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 THIRD position, reverse the second and third digits for the proper key code. For example, a 12V3 should be lV23.
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.
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.
