Electrical problem
2002 Buick Century 6 cyl Front Wheel Drive Automatic

The panic alarm on my car keeps going off all by itself, this started happening a day ago. It went off all night last night without any pushing the button on the remote keyless entry. We have disabled the horn for now but you can still see the lights flashing, so it is still going off by itself. What could this be? Someone told me that I should find the valet switch and reset the alarm, is this correct? I can't really afford to take it to the shop right now so any idea's would be appreciated.
Do you

There is no way to disable the alarm on your vehicle? The vehicle will have to be plugged into a computer with the TECH2 software to discover the fault in your RCDLR. You can however personalize your system with the following steps to disable the exterior light operation for the time being?

KEYLESS ENTRY SYSTEM DESCRIPTION AND OPERATION
The keyless entry system is a supplementary vehicle entry device. Use the keyless entry system in conjunction with a door lock key. Radio frequencies or discharged batteries may disable the system.
Keyless entry allows you to operate the following components:
The door locks
The rear compartment lid release
The illuminated entry lamps
The panic alarm (instant alarm)
The keyless entry system has the following main components:
The transmitters
The remote control door lock receiver (RCDLR)
The RCDLR communicates with the body control module (BCM) through the keyless entry serial data circuit. When you press a button on a transmitter, the transmitter sends a signal to the RCDLR. The RCDLR sends a request to the BCM and the BCM performs the appropriate function.
