I have 25 year old Anglian double glazing. On one bedroom window, I
can insert and withdraw the key, but the key won't turn in the lock to
lock the window. As my 2 year old grandson is staying with us
overnight this weekend, and he's into everything that can be turned /
switched / opened, I've very keen to lock the window. I've been
squirting wd40 into the lock all day, but it's just the same. Can
anyone suggest what else do do?
TIA,
FC
