Pressing Any Button On RKE Fob Sets Off Alarms On Some Aftermarket Auto Security Systems

Models:
1996 Chevrolet Camaro
1996 Pontiac Firebird

When some owners use their Remote Keyless Entry (RKE) system transmitter (Fob) to operate the RKE system, it may cause an aftermarket security system, either installed on their vehicle or another vehicle in the vicinity, to trigger an alarm.

Some aftermarket automotive security systems can accept four transmitter codes. When less than four 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 RKE transmitter when any button is pressed. When the security system receives the 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.

To eliminate this condition, the affected security system must have four transmitter codes programmed into the controller. No correction is needed to the RKE system. Each time a transmitter is programmed into the controller, it takes up one of the memory locations. One transmitter can be used to fill all four memory locations, or multiple transmitters can be used to fill all four memory locations. As long as all four memory locations in the security system controller are filled, the condition will not recur.

If the security system is manufactured by Code-Alarm(R), and assistance is required, call the Code-Alarm(R) service number, 1-800-421-3209. If the security system is a Goodwrench system, call 1-800-GM-TECH1 (1-800-468-3241) for assistance.
