After disconnecting the battery for over an hour, my '96 Explorer alarm hasn't worked. The key fob works to lock/unlock and the panic button works. Could never figure out how to reset the alarm thinking perhaps the alarm broke.

Just picked up the Explorer from the dealer and the service sheet says the alarm was reset. The service rep said it was reprogrammed.

Does anyone know how to reprogram the alarm? Would like to know how in case I disconnect the battery again.
