If you own a laptop, then it’s probably one of your most prized possessions. To protect it against theft and keep it secure when you are out working in different locations, think about investing in a laptop lock.

Like leaving your bicycle behind and locking it up, a laptop lock does the same when you’re working in a coffee shop or out in a remote location. The product comes in different shapes and sizes and secures not only your laptop, but other electronics as well. To help you find the perfect one, read on and discover the best laptop locks on the market.

Discovering the Best Laptop Locks

When searching for the ideal lock for your laptop, consider these key factors:

  • Locking Mechanisms: Some locks come with keys, and there are also combination locks. Both of these come in various styles. Your preference will depend on the security level that you’re looking for and how often you take your laptop on the go. A combination lock might also be more suitable for you if you decide to use it for other things like your keys, tablet, and docking station.
  • Compatibility: You might already know what a Kensington security slot is. It’s found in most laptops, but not all brands have them. Some laptop locks are only compatible with devices that feature this slot, so be sure to double-check the lock with the brand of your laptop. There are also universal locks that work without a security slot.
