Smart locks are a staple in most smart homes. They are extremely convenient and add to the efficiency of our homes. Most of us have at least one in our house, usually on the front door. But what about the other doors in our house? In particular, that back patio sliding glass door.

These sliding glass doors are obviously much different than any other door in our home. They slide and have a latch locking mechanism that can be easily defeated by an experienced thief. They can also be the biggest piece of glass in our home as well, adding to the concerns around security.

Unfortunately, at the time of writing, there was not one company that offered a truly smart and secure smart lock for sliding glass doors. Well, none that we could confidently recommend. There have been some companies that have tried to break into the space but never really got of the ground like Padiolock and few others.

When I think about smart locks for our patios doors, there are a few things I think are of upmost importance when considering any device. Those are:

  • Will the lock fit into your existing smart homes ecosystem? If your home is controlled by Alexa, Google Nest or whatever, you will obviously want this lock to be able to be integrated into your home seamlessly.
  • Will the lock add an extra layer of security to my patio door? Patio doors are notorious for being the point of entry for many home burglars. The reason for that is the locks on these doors tend to be less secure and easily defeated. A smart lock should make that a non-issue.
  • Will the lock allow for keyless entry and extra automation? It is a smart lock, so there should be something smart about it, right?

Again, we have yet to find the perfect smart lock for sliding doors. No one has seemed to put much resources into developing these yet. But as they come out we will surely be writing about them.

Instead of leaving you hanging, we have gathered a few products that add some smarts, security and ‘wow’ to your sliding patio doors.

Keyless Entry

When I think of smart locks in general, one of the most important features is keyless entry. Having a lock work with geofencing or bluetooth to automatically unlock would be ideal, for sure, but this key pad lock is a decent option.

Lockey Surface Mount Hook Bolt

The Lockey 2500 is an add on to your sliding door and allows for keyless entry. It does only allow for on key pin, so you will have to share that around with your friends and family who will be using the lock. This one also comes with two keys for locking and unlocking. Yeah, I know, keys are old fashioned but having that extra accessibility is pretty nice.

These locks are designed for sliding doors or other doors where a hook bolt is required. They are weather resistant and come with a lifetime warranty. Changing the code is pretty easy as well, you can find video instructions here.

Below is a quick video of the lock in action:

Now this lock does not check all of the boxes for our ideal smart lock, but it does add a better functioning lock and a keyless entry.

Automatic Opening

Above, I mentioned smart door locks should add some automation to that door. Well, the autoslide does just that but in a way cooler way than you might be thinking.

Autoslide AS01BC Automatic Patio Door Starter Kit, Black

The Autoslide is a DIY system that completely automates your sliding doors, meaning it opens and closes the door for you, hands-free. The Autoslide has two ways of opening the door: with a remote and with infrared motion sensors.

For whatever reason, the sensors were not being offered on Amazon when this article was written. You can find the motion detection sensors here. If you want the true hands free automatic door experience, you will want the motions sensors.

Here is a video demonstrating how it works:

These will work with doors up to 200 pounds. Installation is fairly easy and it comes with a DVD that shows how it is installed. They have a 2-year warranty, that should add some peace of mind if you plan in investing in one of these as they are a bit pricey.

They even have a model for pets! The AutoSlide smart tag door system allows your pet access in and out of your sliding door without you having to open and close it for them.

This bundle comes with an RFID tag that you can attach to your pet’s collar. When they are in a preset distance from the door, it will open. That range can be 3 feet, 5 feet or 10 feet.

This will definitely add that ‘wow’ to your sliding door and make it a bit more efficient, but it still does not integrate into your smart home ecosystem. As of right now, this does not work with any of the voice assistants allow for remote controlling from your smart phone.

Nonetheless, it is still really cool!

Extra Locks

One major concern with existing sliding door locks is the lack of security they actually provide. Anyone can use a screwdriver to pry into most sliding glass doors. They really are not effective at all. If you are just looking to add some heavier reinforcements to your door, why not just add an extra lock to the door?

When I was younger, our sliding door lock was an old broom stick cut to fit in between the door and wall. Although effective, there are other options out there. Options that are just as, if not more effective and much more presentable.

CAL Lock Smart Bolt Lock Sliding Door

The Cal Lock is an easy and effective way to beef up the lock on your patio door! It is a double bolt lock that attaches easily to your existing door. It has been tested to withstand over 1000 pounds of force. These are not only for sliding doors but can be used on french doors as well.

Here is a quick video on installation. They really are easy to set up and come in white and black to better match your door color.

now, this lock is by no means smart. This is simply a way to beef up your existing door lock. If you are solely trying to add some more security to your home, this will definitely be a step in the right direction.

Motion Sensors

If added security is your main objective, you can also add a simple motion detector to your door. With motion detectors, you can be alerted of anything happens around your sliding glass door,

This Samsung SmartThings motion detector works with Google, Alexa, SmartThings, and Z-Wave and ZigBee communication protocols. Although it is not a lock, it does help with security and will add to your peace of mind.

You could also add a glass break detector, but I hear they can be overcome if the burglar knows what they are doing. There really is no easy way to get around a motion detector, especially if you don’t know its there.

Assure Lock for Andersen® Patio Doors

These are the real deal smart locks. Only problem is they are specifically for Andersen hinged doors. They will not work on your existing sliding glass doors.

If you are planning on upgrading your patio doors, you will want to consider these doors and this lock. You can find more on the lock itself here.

I do not have Andersen doors and probably won’t for a while. From what I was able to dig up on these, they can be retrofitted if you already have these doors or come with new installs. You will have to reach out to your local Andersen dealer to find out more. You can find your local dealer here.
