Did some checking,I hope you have a key for the lock.It needs to be in the locked position.Just back from the the face you should see a little window and some spring loaded flat tumblers in side.The very front tumbler should be a diff color,maybe a steel color but not brass like the rest(5 of those).Push the front tumbler down,which is actually a retainer that holds the lock plug in.The plug,front face,should come out.Let me know if ya have any problems.8)
