All Saab cars are equipped with an SID (Saab Information Display) unit that displays various information about the amount of fuel left, the radio station you're listening to and the key's battery status. It is time to change your key batteries if the key stops working or responds slower than usual. The SID on your car will also say "Replace Key Battery." Saab keys use either a CR 2032 or a CR 1632 battery depending on key type. There are two types of keys. The first generation key has one key and a transponder and the second generation key is a one piece key with a built in transponder.
