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 is physically held
against the ignition key being 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.
