INFO. ON REMOTE KEYLESS ENTRY (RKE) TRANSMITTER

SUBJECT: INFORMATION ON REMOTE KEYLESS ENTRY (RKE) TRANSMITTER

VEHICLES AFFECTED: ALL 1990-93 MODELS WITH RKE

When an owner returns to the dealership with a Remote Keyless Entry (RKE) transmitter concern on 1990-93 models, it is important to follow the procedure below:

Determine if the batteries are operational. Battery life for each transmitter should be 2 years. There have been some cases where RKE transmitters have been replaced when the only problem was a dead battery. Refer to Section 9K in the Service Manual for proper diagnostic procedures and battery replacement information.

THIS INFORMATION PERTAINS TO 1991-92 "C" AND 1992 "H" MODELS ONLY.

If a customer returns with a broken key ring tab, refer to the GMSPO catalogue to see if there is a replacement back cover available instead of replacing the entire RKE transmitter. (The Eighty-Eight and Ninety-Eight are two Oldsmobile models with replacement covers.)

Some 1991-92 C car and 1992 H car RKE transmitters may operate intermittently or activate the locks without pressing the buttons. If the buttons feel flat, there is a good chance that the mylar under the buttons has shifted on the circuit board. If this condition exists, you will need to replace the transmitter.

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.
