door, turn the key rearward, to unlock the door, turn the

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 switch 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 that
someone 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:
²The Sentry Key Immobilizer System is not compatible
with some after-market remote starting systems. Use
of these systems may result in vehicle starting prob-
lems and loss of security protection.
²Exxon/Mobil Speed Pass,Ÿ additional Sentry Keys, or
any other transponder-equipped components on the
same key chain willnotcause a key-related (transpon-
der) fault unless the additional part isphysically 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.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!
Always remove Sentry Keys from the vehicle and
lock all doors when leaving the vehicle unattended.
At the time of purchase, the original owner is provided
with a four-digit PIN number. Keep the PIN in a secure
location. 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 Pro-
gramming procedure. This procedure consists of pro-
gramming 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. Turn
the ignition switch to the ªONº position for at least 3
seconds, but no longer than 15-seconds. Then, turn the
ignition switch to the ªLOCKº position and remove the
first key.
3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ªONº position within 15
seconds. After ten seconds, a chime will sound. In
addition, the Vehicle Security Alarm Indicator Light will
begin to flash. Turn the ignition switch to the ªLOCKº
position and remove the second key.
