The Best Laptop Lock: Our Picks

Guide: Questions you should ask yourself before buying a laptop lock

What is a laptop lock?

Not only can you use a lock to connect a bicycle to a bicycle stand, but you can also secure a laptop with a laptop lock. A laptop lock is a safeguard for the laptop so that it cannot be removed without authorisation.

A laptop lock consists of a sturdy and long cable that has a lock, e.g. combination lock, at the end.

A laptop lock is a practical and inexpensive solution for securing your laptop with sensitive data.

This security lock is only an additional protection for your laptop and is mainly used to deter thieves.

How does a laptop lock work?

A laptop lock works in a similar way to locking a bicycle. The laptop usually has a small opening to which the special lock can then be attached.

The lock is encrypted with a numerical code or a key. The cable is then attached to an object, e.g. a table or a pillar. This way, no one can steal your laptop.

Who is a laptop lock suitable for?

A laptop lock is suitable for anyone who wants to protect their laptop or notebook from unauthorised access or theft. You can use a laptop lock at home, on business trips, but also everywhere on the road.

If you're in a café or on a train and need to go to the toilet, but don't feel like taking your laptop to the toilet, the laptop lock comes into play. This way you can leave your laptop unattended for a short time and don't have to worry about it.

What are the alternatives to a laptop lock?

The only alternative to a laptop lock is to take out insurance against theft and install software that protects private data.

In addition, it would certainly make sense to set up a tracking app on the laptop, as you can locate the laptop via GPS after installing this app.

Decision: What types of laptop locks are there and which one is right for you?

If you want to get a laptop lock, there are two alternatives you can choose between:

  • Laptop lock with combination lock
  • Laptop lock with key

The combination lock is very common. The combination lock usually has a code with 4 numbers to choose from.

With a laptop lock with a key, you usually get two keys so you have one in reserve.

What are the advantages and disadvantages of a laptop lock with a combination lock?

If you like to remember codes, we recommend a combination lock. Usually there is a 4-digit code that you have to memorise in order to be able to open your lock again later.

There are 10,000 possible combinations for a 4-digit code.

Since you have a combination lock, you don't have to carry around additional keys, which can easily be lost or stolen.

  • Easy to install
  • No special keys required
  • No loss of a key
  • No additional key on your key ring
  • Imprinting of the numerical code
  • Code can be deciphered

What are the features of a laptop lock with a key and what are its advantages and disadvantages?

If you are a person who does not like to memorise numerical codes or is very forgetful, then a lock with keys is certainly a practical solution.

You can simply attach your key to your existing key ring. There is usually a spare key that you can keep at home or with your family for emergencies.

  • Easy to attach
  • Key only
  • No need to memorise a number code
  • Spare key available
  • Special keys required
  • Loss or theft of keys possible

Buying criteria: Use these factors to compare and evaluate laptop locks

In the following, we will show you which aspects you can use to decide between the many possible laptop locks.

The criteria you can use to compare laptop locks include:

In the following paragraphs, we will explain what is important in each of the criteria.

Cable material

A very important point is the material of the cable. In order to protect your laptop sufficiently, it is advantageous to use a high-quality cable.

For example, a simple plastic cable will not adequately protect your laptop because it can easily be cut. On the other hand, a thicker and stronger cable made of steel is not easily damaged.

Carbon steel is more cut-resistant than carbon steel

There are cables that offer effective protection through cut-resistant carbon steel with a separate protective sheath. In general, it is always good to choose steel, because steel is very robust. The cable is usually sheathed with vinyl or PVC. The smooth sheathing helps to prevent your laptop or other equipment from being damaged or scratched.

Cable length

Cable length is also an important factor when it comes to buying a laptop lock. A short cable will not allow you to secure a laptop anywhere, as a shorter cable will reduce the attachment range. Thus, a longer cable offers more choice for attachment. Most cables have a length of up to three metres.

Type of cable: Retractable cable Spiral cable Normal cable
Function: The retractable cable can be pulled out of the housing and also fully retracted again A spiral cable is usually about 10 cm short in its normal state and can be extended up to 2 m The normal cable can neither be retracted nor extended

Cables that can be retracted or extended are of course very practical, because you don't have a tangle of cables at the end. This is certainly a positive factor.

Cable thickness

The cable thickness or diameter should not be ignored.

A thicker cable is more durable.

The thicker the cable, the better and, above all, the safer the protection. If you buy a thicker cable, it is more difficult to cut the cable.

We recommend a cable diameter of at least 5.0 mm. The cables are available in various diameters. You can choose between a cable thickness of less than or more than 5.0 mm.

Closure type

The term lock type refers to whether the laptop lock can be opened with a numerical code or with a key.

As we have already learned above, there are of course some advantages & disadvantages that laptop locks with numerical codes or keys bring with them.

Compatibility / security slot

A laptop lock is not only compatible with different notebooks, but you can also use it to secure other devices. The following electronic devices can be secured with some laptop locks:

  • Tablet
  • iPad
  • Monitors
  • Projectors
  • Printers

Of course, not every lock can be used for all laptop models, so you have to pay attention to what kind of security slot is on the lock.

The most common locking mechanism is the T-bar locking head.

There is, for example, the Kensington security lock, which has a K on the lock. It is suitable for laptops that have an opening of approx. 3.0 x 7.0 mm. For this reason, you need to know what kind of opening your laptop has before you buy it.

Facts worth knowing about laptop locks

How do I attach a laptop lock?

Once you have bought your laptop lock, the next question is how to attach it. You will find a small opening on your laptop. Once you have found the opening, here is a short guide:

  1. You take the cable & wrap it e.g. around a table
  2. Then pull the lock through the anchoring hole
  3. The lock is plugged into the laptop opening
  4. Turn 90° to the left to anchor the lock
  5. The key is pulled out and stored safely
  6. Your laptop is now secured

When you buy a lock, it comes with instructions for use. If you have problems with it, watch videos on YouTube or read up on forums.

How secure is a laptop lock?

Of course, a laptop lock does not offer 100% protection, but it should serve as additional protection. It should also deter thieves, because if someone tries to tamper with the cable, the laptop is usually no longer usable and the thief has nothing to gain from it. So it is less interesting to steal a laptop with a lock than one without one.

For more security, you should take out insurance against theft and encrypt your confidential data with a password.

A more secure lock has a certain quality, of course. In addition, security depends not only on the laptop lock, but also on the quality of your laptop. If your device has a plastic opening and is not of a high quality and robust, this can reduce the security.
