Different Types of Sliding Door Locks, Explained
Now that you know what types of sliding door locks are out there, let’s delve into them in more detail to determine which type of lock is best for you.
1. Mortise Locks
Mortise locks are the most common type of sliding door lock and come preinstalled on most sliding doors. They are installed on the inside door panel and can only lock from the inside.
Mortise door locks are an inexpensive option for those who aren’t concerned with locking and unlocking their doors from the outside of the home.
They can be less durable than some of the other options discussed here but are an excellent choice for those looking to lock their doors without spending a small fortune on a fancy lock.
2. Keyed Locks
As you might guess from their name, keyed locks provide a lock for your sliding door that you can lock and unlock by a key from outside the home.
These are a promising option for anyone who wants a guaranteed way to open the door from outside, such as parents of children old enough to lock them out accidentally or people who are prone to locking themselves out of the house.
These locks aren’t specific to sliding glass doors, so you’ll want to double-check that whichever one you decide to purchase is compatible with your specific door. These locks can also pose a slight security risk because keyed locks are easier for criminals to pick and open using an alternative tool.
3. Loop Locks
Loop locks are among the easiest to install and most durable options on our list. They consist of a mounting plate for you to install on the inside door jamb and a keeper to mount on the sliding door itself.
The concept is simple: the locking bar connects the mounting plate to the keeper, ensuring that you can’t open the door from outside.
Loop locks aren’t as secure as some harder options, such as a double bolt lock, but it provides an affordable way to secure your door against most minor threats. You can only unlock this one from the inside, so you might want to skip it if you need to be able to open your locked door from outside your home.
4. Double Bolt/Deadbolt Locks
Double bolt locks provide an extra layer of security and are easy to install on most sliding doors. They work by preventing the door from lifting or removing it from the track on which it slides. Because you’ll install this lock about the handle, it can work with any other locks on your door.
To install a double-bolt lock, you mount the bolt part of the lock on the door above the handle and the fixed part of the lock on the door jamb. You secure the door by sliding the bolt closed. You can only open this lock from the inside.
5. Toledo Locks
Toledo locks are an affordable and very secure option if you are looking for additional security on your door. You can easily install these in multiple places on your sliding doors and nearly any other type of door and window in your home. They come with a key to open and secure the lock.
Toledo locks are among the most secure locks on our list of options. They are hefty and resistant to bolt cutters and hacksaws because the bolt will spin under pressure. The hidden nature of the mounting hardware makes them even more secure.
6. Security Bars
If you are no stranger to sliding doors, you’ve probably seen the age-old trick of sticking a piece of wood or other material behind the door, stopping it from sliding.
This foolproof trick has been around for generations because it works – Shy of pushing the door open with enough force to break the wood (unlikely), it’ll stop people from entering your home.
Security bars take inspiration from the old wood-in-the-door trick and provide an affordable option to secure your sliding door from the inside. Most security bars are adjustable, so you can size them to fit your doorframe perfectly.
You can also purchase temporary or fixed options, depending on what you prefer. If you have young children in the house, this is a good option for you. A toddler’s little hands will have difficulty prying a wedged security bar out of the door frame.
7. Guardian Locks
Guardian locks are another excellent option for child-proofing your sliding doors. There are a variety of child locks that can stop children from opening the sliding door, and some will even prevent unwanted guests from entering from the outside.
A benefit to child locks is that many options can secure the door in a partially open position instead of simply keeping it closed or open.
On the other hand, most child-locking options mean to stop children from getting through your door and might not be much help against an adult entering your home with malicious intent.
8. Barricade Locks
Once you secure the mounting plate to your floor, a barricade lock prevents the door from opening. These locks are easy to install but require more equipment than some other options, namely a power drill. You’ll want to ensure that you have one available before purchasing this type of lock.
These locks are very effective and durable but will only work on doors that slide on an inside track, so check your door track before choosing this type of lock. You’ll only be able to open this lock from the inside of your home.
9. Sliding Track Locks
Sliding track locks attach to the inside track of your sliding door to prevent the door from opening. Like barricade locks, you’ll need to ensure that this is appropriate for your specific type of sliding door.
These locks are easy to install by simply attaching them to the track of your door.
However, they can be less secure because they are more flexible and easier to push off the track than other options. Some individuals will install multiple sliding track locks on one door to improve the likelihood of resisting pressure or break-in attempts.
10. Smart Locks
It should come as little surprise that there are smart options for your sliding door lock in this day and age. Although once a more difficult-to-find item, more companies are releasing smart locks for sliding doors.
Most of these will integrate with other smart home products, and you can control them from your phone or other personal devices.
Although a more expensive option, smart locks are a great option if you need to open your door from a distance, such as for your pet when you are away from home. These are the only locks on the list that usually require an expert to install.
After all, they are a little more complicated than your basic sliding door locks. You’ll also want to consider that they are subject to misbehaving if your Wi-Fi or electricity is spotty, which can hinder your ability to control them from a distance.
