okay lets set one thing straight i know my radio's anti theft code, the problem that i'm having though is it won't let me enter it in. when i start my car up the display just reads "code" but when i punch my code in nothing happens it still says code. My lights got left on a couple of weeks ago and it hasn't worked since it got jumped?? Any ideas on what the problem may be?

 

Disconnect the battery for a bit. It'll reset the system and then try again. It'll work 4 sure.
