Yes you can get a red master from ford, and also at the same time have the old lost keys codes deleted, prices vary hugely I had a mk1 mondy with same problem, cost me around £60 for 1 red master 1 black and the old keys deleted, which I was happy with had a quote from another ford dealer(emg) for around £150 for same work.
Problem is you need to get the car to them in the first place, AA RAC ?
