But for those who try, our patented Hidden Pin™ technology is designed to defend against common picking techniques, thwarting attempts to pick the lock.

Frequently Asked Questions

1. How do laptop locks work?

The two most used locking options are our traditional keyed locks and combination locks, which are compatible with 99% of laptops, projectors, printers, and monitors with security lock slots.

For light and this laptops and tablets that are too slim for a standard lock slot, Kensington has designed a range of locks built to our tough standards that fit perfectly to secure these ultralight and mobile devices.
2. What is a security slot on a laptop?
3. Are laptop cable locks universal?
4. How do you open a laptop lock?

There are different types of laptops locks depending on the security slot type (standard T-bar, nano, or wedge-shaped) and lock type (Combination or keyed). Older technology like T-bar or standard locks required the user to align the lock slot with the T shaped cleat on the locking head and the turn the key to lock or unlock. As devices get thinner and lighter locks have evolved. With the introduction of nano and wedge-shaped slots the new locking mechanisms opens the locking cleats inside the slot to lock and closes them to unlock.
5. Do laptop locks really work?

Laptop locks are the first line of defense against device theft. They engage on the lock slot with one purpose, to lock the device from an anchor point designed to withstand pulling, tension, cut, humidity and more. Kensington locks use materials that are highly effective against cutting attempts, with the flexibility to anchor our cable locks to a desk, table, or other attachment point and with strong keyed or combination lock heads to satisfy every user needs.
