# SI Regarding New Ignition Lock Cylinder Design and New Key Codes for Ignition Lock Cylinder and Key Cuts

Subject: | Service Information Regarding New Ignition Lock Cylinder Design and New Key Codes for Ignition Lock Cylinder and Key Cuts

Models: | 2002 Saturn L-Series vehicles

### Purpose

The purpose of this bulletin is to provide service information regarding the introduction of new "O" key codes and a new 7 tumbler design ignition lock cylinder rather than the 9 tumbler design previously used.

The 7 tumbler ignition lock cylinder will service all 2000 - 2001 L-Series vehicles.

The new key codes can be found in the "L-Series Key Code Supplement". * In the supplement you will find:

• | A new key code listing beginning with the prefix "O".

• | A 7 tumbler conversion for each key code including all "H" and "O" key codes.

Important: Always use the 9 digit code for key cuts whether the lock cylinder is a 7 or 9 tumbler system.

Key Coding for the "Door/Rear CMPT" and "I/P CMPT" are unchanged.

Important: The following chart is only an example. Do not use this key code on an actual repair to code cylinders or cut keys.

Code # | Ignition with 9 Tumblers | Ignition with 7 Tumblers | Door/Rear CMPT | I/P CMPT
--- | --- | --- | --- | ---
O1795 | 342112422 | 3212422 | 112422 | 2422
