Sometimes, these type of handle locks fail and it's due to the soft metal used by the manufacturers. The material used for manufacturing this type of handle is alloy. Unfortunately, you can not glue or weld alloy parts and the ultimate solution is to replace the part with a new one. But, do not panic, 112 handymen will teach you how to do it yourself.

Tools required:

Removing old lock

First thing first: Close the window and put the handle in the open position, remove the screw that will be covered by the handle when the handle is in close position.
