INFO. ON LOCK CYLINDER CODING

SUBJECT: Service Information on Lock Cylinder Coding -------------------------------------------

MODELS AFFECTED: 1991-1995 Saturns -----------------

PURPOSE: Due to a design change in the 1995 ignition lock cylinder, the Saturn key code book supplied by Ilco-Unican for Saturn Retailers as a part of the key cutting equipment has been revised. In 1991 - 1994 vehicles, the ignition lock cylinder uses tumbler positions 1 through 6. In 1995 vehicles, the ignition lock cylinder uses tumbler positions 1 through 7.

NOTE: 1995 vehicle ignition locks require new service part numbers. Refer to chart on the following page for part usages.

In addition, some Saturn key code books supplied to recently opened Retailers have been misprinted in the door code column. The door lock cylinders for 1991-1995 vehicles use tumbler positions 2 through 6. These key code books incorrectly indicate positions 1 through 5 for the door lock cylinder. If any lock cylinder is assembled using the incorrect tumbler positions, the key will not function in the lock.

A revised Saturn key code book for 1991-1995 vehicles is included with this mailing. Please distribute this Saturn key code book to the appropriate person and discard the Saturn key code book you currently have in your retail facility. This will prevent any possibility of the incorrect Saturn key code book being used.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
