Actually, looking in the manual (duh) it says that when the audio system is disconnected from the battery the theft deterrent system activates and a security code must be entered to operate the radio. However, I bought the car used and don't remember receiving a card with the security code stamped on it. Also, I have replaced the battery and did not need to enter a code at that time. And I have disconnected the battery before for several other repairs and have never seen this code required.

Does anyone know where I can retrieve the code?
