You can have this door lock installed on aluminum, vinyl, and wooden materials. It fits well on sliding doors, but you can only install inside the track.

I will say a big yes to this. There are top-of-the-line door locks for sliding glass doors on the market. Plus, you also don’t have to break the bank to get one. All you need is the right information to help you make an educated decision. That’s it.

So, I am going to walk you through an unbiased review of some top sliding glass door locks that will make an excellent choice for you. Let’s go over them quickly.

Things To Consider Before Choosing A Sliding Glass Door Lock

A door lock is an essential piece in any building. This item provides numerous benefits, such as preventing illegal entry into your home and ensuring the safety of your kids.

As a parent, you should know how difficult it can be to keep an eye on the kids all the time. It is more complicated, even in today’s connected world. But you must ensure your children don’t get into off-limit areas in your home without your supervision. One such danger zone is a swimming pool.

So, if you are eager to splash the cash on the right sliding door lock for your property, here are factors you need to consider.

Price of the door lock

How much does the sliding door lock you are eyeing cost? If you haven’t figured out by now, it’s high time you did so. Knowing the actual price will enable you to plan your budget.

You also don’t need to break the bank to get a good quality door lock. That’s why reviews like these and conducting market surveys are equally important. Through these means, you will be able to figure out the price tags of several locks and make an informed decision regarding the door lock to get.

Most packages also come with as many as two locks, which could help reduce your spending. You can use the extra lock on another door, instead of splashing the cash on a new one for each entry point you want to keep secure.

So, check the price tag and find out if the pack contains an extra lock you can use on another sliding glass door on your property. But above all, ensure you don’t compromise on quality.

The intended use

I presume you already know the most crucial reason you are getting a door lock. If you don’t, just take out time to have a rethink.

There are perhaps, two main reasons for using a door lock for sliding glass doors. One is for child safety, which involves keeping your kids away from off-limit areas. The second option is to prevent burglars or illegal entry.

The two options mentioned are equally important. However, most people might have a specific interest. So, if your reason for getting a lock is to ensure the safety of your kids, a 100% childproof lock will do the job.

In short, you will need a childproof sliding glass door lock for doors guiding an indoor swimming pool in your property. Most of these door locks can also be used in a closet to prevent kids from getting their hands on harmful objects.

On the other hand, your utmost priority might be to safeguard your belongings or family. In this case, you are going to need a burglarproof door lock.

When buying a burglarproof door lock, ensure you get a product that would prevent burglars from lifting the sliding glass door off its original track. It happens to be one of the ways by which burglars get into homes illegally.

However, there are sliding glass door locks that can serve both purposes. In other words, such locks can provide extra security (prevent illegal entry) and childproof. So, if your intended use of the door lock is to prevent unlawful entry into your property and keep children away from off-limit areas, then consider door locks that can serve both purposes.


The last thing anyone would be hoping for is to spend extra bucks to install a newly acquired sliding door lock. That will hike up your budget. And if you plan to install the locks on more doors, you will end up spending more money.

The question is, do you have to hire an expert to install a lock for your sliding glass door? Well, not really. Although there are highly mechanical door locks that would require hiring an expert, when you are only going for a replacement, you don’t need one.

There is a myriad of sliding glass door locks that are a breeze to install. You will find many of them listed here. Therefore, you shouldn’t be spending any extra money to hire an expert to have your door lock installed.

Most childproof door locks for sliding glass doors could take less than a minute to install. All you are required to do is open the seal on the adhesive surface and place it wherever you desire. A good quality door lock should have a strong adhesive that will resist forced entry to some degree too.


If you don’t see this as a big deal, you better have a change of heart. Corrosion can reduce the appearance of your door lock. And you know, the door of your home, which contains the lock, is the first point of contact with your visitors.

So, if you are getting an all-metal door lock, ensure it is corrosion-resistant. Such doors tend to retain their appearance, irrespective of the weather condition.

Type of sliding glass door

You will find different sliding glass doors on the market, not just concerning their design but the materials used.

Most sliding glass doors come made of aluminum, vinyl, or wooden material. Therefore, before you splash the cash on a door lock, find out if it works for the type of sliding door you have. Most locks would work for all three materials; vinyl, wood, and aluminum. You should also have in mind that most locks won’t work on screen doors.

Ease of use

If your motive is to keep your children away from a balcony, swimming pool, or dangerous area, the focus should be to use a lock that will be difficult for them. The same thing applies to burglars. Your goal would be to get a lock that would make it impossible for them to burgle your house.

You shouldn’t forget to consider your needs, and perhaps, the elderly ones, or relatives in your home when choosing a door lock. So, whatever lock you are getting, ensure it is easy for you to use.


Another critical factor to consider is the finish. The finish of the lock you are settling for should match with the entire sliding glass door. Otherwise, the door would look a bit weird and unattractive.

If you are choosing a door lock, particularly one that would serve as a replacement, choose one with the finish that matches the original but already damaged lock. The good thing is most locks have multiple finishes. So, you should find your preferred choice of lock without stress.

Wrapping It Up

Door locks can help to prevent the unexpected from happening. They can keep your kids away from balconies, swimming pools, or other off-limit areas in your home. You also need one to prevent burglars from ransacking your home and carting away properties you acquired with your hard-earned money.

However, there are myriads of door locks available, making it difficult for buyers to make a choice. Notwithstanding, the details provided in this post and the features of the products discussed will help you to make the right choice. You will find products that will meet your needs on this list of the best sliding glass door lock.
