SENTRY KEY®
The Sentry Key® Immobilizer System prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed
or activated. Operation is automatic, regardless
of whether the vehicle is locked or unlocked.
The system uses a Key Fob with a factory-
mated Remote Keyless Entry (RKE) transmitter,
an Ignition Node Module, Keyless Ignition Node
(KIN) and a RF receiver to prevent unauthor-
ized vehicle operation. Therefore, only Key
Fobs that are programmed to the vehicle can be
used to start and operate the vehicle. The
system will not allow the engine to crank if an
invalid Key Fob is used to start and operate the
vehicle. The system will shut the engine off in
two seconds if an invalid Key Fob is used to
start the engine.
NOTE:
A Key Fob that has not been programmed is
also considered an invalid key.
During normal operation, after turning on the
ignition switch, the Vehicle Security Light will
turn on for three seconds for a bulb check. If the
light remains on after the bulb check, it indicates
that there is a problem with the electronics. In
addition, if the light begins to flash after the bulb
check, it indicates that someone used an invalid
Key Fob to try to start the engine. Either of these
conditions will result in the engine being shut off
after two seconds.
If the Vehicle Security Light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there
is a fault in the electronics. Should this occur,
have the vehicle serviced as soon as possible
by an authorized dealer.
CAUTION!
The Sentry Key® Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
All of the Key Fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
Replacement Keys
NOTE:
Only Key Fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a Key Fob is
programmed to a vehicle, it cannot be pro-
grammed to any other vehicle.
CAUTION!
•
Always remove the Key Fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.
•
For vehicles equipped with Keyless Enter-
N-Go™, always remember to place the
ignition in the OFF position.
At the time of purchase, the original owner is
provided with a four-digit Personal Identification
Number (PIN). Keep the PIN in a secure loca-
tion. This number is required for authorized
dealer replacement of Key Fobs. Duplication of
Key Fobs may be performed at an authorized
dealer. This procedure consists of programming
