Best Sliding Glass Door Lock - Buyers’ Guide
Do I really need a Sliding Glass Door Lock?
A lot of people think that it’s pointless to have a sliding glass door lock. They think that no matter how strong the lock is, the burglar can just break the glass of the door with anything heavy and get inside regardless. While this may be true, having a lock on your sliding glass door can still act as a strong visual deterrent for a majority of burglars.
Most burglars don’t want to create a commotion when breaking in. If you have a lock on your sliding glass door, they have no choice but to create a lot of noise in order to get in. As a result of this, many burglars will decide against breaking into your house.
What are some things to consider before buying a Sliding Glass Door Lock?
Before you go out and buy a sliding glass door lock, it’s important to know what factors you should look into. These will help you determine whether that lock is appropriate for you or not. Some of these factors are:
Mounting Mechanism
Different sliding glass door locks have different ways in which they mount onto your door so you have to keep this in mind before buying a certain lock. For some locks, you may have to drill holes into your sliding glass door while for others, you may not need any tools at all.
Who Lives in Your Home
You have to consider who lives in your home when you’re going out to buy a sliding glass door lock. Some locks are exclusively designed to keep burglars out. While other locks are designed to keep people inside your house such as children or family members with special needs safe.
If you have someone like that inside your home, you may want to consider a lock that also has child-proofing capabilities.
Visibility and Aesthetic
It’s important to consider just how visible the lock is going to be when you mount it onto your sliding glass door. You should also consider whether or not it blends in with the interior decor of your home or not.
Another decision that you have to make is whether you want the lock to stand out or blend in. Both of these scenarios can have different effects on a potential burglar’s mindset.
How do I put a lock on my Sliding Glass Door?
Start by cleaning your glass door with warm soapy water and let it dry completely. Identify the part of your door frame behind which there is no glass. You can identify this by tapping on the door frame with a screwdriver until the sound changes.
Once you’ve identified this section, hold the lock up to it and mark the screw holes with a marker or Sharpie. Drill out the holes in the sections that you have marked and screw in your lock into these holes.
How can I lock my Sliding Glass Door from the outside?
It’s generally a good idea to only have a sliding glass door lock on the inside. If you really want to have one on the outside then we suggest that you get a lock that only opens with a key.
How do I maintain my Sliding Glass Door Lock?
Locks are generally very durable and do not require a lot of maintenance. It’s a good idea to keep an eye on your lock and check it from time to time though. Spraying your lock with a lock lubricant such as WD-40 every few months will keep it working smoothly for a very long time.
Best Sliding Glass Door Lock - FAQs
My Sliding Glass Door Lock isn’t working. What could be wrong?
If your sliding glass door lock was working before but has now stopped working then this may be because it’s gotten too rigid. This can cause the sliding glass door lock to jam. This can easily be fixed through the use of a lock lubricant. Just spray it inside your lock and try it out. Your lock should start working.
If you’ve just installed your lock and it’s refusing to work then this may be because you haven’t installed it properly. We suggest consulting the sliding glass door lock’s manual if this is the case.
How can I be sure that my Sliding Glass Door is properly secured?
You can ensure this simply by testing it yourself. Just lock your door and try to get in without unlocking it. This will give you a good idea of how secure your sliding glass door lock really is. If you're still not satisfied with the security of your sliding glass door then you can look towards other places. You can make it more secure by installing shatter-proof glass, etc.
How does a Sliding Glass Door Lock work?
Different locks work in different ways. The most common sliding glass door locks are mortise locks. These work by having a bolt that fits into a mortise or pocket next to your door frame.
Other locks that work on sliding glass doors work by lifting it off the track, thus, making the sliding glass door unusable.
Are there smart locks available for Sliding Glass Doors?
Yes, you can buy smart locks for sliding glass doors which can then be operated through different access mechanisms. These can be an electric keypad or even technologies such as Bluetooth. They can be quite expensive with prices going up to $200.
Is there a way to make my Sliding Glass Door even more secure?
You can only make the lock so secure. If you’re worried about the security of your sliding glass door then we suggest making the door itself more secure. This can be done by adding glass window film, installing shatter-proof glass. You can even install a glass-break sensor or alarm.
Would putting a deadbolt on my Sliding Glass Door be a good idea?
Yes. Although, it will require a lot more time and effort than other kinds of locks. Putting a deadbolt on your sliding glass door will definitely make it very secure.
Is it easy to break through a Sliding Glass Door?
It definitely is relatively easy to break into a sliding glass door. All a burglar really needs is a brick or something similar that’s heavy to break the glass and get inside your home.
Is there any way to secure my Sliding Glass Door without a lock?
As we mentioned earlier, there are other ways of securing your sliding glass doors. These can be through installing shatter-proof glass, glass-break sensors or alarms. However, if you don’t have a lock installed then the burglar won’t have to break the glass at all. They can just simply open your sliding glass door and walk in. This is why we suggest that you install a lock first before you start securing your sliding glass door further.
