To install, follow the removal steps in the reverse order,
noting the following points.
1. For the anti-theft system, install the push rod(1) of the

so that there is not continuity between the key switch
side connector terminals No. G5–2 and G5–4 as
shown in the figure.

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
730RS010
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.
Front Door Lock Actuator Removal

procedure in this section.

Anti-theft System
General Description
The circuit consists of the starter switch, anti-theft &
keyless entry control unit, anti-theft horn, front door and
tailgate key switch (detect and tamper switch), door lock
(& power window) switch, door lock actuator for each
door, engine hood switch, clutch start switch (M/T),
ANTI-THEFT indicator light and mode switch (A/T).
The system operates as follows: After locking the starter
switch and removing the starter key (this sets the alarm),
if the door is unlocked in any way other than with the
proper key, the headlights start flashing, the horn sounds,
and the starter circuit is disabled. (However, the engine
hood and all the doors must be locked and closed.)
Once the system has been placed in the warning or alarm
condition, it can be released only when the starter switch
is shifted from “OFF” to “ACC” by the starter key, or when
the lock of the front door or the tailgate is released (to
activate the detect switch) by the starter key.
