Buying Guide

Match lock type to your laptop

Check whether your device uses a Kensington-style universal slot, a wedge-shaped slot, or requires a desk anchor before selecting a cable or wedge lock

Choose keyed vs combination

Keyed locks offer straightforward operation and replaceable keys in packs, while combination and resettable-code locks remove the need for physical keys but require remembering codes

Consider anchoring method

Look for locks that include an anchor plate or desk-anchoring option if you plan to secure devices on surfaces without built-in anchor points

Evaluate cable strength and build

Steel braided cables and reinforced lock housings resist cutting and leverage; verify cable thickness and construction in product specs when security is a priority

Factor in compatibility and portability

Slim and ultra-thin laptop designs may need wedge-slot locks or low-profile mechanisms, while multi-device users may prefer solutions that pair physical locks with software protection
