1994 Ford Taurus Alarm System?

My cousin disconnected the battery before installing a new windshield wiper switch, just to be on the safe side with possible airbag deployment. When he reconnected the battery and tried to start the vehicle, a red indicator light next to the AC vent on the driver's side started flashing, as did the park lights on the vehicle, and the motor would not turn over at all. Is there a way to reset this? My windshield wipers work great now. But I can't get out of the driveway!

Thanks for your help.
