Security/theft Code For Nakamichi

[yoichisoma]

Hi

I recently purchased a 95 LS400. The Lexus dealer told me that the Nakamichi unit is relatively new out of another vehicle. It works great. I am having the engine ecu rebuilt and was advised that I may need the security code if the ecu was replaced or battery was removed. I have no manuals and the owner's manual doesn't mention it. How do I figure the code out? How do I set it to what I want? Do I even need to be concerned? I recently removed the battery, and the code was not necessary.

thanks
