SUBJECT:
INCORRECT IGNITION KEY CODE RECORDS
MODELS AFFECTED:
1989 ELDORADOS, SEVILLES, AND ALLANTES
Some 1989 Eldorados, Sevilles, and Allantes may have had improper codes recorded for the vehicle ignition key. This code information appears on the
vehicle invoice and in selected Cadillac data information systems. The original key knock-out tags are marked correctly.
The affected key records will contain the letter "V" or "W" in the THIRD digit of the four-digit code. Key records containing an "A" or "B" in the third
digit or "V" or "W" in the SECOND digit are not affected. The record of the PASS KEY electrical code is also unaffected.
If the key code listed on the factory invoice has a "V" or "W" in the THM position, reverse the second and third digits for the proper key code. For
example, a 12V3 should be 1V23.
Please note that a "V" or "W" in the third digit may be correct for some other model years of Cadillac vehicles. This information pertains only to 1989
Eldorados, Sevilles, and Allantes.
