Radio gone dead in my Ford Focus?

If your cd or cassette player are also not running, make sure connections on back of "detachable security key" are clean. If required gently "scrape" electrical connections to ensure good electrical contact. Ensure "key" is firmly sitted / clicked back into head unit. If your cd or cassette player are running, then its not the "key".
Best of luck to you.
