To install this lock you’ll need an electric drill for drilling pilot holes and drilling in the screws.

  1. Remove the old lock and place the new lock into the same position.
  2. If the holes line up, screw the screws in and check if everything fits into place.
  3. If the holes don’t match up, drill new pilot holes through the lock into the frame.

NB: Be careful not to drill through the frame and into any glass.

These are one of the more secure locks in this article mainly because it has the key lock and because it’s screwed deeply into the frame for stability.

Burglabar by Rishon Enterprises Inc.

Burglabar by Rishon Enterprises Inc.

This is a type of self-locking hinge that offers safety by keeping children in and burglars out. This product is made in Canada, easy to install without tools, and it’s transparent so that it’s almost invisible.

These locks can withstand 300 to 400 pounds of dynamic shear. It’s extremely strong as it was designed for sliding doors but using these on vinyl windows will work extremely well.

The only thing we don’t like about this locking mechanism is that once you stick it into place on your window, you can’t remove it and put it back as you please. You can only stick it one time and replacement adhesives aren’t available.

This Lock is highly recommended by existing customers and has a good track record. It’s very easy to install with four screws. Simply unscrew the old lock and replace it with the new one using the hardware included with the lock.

If you’re installing it in a brand new, fresh frame, remember to place the lock where you want to install it, holding it in place, and marking where you need to drill pilot holes for the screws. So the two pieces of the lock line up perfectly the first time.

This lock is known to be a very sturdy lock as the steel is of very high quality and does not easily bend under pressure.

Amazon offers these locks in packs of ten, here is an example for you to have a look.

 

Prime-Line F 2763 Window Sash Lock

Prime-Line F 2763 Window Sash Lock

This cam action lock is very easy to install and can be used on both aluminum and vinyl windows.

It is made of a heavy-duty diecast material which is very strong and will give you that sense of security that the window is securely in place and will not move when it is locked.

I’d install two locks for the bigger windows for a tighter seal and extra security just to make sure that anyone outside would have a difficult time trying to pry them open.

On smaller windows, one is usually sufficient. It often just comes down to personal preference.

It also comes in a variety of colors like bronze, silver, and white to easily match up with the color scheme you already have and blend the lock with the window.

Here is an example of the bronze-colored lock on Amazon and you can click through to see the other colors offered as well.

 

Conclusion: Window Locks for Vinyl Windows

Depending on whether you want to keep people out or keep children in will determine which lock will be best for you. Of course, if you want to cover both bases you could just go straight for the keyed locks as they’ll serve both purposes.

If you don’t have children or pets to keep in, I’d opt for the lever-action locks as they’re easy to operate and you don’t have to worry about looking for a key whenever you want to open the window. These will offer the same amount of protection from intruders on the outside with more convenience for you on the inside.

If you have really big double hung vinyl windows, using two locks can give the big window a nice, tight seal to keep you warm in those winter months. It will also give a little added strength to the window as a whole.
