SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized 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 ignition keys, which have an embedded
electronic chip (transponder), to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two (2)
seconds if someone uses an invalid key to start the
engine.
NOTE:A key, which has not been programmed, is also
considered an invalid key even if it is cut to fit the
ignition lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Alarm Indicator Light will
turn on for three (3) 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 thatsomeone used an invalid key to start the engine. Either of
these conditions will result in the engine being shut off
after two (2) seconds.
If the Vehicle Security Alarm Indicator 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 ser-
viced as soon as possible.
NOTE:

The Sentry Key Immobilizer System is not compatible
with remote starting systems. Use of these systems
may result in vehicle starting problems and loss of
security protection.
•Exxon/Mobil Speed Pass,™ additional Sentry Keys, or
any other transponder-equipped components on the
same key chain willnot
cause a key-related (tran-
sponder) fault unless the additional part isphysi-
cally held against the ignition keybeing used
when starting the vehicle. Cell phones, pagers, or
other RF electronics will not cause interference with
this system.

All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:
Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.
At the time of purchase, the original owner is provided
with a four-digit PIN number. This number is required
for dealer replacement of keys. Duplication of keys may
be performed at an authorized dealer or by using the
Customer Key Programming procedure. This procedure
consists of programming a blank key to the vehicle
electronics. A blank key is one, which has never been
programmed.
NOTE:When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to the
dealer.
Customer Key Programming
If you have two valid sentry keys, you can program new
sentry keys to the system by performing the following
procedure:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chime
will sound and the Vehicle Security Alarm Indicator
Light will begin to flash. Turn the ignition switch OFF
and remove the second key.
4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound and the Vehicle
Security Alarm Indicator Light will stop flashing, turn on
again for 3 seconds, and then turn off.
