Locks are perhaps the most essential element of robust home security. Whether buying outdoor locks, gym locks, or window locks, one always tries to have the best ones to prevent theft. When my cousin moved to a new house, I helped him with most of his home security purchases as a home security expert. However, I had difficulty convincing him to invest in good vinyl window locks.

Most of the time, we overlook the need for a window lock. We often look for the best locks for doors but spend little time thinking about windows, especially if one has to buy locks for vinyl windows. However, most of the time, thieves are craftier than us and break into the house through weaker points like windows, shafts, and backdoors. Here is one study that just confirms that. Also, window locks are an added security feature for your children and pets and help keep them inside when they shouldn’t be outside. So, investing in a lock for your vinyl window is a wise decision.

While looking for a vinyl window lock for my cousin’s house, I realized there are not many articles written to help people find good vinyl window security locks. This acted as a prompt for me to write this article.

  • You are concerned about the security of your house while you are away from home.
  • The pre-installed locks of your windows are not that strong. Hence, you need another layer of security.
  • You have children at home, and hence, you need to childproof your house for their security.

  • You are looking for a vinyl window lock replacement as your existing locks are worn out.

What Should You Look For While Buying Vinyl Window Locks?

Whether you are purchasing the best gym lock or the best window lock, it is essential to understand what you should look at. You should keep in mind some important aspects while buying a lock for your vinyl window.

What Should You Look For While Buying Vinyl Window Locks?
  • Size Of The Window: The lock that you will buy for your window depends largely upon the size of the window. Majority of the people want their window locks to blend with the surroundings. A standard window is sized somewhere around 48 inch X 60 inch. However, AC windows are smaller. Hence, knowing the size of your window will affect your decision of which lock to buy. Also, the track height and track thickness of the window is also a point to be considered. Most tracks are about 1.5-2 cm high and 1.5-1.8 cm thick. So, looking for a lock that fits is crucial.
  • Budget: Window locks are available in varied budget options based upon their brand, material, level of security, etc. A good vinyl window lock will cost you somewhere between $8-20 depending upon its type and the features it comes with.
  • The Level Of Security: Whether you need a lock for childproofing, or to keep the burglars at bay. Whether you need a lock for ventilation purposes, or as an added layer of security when you are away. The lock that you will buy for your vinyl windows, depends upon the level of security that you need. Understanding the reason why you are buying a window lock will help you identify the level of security that you need.
  • Material Of The Lock: Locks are available in a variety of materials like plastic, steel, aluminum, etc. If you are looking for a more secure lock then you should look at a lock that is made of a sturdy metal or alloy. If you are pet proofing or childproofing your home, plastic locks work fine and are affordable. Also, if you live in a moist place, buying an anti-rust lock is a requisite.
  • Ease of Installation: The installation process of locks varies to a great extent. Some locks can be easily installed while some need professional help to install. The ease of installation that you are looking at will help you select the lock for you. There are locks available that do not require any drill or screw to install. So, if you avoid making any structural changes to your window, these locks may suit you the best.
  • Suitability: Not all locks can be installed on a vinyl window. Keeping the filter on while choosing the one for you is important. There are many users who end up buying a lock that is not compatible with their windows. However, most locks are returnable if bought through amazon.com, still why mess up?

If you answer the above question yourself, it will help you choose an appropriate lock as per your needs. For example, if you need a window lock while traveling to stay safe, you should consider buying a smaller lock. If childproofing is the only reason you need a lock, a plastics lock will work well. If security is your concern, plastic is not a great option as it is easier to break in. It is also crucial to look for the lock that fits well on your window.
