Key-In-Ignition Reminder
If the driver’s door is opened when the key is in the
ignition and not turned to the ON position, a chime will
sound to remind you to remove the key.
CAUTION!
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIM) prevents
unauthorized operation of the vehicle by disabling the
engine. The system will shut the engine down after 2
seconds of running if an invalid key is used to start the
vehicle. This system utilizes ignition keys which have an
electronic chip (transponder) embedded into them. Onlykeys that have been programmed to the vehicle can be
used to start and operate the vehicle for longer than the
2 second validation time period.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the SKIM indicator
light will come on for 3 seconds immediately after the
ignition switch is turned on for a bulb check. Afterwards,
if the bulb remains on, this indicates a malfunction in the
electronics. If the bulb begins to flash immediately after
the ignition switch is turned on, this indicates that an
invalid key is being used to start the vehicle. Both of
these conditions will result in the engine being shut
down after 2 seconds of running. Keep in mind that a key
which has not been programmed is also considered an
invalid key even if it is cut to fit the ignition for that
vehicle.

If the SKIM indicator light comes on during normal
vehicle operation (it has been running for longer than 10
seconds) a fault has been detected in the electronics and
the vehicle should be serviced 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.
•Mobil Speedpass™, additional Sentry Keys, or any
other transponder equipped components on the same
keychain will not cause a key-related (Transponder)
fault unless the additional part isphysically held
against the ignition keybeing used when starting the
vehicle. Also, cell phones, pagers, or other RF electron-
ics will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Important Note About Service
A four digit PIN number is needed to service the Sentry
Key Immobilizer System. This number can be obtained
from your authorized dealer. However, this number can
also be found on your customer invoice that you were
given upon receipt of your vehicle.
Replacement Keys
NOTE:Only keys that have been programmed to the
vehicle electronics can be used to start the vehicle. Once
a Sentry Key has been 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
