Another excellent option is a keyed door lock. These things prevent intruders from jiggling a lock loose. The way it works is that you bolt it onto on your door, and the movable pin locks it into the frame. Most people can install this lock system in just a few minutes.
The key adds an extra element of security to it because there’s really not way to get it open without it. However, in case of fire or something similar, be sure to have the key handy and in a location that every household member knows. For that reason, we generally only recommend a keyed lock if you want to be able to unlock it from the outside.
- Surface mounted
- Comes with a key included
- For doors, sheds, a barn, etc.
- Easy installation with a few simple tools
- Requires a half turn to lock and unlock
“It’s very durable and easy to put in. And it’s easy enough to remove if you’re only using it temporarily. Great value for something that actually works. I’ve tried some of those quick release ones but never had much luck with them.”

The benefits of installing the proper sliding glass door lock in your home or office is that they are safer, easier to use, and more secure.
Today’s technology offers a variety of products for sliding glass door locks that will help keep criminals away while allowing your family and employees to exit rapidly in the event of an emergency.
How To Install Locks For Sliding Glass Doors
Capitalize On Technology With Your Sliding Glass Door Safety Latch
So many clients invest in surveillance cameras and alarm systems and neglect one of the most basic entrances to their home or office. Their patio door lock is antiquated and is inviting disaster.
Cutting edge technology for a home alarm system won’t help if your ancient method of using old locks and makeshift barriers can’t keep your home as safe as possible. Often the sliding glass door is the favorite entrance and exit of employees and family members.
Piece Of Wood: Not Ideal
We’ve all seen this. Enter a home or office with cutting edge camera systems and the sliding glass door is held secure with a piece of scrap wood. This can be effective in preventing unwanted entry (to a point), but it can also make it difficult for people to exit efficiently.
This is especially problematic in an emergency.
Luckily, advances in technology have made the locks inexpensive, easy to use and secure. They are made from steel, aluminum or other similar strong materials. They can handle some force being put upon them and have a much higher breaking point than a piece of wood.
Most locks are keyless. This means you don’t have to worry about misplacing your keys and taking forever to open that door when you want to get out.
Of course, there are also some available with keys, but we generally only recommend those if you want to place the lock on the outside, in order to make the sliding door a primary entry point to your home or office.
Stronger Than Ever
Stronger than typical locks, these locks offer a more secure solution for your home or office. And if you still have the difficult to use and unsecure traditional locks, the new technology will astound you.
Understand The Dangers Of A Sliding Patio Door
Unfortunately one of the nicest enhancements to your home or office comes with a degree of danger. Sliding glass doors can welcome criminals and be dangerous in the event of an emergency.
Open the police department’s crime summary or crime log in your local newspaper and you’re bound to find warnings about these doors. With violent crime rates escalating in the United States there is no better time to take every precaution in securing your assets, your home, your employees, and most importantly, your family.
Sliding doors can also be a hindrance to exiting your home of office in the event of an emergency. Traditional locks and security methods create unnecessary barriers to exiting in a safe and efficient manner.
Sliding Glass Door Weaknesses
Here are the main patio door weaknesses and thus, the main reasons you need a good lock on those doors.
Simple Latches On The Door Handle
Think you’re good about always locking your patio door? It may not be enough. If the latch is too simple, a burglar can unlatch it by just jiggling your door. It may not even take that much force to do this and it can also be broken quite easily even without a lot of force being applied.
This problem is easily prevented with a more secure locking system. You don’t necessarily need keys, but you do need something that can withstand a bit more force than the average patio door.
They’re Hidden Away From View
Most people have patio doors for a basement suite, or in their backyard. This means that they’re hidden from view and they can make an easy target for criminals. This makes it all the more important to secure them properly.
You Can See Through Them
Criminals love to see what they’re getting. A wallet sitting on the counter? A brand new laptop that they can easily grab and run with? A cabinet full of liquor.
Keep your blinds closed when not at home please!
They’re Easy to Break
A small hammer is usually all it takes to break a patio door. This is why an alarm, or security system is all the more important to keep your home or business safe.
Enjoy Your Patio Door Lock
Luckily advances in technology have made the newest sliding door lock choices easy to use and secure. Rather than stuck behind unwieldy barriers, your family and employees will use your sliding glass doors frequently and safely.
Isn’t that what doors are for? To be used?
As long as they aren’t used by criminals!
