Honda ignition locks frequently seem to stop working. Read the follwoing to see if this is the issue you are having and how to fix the problem:
Either you can put the key all the way in the ignition lock, but it will not turn or you can only insert the key halfway, and not all the way.

Problem 1-You can insert the key all the way, but it will not turn.
Solution-Have a new key by code cut to see if it solves the problem, or replace the ignition lock.

Problem 2-One of the wafers in the lock is hanging up, not allowing full insertion of the key.
Solution-Replace the ignition with a new one. Having it repaired is only a temporary solution, and the rest of the wafers will then fail one by one in a very short time.
