Audiovox Prestige APS-255 -Accord&Celica

I have two cars, an Accord and a Celica. I have an Audiovox Prestige APS-255 alarm in both cars. I was wondering how I would be able to use the multiple car capabilties with the one remote.K-Dog

what you can do is program one button for each car. If you have a toggle switch for the valet. It is probably the same if you have a push button for the valet thoug. Make sure the car is not in valet mode. Turn the ignition on flip the switch on off three times and the siren should chirp. Press the first button and the siren should sound again. Turn the ignition off and check to see if the button works. If it does do the same thing on the other car with the other button.
