    Purpose of key locking on windows?

    Purpose of key locking on windows? 18th Aug 15 at 9:57 PM
    I was wondering what is the purpose of key locking on house windows?

    Once the handle of a window is pushed into the correct position the window is closed and cannot (in theory) be opened from the outside.

    But some/many window handles also have a key to lock them internally. Is this to stop someone from getting out, or what is the point of the inside key lock?

    There isn't much point. A window handle lock of mine broke once and jammed in the locked position covering the screw. Easy to fix. Force it open and it will break. Then replace with a new handle.

    what happens if you have children or don't you mind them opening the windows & falling out ?

    I think it's so that if someone breaks the window from outside they then can't (Easily) just undo the handle, open the window fully and brush away any glass to give themselves a larger, less sharp opening to climb in through.

    It also lets you lock the window slightly open in most cases.

    And as southcoastgi says it means you can prevent little ones from opening the window.

    You may well find your Insurance Company require you to lock with that key when the property is empty. Read your Policy Document.

    So it won't help on safety, but for insurance purposes it's unlikey to make much difference. I've never investigated any 'empty property' clauses though.

    I suspect a picky insurance company in the event of a claim may well point to the quite reasonable assumption that the locks were in full working order (IE they locked) when you ticked yes on the quote.
    Obviously for locks to work as intended they need the key.

    It's the sort of thing that may or may not make a difference to the quote cost, but if it's entered as being there on the quote they expect it to be correct as it forms one of the conditions of that particular quote/contract.

    From memory our insurance mentions that when the house is unoccupied they expect windows and doors to be secured (and locked if locks are fitted).

    You can usually pick up spare/replacement keys for window locks fairly cheaply, I think I picked up about a dozen for something like £20 a couple of years back as I was fed up of not having a key in every room/lock (somehow half the keys got lost), so I bought the spares and put tags on them so when someone takes them out and puts them on the side I can find them again.

    Same as deadlocking a door - if someone breaks into my property via a window they cannot simply unlock the door from the inside and load the contents into a van.

    Lots if windows don't have handles that are effectively locked when turned, our windows are wooden and the handles are a bit like internal doors when shut, so a good shake and you can get them open.

    When we has UPVC and these our insurance has always required windows to be locked when we are out.

    My new build is fitted with handles that don't have keys. Someone forced the smaller window open, reached in and opened the big window to come through.

    If we'd had key-locking windows, that wouldn't have happened.

    A determined burglar could (using a ladder) break a window enter the property and could easily escape via the front door. It's a busy road it's unlikely neighbours would hear the noise of the window breaking.

    Be careful relying on handle locks they are very easily broken by an intruder. It still would have happened it just would have taken the intruder 2 seconds to break the lock.

    If you can get your arm inside a fanlight (which many people leave open) and the windows aren't locked then you can use something like a coat hanger to open the window and get into the property. It's something we've done a couple of times with the help of a neighbours ladder when we locked ourselves out years ago!

    So, if the windows were locked and the key wasn't in the lock then this would make it more secure I assume.

    IIRC when we built our house all the windows came with locking windows and building control was not happy with them (on first floor). You can not lock them with the push of a button so the compromise was that at his next visit all the keys had to be removed otherwise all the mechanisms would have to be replaced.

    None of the windows have ever been locked.

    Elf'n'safety advise that you leave the keys somewhere near the window & obvious incase you need to leap out the window quickly at any time. Of course that makes them handier for Mr Housebreaker to use them too.

    When I organised a community safety event, we had a discussion with police & fire representatives about keys / locks on windows etc.
    We all agreed that in the end it comes down to what you are most scared about and/or what your insurance company is most bothered about!

    As for child safety, you can get windows that "lock" in the slightly open position to allow ventilation.

    From an Insurance point of view, key operated window locks (Assuming the key is not left in them) make it more difficult for a thief to gain entry through the window.

    The other advantage they have (Especially if you have dead locks on the exit doors eg door locks that can only be opened from the inside or out by the key) is that the thief cannot exit through the door and cannot open windows so would need to enter and leave through a broken window. They cannot take large items through a broken window so it reduces the amount they can steal

    We use them for our little one.

    She knows not to open the windows, but it is extra peace of mind knowing that she cannot.
