If a damaged or wrong key has
been used, the system will not
allow the engine to start. If the
engine does not start and the
Security System Light comes on,
there may be a problem with this
system.
A text message may also appear in
the Driver Information Center
display.
See the following under "Driver
Information Center Messages" in
Section 1 for more information:
• SERVICE THEFT DETERRENT
SYSTEM (service theft deter-
rent system)
Turn the ignition off and try again.
If the engine still does not start and
the key appears to be undamaged,
try another ignition key. You may
also want to check the fuse. See
"Fuses and Circuit Breakers" for
more information. If the engine
still does not start, have the vehicle
serviced. If the engine does start,
the first key may be faulty. See
your dealer to have a new key
made.
Do not leave the key or the device
that disarms the theft deterrent
system in the vehicle.
Modifications made to this
system by anyone other than an
authorized service facility may void
authorization to use the system.
Section 3
PROGRAMMING ADDITIONAL
KEYS
Any new key must be
programmed before it will start
your vehicle.
Additional keys can be obtained
from an authorized dealer.
The replacement key must have a
transponder embedded in it.
If a key is lost or damaged, but you
still have one key that operates
the vehicle, you can program
additional keys. A maximum of
10 keys can be programmed to
the vehicle.
To program an additional key:
1. Verify that the new key has
stamped on it.
2. Start the engine using the pre-
viously programmed master
key.
If the engine does not start,
see your dealer for service.
