BULLETIN NO.: 99-T-O1ISSUE DATE: January, 1999
GROUP/SEQ. NO.: Body-01
CORPORATION NO.: 99-08-52-001
SUBJECT:
Service Information for New 1991-1997 First Design Key (Square Head) Ignition Lock Cylinders.
This Bulletin Updates the Ignition Lock Cylinder Coding Procedure in the 98-99 Body Repair Service Manual.
MODELS AFFECTED:
1991-1996 and 1997 interim Saturns with first design key (square head)
PURPOSE:
Due to a design change in the service replacement parts for 1991-1996 and 1997 first design key (square head) ignition lock cylinders, the ignition lock cylinder packages, ignition lock cylinder component parts, and the 1991-1999 Saturn Key Code Manual need to be updated.
All 1991-1997 first design key (square head) service replacement ignition lock cylinders will now have a sidebar and six tumblers. The sidebar is not serviced separately. The tumblers, tumbler springs, bezel, ignition pin, and ignition pin spring are all unique to the new design and are used only for service replacement of 1991-1997 first design key (square head) ignition lock cylinders-not for 1998-1999 Saturns.
IMPORTANT:
All first design key (square head) ignition lock cylinders in need of repair or coding should be serviced with second design service replacement ignition lock cylinder packages (refer to parts list) and coded using second design ignition lock cylinder component parts.
In addition, the 1991-1999 Saturn Key Code Manual must be updated to reflect the change to a 6-tumbler ignition lock cylinder design. Please make the following column heading changes in the "1991-1997 Saturn Key Code List" section of the 1991-1999 Saturn Key Code Manual:
Also, cut two new keys (P/N 21097940) for all customers using the "MASTER KEY" code. Some customers with 1991-1994 vehicles may have the shorter version of the first design key (P/N 21097305) which will rub on the bezel of the 1991-1994 second design ignition lock cylinder. (Reference Technical Bulletin 94-T-50 for key length change) After cutting new keys, scrape off any burrs and perform a functional check of all vehicle lock cylinders with new keys.
The following pages provide the ignition lock cylinder coding procedure. Copies of this bulletin should be made and inserted in the "General Information" section of all 98-99 Body Repair Service Manuals before the "Ignition Lock Cylinder Coding-All" procedure.
