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 Cus-
tomer Key Programming procedure. This procedure con-
sists of programming a blank key to the vehicle electron-
ics. A blank key is one which has never been programmed.
NOTE: When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.

Customer Key Programming

You can program new keys to the system if you have two
valid keys by doing the following:
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 and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chime
will sound and the SKIM indicator light will begin to
flash. Turn the ignition switch OFF and remove the
second key.
