Key-In-Ignition Reminder
If you open the driver’s door and the key is fully inserted
in the ignition switch, a chime will sound to remind you
to remove the key.
SENTRY KEY IMMOBILIZER SYSTEM
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 “Sentry Key/
Security Alarm Indicator Light” (located in the instru-
ment cluster) 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 “Sentry Key/Security Alarm 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.
