Recently I had my radio locked and I just put the code back in and now only my driver door speakers work. Anything I can do to fix it? Sorry if i'm a new driver.

 

Why was the radio locked? If you removed the radio or did some work inside the dashboard, I'll guess that the speaker-wire is loose or disconnected for those speakers.

Otherwise, more troubleshooting. The security code for the radio just locks out the entire radio. It doesn't operate individually on any speaker circuits.
