forcible removal of the insert (fabka) from the lock may damage the lock (the lock mechanism itself). if you don't even have a drawer about the construction and function of the liner, call a locksmith - he will exchange the liner for a new one (although a blonde would really be able to insert a new fabric - I know, I did it too). otherwise, you may have to replace the lock, or the fittings or doors if you damage them when removing the old insert.
