Just bought 2004 TL from co-worker. I could not enter correct Security Code when prompted. The seller did not know the code either. Now I just get LOCKED when I hit the talk button and do not have the code. I am confused on NAVI, (this car does not have it), vs radio code vs security code. Acura site refers to "Device Code". There is no device. I started by selecting "Security, New Password, and then I was prompted for the old Security Password/Code. Help appreciated..
