Key Coding

Legend

(1) Key(Actual Size)
(2) Key Code Tag

(3) Position
(4) Level

One key is used for the ignition, door, and tailgate lock
cylinders. The keys are cut on both edges to make them
reversible.
Key identification is obtained from the five character key
code stamped on the key code tag.  From this key code,
the key code cutting combination can be determined from
a code list (available to owners of key cutting equipment
from suppliers).
If key codes are not available from records or tags, the
key code can be obtained from the right hand door lock
cylinder (if lock has not been replaced).  Lock cylinders
supplied by the factory as service parts are unmarked.
If the original key is available, the key code cutting
combination can be determined by laying the key on the
diagram shown in the figure.

Key Styles

Legend

(1) Blank Key Style “A”
(2) Blank Key Style “B”

The keys come in styles A or B depending on the key code
cutting combination.  When the first position in the
combination is a 1, 2 or 3, Style A is used.  When the first
position is a 4, Style B (factory pre-cut key) is used.

Power Door Lock System

General Description

The circuit consists of the door lock (& power window)
switch, door lock actuator for the front and rear door,
tailgate lock actuator and the door lock key switch.  The
front door lock switch –LH is always provided with battery
voltage.
The key or the inside lock button on the both driver’s and
the front passenger’s door can activate the lock
mechanism of all the doors (including the tailgate).
When the driver’s door lock switch or the front
passenger’s door lock switch is turned on, current flows
for about one second to the door lock actuator of each
door connected in parallel with the front door lock (&
power window) switch –LH to activate the actuator to lock
and unlock the doors.
