
1. Verify that the new key has
stamped on it.
2. Insert the current key in the
ignition and start the engine.
If the engine will not start, see
your dealer for service.
3. After the engine has started, turn
the key to LOCK/OFF, and
remove the key.
4. Insert the key to be programmed
and turn it to ON/RUN within
five seconds of the ignition being
turned to LOCK/OFF in Step 3.
5. The security light will turn off
once the key has been
programmed. It may not be
apparent that the security light
went on due to how quickly the
key is programmed.
6. Repeat Steps 1 through 4 if
additional keys are to be
programmed.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
