# Pressing any Button on Saturn RKE Fob, Sets Off Alarms on Some Automotive Security Systems

Subject: | Pressing Any Button on Saturn RKE Fob, Sets Off Alarms on Some Automotive Security Systems -- Security System Needs to be Reprogrammed.

Models: | 1996 Saturns equipped with optional remote keyless entry (RKE) system

### Condition:

When customers use their RKE system hand-held transmitter (Fob) to operate the RKE system, it may cause a security system, installed on another vehicle in the vicinity of their vehicle, to trigger an alarm.

### Cause:

Some automotive security systems can accept 4 transmitter codes. When less than 4 transmitter codes are programmed, dummy-codes are used to fill the empty transmitter code locations. These dummy-codes match the wake-up message transmitted by the Saturn RKE system hand-held transmitter when any button is pressed. When the security system receives this message, it may interpret the message as a panic alarm, and sound the siren and flash the lights of the vehicle in which it is installed.

### Correction:

To eliminate this condition, the affected security system must have 4 transmitter codes programmed into the controller. Each time a hand-held transmitter is programmed into the controller it takes up one of the memory locations. one hand-held transmitter can be used to fill all 4 memory locations, or multiple hand-held transmitters can be used to fill all 4 memory locations: as long as all 4 memory locations, in the security system controller are filled.

If the security system on the other vehicle is manufactured by Code-Alarm®, and assistance is required, call the Code-Alarm® service number, 1-800-421-3209. If the security system on the other vehicle is a Goodwrench system, call 1-800-GM-Tech1 (1-800-468=3241) for assistance.
