How Do Laptop Locks Work? (Important Safety Measures)

| Updated:

Are you concerned about leaving your laptop unattended? You no longer have to be. You can use laptop locks to secure your device while you are away. Laptop locks make you feel more confident and protect your laptop and all the valuable data within from theft.

Furthermore, laptops are more susceptible to theft than standard desktops due to their portability. This makes using a laptop lock necessary, especially if you work in public areas with many people around.  

Fortunately, laptop locks are affordable, so you don’t have to spend a lot to secure your laptop. So, are you wondering how laptop locks work? We’ll discuss how in this article. Also, we will highlight why you need a laptop lock and things to consider when using a laptop lock. 

Why You Need a Laptop Lock

Laptop theft is a serious threat to laptop owners. Did you know that a laptop has a 1 in 10 chance of getting stolen? That’s quite a concerning figure.  

Losing your laptop can be a gut-wrenching experience. Laptops contain all our valuable data, such as photos, files, passwords, etc., and if stolen can jeopardize our security and safety of your sensitive information. As a result, it’s crucial to identify how to safeguard your laptop and data from theft.

Moreover, you can protect your laptop in different ways, including following security tips and using various software and hardware tools. You can find a wide selection of tools on the market that will assist you in securing your laptop; one of these tools is a Laptop Lock. Here’s an example of how laptop lock looks like:

How to Use Laptop Locks

Check the back or sides of your laptop to see if it has a Universal Security Slot (USS) compatible with a laptop lock. The USS is a round hole on the back/side of a laptop.

Many laptop models have an image of a lock next to the USS, about a third of an inch in size. Most PCs on the market today have a Universal Security Slot. If you’re unsure whether your laptop has a USS, check the internet or contact the laptop manufacturer.

If your laptop has a USS, purchase a laptop lock and unpack, then remove the twist tie around the cord. Wrap the security cord around a stationary object — like a heavy table — and insert the lock through the cables’ loop to secure it. Ensure the stationary object you use is heavy enough to make theft difficult. So, choose an object that’s difficult to dislodge.

After that, firmly insert the head of the laptop lock into the USS until you hear a click. Once you’ve inserted the lock into the USS, you won’t be able to remove it unless you enter the lock combination or use the key that came with the laptop lock.

Furthermore, to unlock a laptop lock with a key, insert the key into the laptop lock and twist the key. Moreover, if you have a lock that unlocks through a combination, input your combination by adjusting each wheel until you set the correct code. Note that most laptop locks that use a combination require a four-number code.

Things to Consider when Using a Laptop Lock

Here are two factors to consider when using a laptop lock.

Anchor Point

The anchor point you use for your laptop is very important. Even the best laptop locks are useless if you don’t connect them to a solid anchor point like a cubicle wall or heavy desk. It would be best to secure the lock to something stable and heavy. Even though a burglar could snip the cable with a wire cutter, doing so will take time and draw too much attention — something thieves don’t want.  

The Lock Slot of Your Laptop

A large percentage of laptops have a security lock slot built into their frame. Generally, there are three types of lock slots. Ensure you purchase a laptop lock that matches the slot. The Kensington Security Slot is used by the majority of laptop manufacturers. 

Furthermore, Lenovo’s new, portable laptops like the Ideapad and Flex laptops, among others, use Kensington’s new Mini Security Slot to save space. On the other hand, some Dell laptops, like the XPS models, use a different lock slot from Noble Locks. Noble Locks is a company that produces security products for computers. 

In addition, Apple does not include lock slots on its MacBooks. However, some companies have created locks that clamp tightly onto the lid or attach to the MacBook’s rubber feet. If your laptop comes with a lock slot, it’s most likely from Kensington, except you own a Dell laptop.  


Safeguarding your laptop is an important step to ensuring your investment is safe. Laptop locks effectively protect your laptop and save you from embarrassing data leaks and spending money on a new laptop. 

Now that you know how laptop locks work check if your laptop has a slot. If it does, research the maker of your laptop’s lock slot and purchase a lock for your laptop. What do you have to lose?

Frequently Asked Questions

Does Every Laptop Have a Lock Slot?

In general, most laptops have a lock slot. Moreover, most laptops manufactured after 2000 have a security lock slot. This slot accommodates a laptop lock, making it more difficult to steal the laptop.

How to Reset the Combination on a Laptop Lock

First, input “0000” on the laptop lock; this is the preset combination on most laptop locks. Then, insert the reset tool or a screwdriver into the reset screw or pin. Set the reset pin or screw to the right position. You might need to rotate the pin 60 ° to 90 ° clockwise or counterclockwise.

Furthermore, to select a new combination, scroll the combination dials and set a new code. We recommend you write down this code somewhere accessible, just in case you forget. Lastly, reset the pin or screw to its original position. Before connecting the laptop’s lock, test the new combination code.
