Do PVC Window Handles Really Need Key Locks?

No matter which brand of PVC window you choose to opt for,  and no matter who is fabricating the windows whether it be a mass producer or a small outfit who operates locally chances are that there will be key locks on the handles.

With all the greatest intentions of breaking into a modern second generation windows sash it would be very difficult to achieve, if not impossible.

As long as it is a high specification window and it incorporates a composite multipoint locking mechanism using a combination of roller cams and shoot bolts , once located and fully closed down it is not able to be manipulated. In fact it is virtually impossible to even gain a view of the locking points to start attempting a break in.

The fact is that most people don't actually use them through either giving up trying to find the keys all the time or the fact that they don't want to have a panic when trying to escape in the  event of a fire.

So why the key locks ?


Peace of mind or insurance purposes.?


Many customers and secure minded home owners like the peace of mind that the handle is locked and that they have done everything possible within their simple day to day routine of securing their home.

The reality is that the handle locks are usually the first part of the handle to give way. 

The idea of a push button to open the window handle and an automatic click of the button to indicate a locked window replaces the old opposite style of pushing to lock when closed.

Ultimately these replaced the old cock spur handles on the very early PVC windows in the late 80's early 90's.

Some thoughts are that they will get a reduction in home insurance because they state to the windows have locks on them. 

But this came around first when old timber windows were very easy to break in to and added security bolts and key locks were introduced.

Insurance companies now class the majority of windows to have a secure multipoint locking systems as the majority of windows have been upgraded somehow since the the late 80's even in aluminium windows.So where is the benefit ? some rare insurance policies may mention it brings a small discount but the size is minimal.

There is an argument for someone breaking the glass of a sash and pulling the handle open, but breaking glass on windows isn't a method burglars prefer these days as DNA and threads off clothing is evidence. And with it being a very noisy technique and difficult to break a double glazed unit without causing cuts due to its construction and the way in which they are held and stuck together.

It just seems a bit strange that the part of the window handle that gives up first and the part that is not necessarily covered for 10 years is still incorporated into the window. Most manufacturers only giving 12 months as standard. Is this a service call out for replacements we really need considering the amount of window handles being installed ?

If it doesn't add security value or financial benefits or even an operational advantage in using them, why do we still have them ?
