1999 Honda Accord Ignition barrel seized

My Accord's ignition suddenly seized.
I can turn the key enough to unlock the steering but only about halfway between Off and the first ignition stage I.

The only options I have been offered are to replace the entire ignition system and get nee keys programmer. The cost of the ignition system is more than $350 alone.

Note I can start the car by removing the ignition wheel with a screw driver as long as the key is in the ignition tinamous the chip to be detected for the immobiliser.

So it would seem that the problem is restricted to the barrel turning and nothing else. However there does not seem to be an easy solution such as being to replace just the lock barrel.

Or is there? Any advice would be much appreciated.

Thanks.
