replace it My driver's door lock and ignition barrel have both had this problem where it is hard to turn the key, at one point I couldn't turn the key at all and was stuck at 3 in the morning! Anyway, I took the lock out and took it apart. Inside is columns of plates, the lock mechanism. If you gently file the gaps just a small amount at a time and keep trying the key until it works. And it's still working now, 3 years later! If you don't fancy that locks in scrapyards are very cheap, I picked one up for a fiver, just make sure they have the key for it!
