Auxiliary key for milling

The auxiliary key for milling corrects malfunctions after milling.  

After milling there may some obstacles which the auxiliary key helps to eliminate:

1. On cylinders with emergency function: Maintain the locking engagement pushed inside with the auxiliary key in the middle of the cylinder while turning it.

2. Normal cylinders: Engagement slipped forwards by the vibrations during milling. Keep the cylinder hole vertical and move the engagement inside with the auxiliary key. This allows turning the locking nose.

3. Key in the cylinder from inside: While turning with the auxiliary key, push a sharp 1mm spring steel wire at the border of the cylinder plug so that it takes along the locking nose.
