SUBJECT:
Service Manual Procedures for New Lock System for Interim 1997 Saturns

MODELS AFFECTED:
1997 Saturns





PURPOSE:
Saturn interim 1997 vehicles will be manufactured with a new lock system for the ignition, door and rear compartment/liftgate locks. (This new lock system will be referred to as second design and the previous lock system will be identified as first design.) To help identify if a vehicle is equipped with a first or second design lock system, check the key. The new second design lock system has a different shaped key than the key used in the first design lock system (refer to the illustrations).

Refer to this bulletin for new general information and coding procedures for the new second design lock system.





GENERAL INFORMATION

Key Identification and Usage
The second design lock system is a one key system with a key profile that has a two-sided cut, and milled grooves that are unique to the Saturn lock system. The number of tumblers in the ignition cylinder has increased from seven to nine.

Cutting Keys
The Saturn approved key cutting tool requires adapter kit SA9703B to cut the second design keys. The adapter kit consists of a depth knob, spacing plate, key insert, and punch and die assembly. To install adapter kit to key cutting tool, follow steps in instruction manual provided with key cutting tool. The spacing plate provided with the adapter kit accommodates positions 1 through 10. The Saturn key uses positions 2 through 10.

IMPORTANT:
First design keys cannot be cut with the adapter kit.

The customer information card or the retailer records will show the key code as a four-digit numeric code. To determine the actual cut sequence of the key from this code, look up the code in the "1991-1997 Saturn Key Code Manual" and the cut sequence will be shown to the right of the code listing. The master cut sequence should be used to cut new keys, as it has all of the cuts necessary for the key to work properly in all the locks on the vehicle.

Determining the Key Code

1. Insert the key in the Saturn approved key cutting tool with the tip of the key against the stop.

2. With the cutting die in the down position, move the carriage toward the die until it bottoms out, and record the depth (1, 2, 3 or 4).

3. Repeat for each cut position, 2 through 10. Positions are read from key head to key tip.
