Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition,
sounds a signal 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 — IF
EQUIPPED
The Sentry Key Immobilizer System (SKIS) 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. Only
keys 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 SKIS 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 SKIS 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.
