Best Laptop Locks: What Kind of Lock Does My Computer Need?

Worried about leaving your laptop unattended? Now you don’t have to be. With the best laptop locks, you can lock your device while you’re away from the computer. Whether you’re leaving work for the day or are taking your work home with you, the best computer locks are designed to give you a little more peace of mind by securing your laptop, tablet, PC or smartphone.

Using your device’s docking station, you simply plug these locks into your device for a little extra security. They never interfere with your device’s functionality, and much like a bike lock, they’re designed to essentially freeze your device from opening. Unless you have the right combination or key, there’s no way you’re getting inside.

However, not all computers have lock slots, and there are many different types of laptop locks to consider. In this post, we’ll break down:

  • The three different types of laptop locks
  • What kind of lock your computer needs
  • The best laptop locks for every device.

There Are 3 Types of Laptop Locks

If you’ve ever used a sample laptop at an Apple store or Best Buy, then you’re already familiar with these security devices. With the best laptop locks, you can leave your MacBook unattended at the coffee shop without worrying about thieves. However, different devices require different types of computer locks.

There are three types of laptop locks:

  • Key or combination locks that attach to a lock slot on the side of your device
  • Locks that attach to a lock plate attached to the device’s surface
  • Locking stations that wrap around the entire laptop

The “lock slot” mentioned above is otherwise known as a Kensington Security Slot, which is used by most PC computers. Almost all laptops have this locking mechanism, which has been the industry standard since 1992. For reference, it usually looks something like this:

Newer lock slots may be longer and slimmer than the picture above, but if you’ve ever wondered what this mysterious rectangular dock was for, this is why your device has it. So if your computer has a slot that looks like this, you should be able to use most PC locks and all locks made by Kensington.

The Best Laptop Locks for Apple Devices

The second type of laptop lock is for Apple computers that don’t contain a Kensington slot. With these, you need to attach an anchor plate to the outside of the computer and then put the lock on that. This is the kind you’ve experienced fiddling around with Apple computers at the store.

Because most Mac devices don’t feature a Kensington lock slot, most Apple computer locks are in their own category. However, because of their design, they can be used with any device that has an open flat surface.

Finally, there’s the kind of lock that wraps all the way around your laptop. This type of laptop lock doesn’t require an anchor pad or a lock slot. Kensington is the standard for these locks; however, there are other types that will keep your laptop protected just as well.

When you want to add another security step before you even start to think about two-factor authorization, check out the best computer locks. We’ve rounded up some of the best options for hardware security.
