Key locked in the lock cylinder of the French window. Can not close the French window and can not get out the cylinder, the key not wanting to turn. Do you have a solution?

Start with lubricate the lock by injectingdegripante oil in the keyhole. You can also penetrate graphite powder. Often the problem you describe comes from a lack of lubrication at the end of the winter (the difficulty to enter or leave the key of the lock is the harbinger).

If the lock remains locked, you can try to make a hole of 6 mm with a metal drill right under the imprint of the key (the part where one pushes this one). Small brass nipples will then appear. It will be necessary to extract them one by one then to turn the key to open the door. Once this operation is complete you will have to change the cylinder of the lock full.
