About the Ford 4500 RDS EON

The 4500 RDS EON is the cassette radio fitted to many Ford Fiesta, Focus Mk1, Ka, Transit and Transit Connect models from the late 1990s to the mid 2000s. Like all Ford factory radios it locks after a power loss and asks for a 4-digit code.

Unlike the 6000 CD, the 4500 RDS shows its serial with buttons 2 and 6. The serial always starts with M followed by 6 digits.

Typical problems

  • "10 LOCKED" on the display: too many wrong codes. Leave the radio switched on with the ignition on until the timer clears before trying again.
  • The display shows "---- " instead of CODE: wait with the radio on; the radio is in a waiting period after wrong attempts.
  • The code from the old card does not work: the radio may have been replaced. Always use the serial of the radio in the car.

I tried this site and it worked 100% correctly on my radio! Ford dealer told me he also can provide for free visiting them, but having the option to receive the code via Internet, with a fast response time is ideal. Thank you so much for such a great service!
