If you disconnect the battery for about 1 minute, your radio anti-theft (if you have this feature) should kick in. And the next time you turn on your radio - it will ask you for the radio code.But be warned - if you don't have the code, your radio is gone. You will have to go to your dealer to have it set.===Since your car is new and possibly under warranty, you should get the code for your car (free) and write it down somewhere (like on your registration card). Once your warranty runs out they may charge you for it.
