Dont assume because you may have a piece of dowel or blocking device of some kind that it qualifies as a window lock. If it is not secured by some form of restricted security then it is not locked and can be removed by a thief .
If a thief enters from the roof area which is relatively easy by removing roof tiles , then climbing inside the roof cavity and climbing through the manhole , or simply breaking the plaster ceiling ,he then can simply remove the non blocking device you have in your window track , and if the window is large enough as most do have ,simply pass televisions , computers ect through the window to a fellow thief. A window lock qualifies if it is key locked of some description. Call Arrow locksmiths today to give you a full description of what is required to properly secure your windows.
