What to Look for When Buying Sliding Glass Door Locks

If you want the best door lock for sliding glass door, there are some necessary factors to consider. This section will discuss them at length to ensure your search goes smoothly.

Intended Usage

In most cases, homeowners want a sliding glass door lock for two reasons. The first one is for keeping their children from getting into off-limit areas. The second reason is providing security and stopping would-be burglars.

A 100% child proof door lock will get the job done to keep children at bay. It’ll make sure your kid doesn’t find their way into an off-limit area with ease. Many people find them endlessly helpful in closets to keep harmful objects out of reach.

But homeowners looking more toward the second reason would need a burglar-proof door lock. Please choose one that can stop burglars from lifting the door off its original track. Otherwise, it’ll end up being easy pickings for a thief.

They’re also sliding glass door locks that fit into both roles. These options will have no problem offering additional security and keeping kids out. In the end, you’ll need to choose an option that meshes with what you’re looking for in a sliding glass door lock.

Easy Installation

You don’t want to purchase an option that requires a professional install. It’s just a massive waste of your hard-earned money. There are plenty of high-quality options available that are effortless to install.

In fact, you can set up most child proof sliding glass door locks in under a minute. It consists of opening the adhesive surface’s seal and placing it in your desired location. What’s the point of spending extra cash on a profession when top-tier options are installed so easily?

Durable Design

The biggest issue for locks is corrosion and rust. If left unchecked, these issues can affect the lock’s appearance and effectiveness significantly. You’d be wise to consider only getting all-metal door locks when they’ve proven to be corrosion-resistant.

Customer reviews can be incredibly helpful in determining a lock’s durability. These resources will make it clear whether the sliding glass door lock held up well.

Your Type of Sliding Glass Door

Sliding glass doors often consist of vinyl, wooden, or aluminum material. As a result, you’ll need to find the types of sliding glass door locks that work with yours. It might seem obvious, but it’s alarming how many homeowners fail to consider this aspect.

Most options will work with all three materials, but some don’t. It’s also worth noting that many of these locks won’t work with screen doors.

Easy to Use

Sliding glass door locks are a little bit different than most products when it comes to usability. You want an option that’s easy to use but difficult for children and burgers to bypass. It’s a difficult balance to find within this marketplace.

I’d also suggest thinking about the needs of everyone in your home. It shouldn’t only be easy to operate only for you; your family members will also need to use it without any issue.

Are There Smart Locks for Sliding Glass Doors

There isn’t any commercial smart lock solution for sliding glass doors. This issue arises because of a large number of sliding door designs. As a result, each option ends up locking and unlocking differently.

How Can I Make my Sliding Glass Door More Secure

There are several methods of making your sliding glass door more secure. But here’s a quick list of my favorite choices to provide your home with a bit more security:

1. Installing a security system
2. Upgrading the locking system
3. Slip in a sliding glass door lock bar
4. Close your curtains
5. Install a sliding glass door deadbolt lock

If you stick with these methods, your sliding glass door should become a lot more secure in no time. You’ll soon feel a lot safer inside your home.

How Do You Lock the Sliding Glass Door from Outside

If you want to lock your door from outside, an installation of a lock and key will be necessary. It might seem a little inconvenient at first. But these additions will provide better security and help prevent intruders.

How to Fix the Sliding Glass Door Lock

The process of sliding glass door lock repair isn’t overly complicated. The following five steps will make sure the job becomes straightforward.

1. Remove the screws attaching your broken door lock to the door. Take the old door lock down to a local hardware store and use it as a reference point for your sliding glass door lock replacement. It’ll save you a ton of time and prevent multiple trips to the hardware store.
2. Please take out the new sliding glass door lock of its packaging and look over all the parts. It’s an essential step because these products tend to vary significantly from one another.
3. Install its locking cylinder into the door’s lock frame. Proceed to place the key into this cylinder and see if the lock turns correctly.
4. Place the locking (exterior) side of your lock’s frame into the door. You then set the interior side into the door. Place the door’s handle over the screw holes on the door frame’s interior side. Next, install the screws into the holes and hand tighten them. I’d recommend using a Phillips head screwdriver.
5. Slide your glass door closed and use the lock. Test and make sure it works properly.

Conclusion

The best sliding glass door lock should now be well within your reach. It’s a simple matter of using what you’ve learned and applying it to your search. From there, the entire process will become a straightforward and easy task.
