    The vendorRefunded and took the item back, but I recommend them if you need to keep windows locked for little ones.


    It is easy to install and the toddler won't get out of the window.


    It's a good value and easy to install.


    The Anderson windows do not work with this type of lock and it's great, but I didn't buy 2 because they don't work with our windows.

    FAQ

    Q:

    Is it possible to use the same key for 3 windows?

    A:

    If one wants to get a set of the locks with the same key number, they have to get a numbered set of keys.

    Q:

    I need a different number than the ones I got, can I order a specific number?

    A:

    A lock smith can change them at a cost of 3 to 4 dollars a lock.

    Q:

    I'm wondering if I will be able to open the window when it's installed, because my windows are shallow.

    A:

    It took me so long to answer that I don't check it often.

    Q:

    Does the product come with a special tool for the security screws?

    A:

    The item comes with a standard flat head screwdriver that can only be removed with specialty bits or grinding.

    Q:

    The locking mechanism fell out, how do you get rid of the security screws?

    A:

    If you don't want to use a pair of pliers, you can drill out the heads of the screws.
