Question 1

Which security slot does my laptop have — Kensington or NanoSaver?

Accepted Answer

Check your laptop's specification sheet or the manufacturer's website — the slot type is almost always listed under physical dimensions or security features. As a rule of thumb, most business laptops from Dell, HP, and Lenovo made in the last decade use the standard Kensington Security Slot (rectangular, approximately 5.5mm × 3.5mm). Ultraportables and newer thin-and-light models increasingly use the smaller NanoSaver slot. If you can't find the information, a 3-in-1 lock that ships with multiple anchor types is the safest purchase — it covers both standards plus the Wedge anchor used by Surface devices.

Question 2

Is a combination lock less secure than a keyed cable lock?

Accepted Answer

Generally, yes — keyed locks with pin tumbler mechanisms and restricted keyways are harder to defeat than combination locks. Combination locks are vulnerable to shoulder surfing (someone watching you enter the code) and, on cheaper models, to systematic brute-force attempts. That said, the practical security difference is modest for most office environments where opportunistic theft is the real risk. The more important distinction is whether the combination is resettable: a fixed-code combination lock is a genuine liability, whilst a resettable model lets you change the code if it's ever compromised.

Question 3

Can I use a Kensington cable lock on a Microsoft Surface Pro?

Accepted Answer

Not with a standard Kensington Security Slot lock — Surface Pro devices use a Wedge anchor port, which is a different physical standard. You need either a lock specifically designed for Surface Pro (such as the Kensington Keyed Cable Lock Surface Pro 3-8) or a 3-in-1 multi-anchor model that includes a Wedge anchor attachment. Be aware that the Surface Pro 3-8 lock is not guaranteed to fit newer Surface generations — always verify compatibility with your specific model before purchasing.

Question 4

What cable thickness do I actually need to resist bolt cutters?

Accepted Answer

For meaningful bolt-cutter resistance, look for hardened steel cable at 6mm diameter or above. Standard braided cables at 3–4mm can be cut with decent bolt cutters in seconds — they deter opportunistic thieves but won't stop a determined one. In practice, most office environments don't require bolt-cutter resistance; the visible presence of any cable lock is enough to redirect a thief to an easier target. If you're securing equipment in genuinely high-risk or publicly accessible spaces, prioritise cable gauge and hardened steel construction over price.

Question 5

Are cheap cable locks from unknown brands worth buying?

Accepted Answer

For low-risk environments, a budget lock from a lesser-known brand can be perfectly adequate — the deterrent effect is real regardless of brand. The risk with very cheap models (typically under 23 £) is inconsistent build quality: flimsy lock heads, thin cables that kink and fray quickly, and combination mechanisms that fail after moderate use. Brands like DICOTA, Mobilis, and HP offer budget-friendly options with more reliable quality control than generic no-name alternatives. We'd avoid completely unbranded locks for anything beyond very temporary, low-stakes use.

Question 6

How do master key systems work for IT departments managing multiple locks?

Accepted Answer

A master key system allows a single master key to open every lock in a fleet, whilst each individual lock also has its own unique key. This means an IT manager can access any secured device without needing to track dozens of individual keys, whilst employees still have personal keys for their own equipment. Kensington offers master key-compatible systems specifically designed for enterprise deployment. The trade-off is cost — master key systems sit firmly in the upper price tiers — but for organisations managing 20+ devices, the administrative saving is substantial.

Question 7

What's the most common mistake people make when buying a cable lock in 2026?

Accepted Answer

Buying the wrong anchor type for their device — by some margin. It's an easy mistake: you search "laptop cable lock", pick the best-reviewed option, and only discover at the desk that the lock head doesn't fit your security slot. Always identify your device's slot standard first (Kensington, NanoSaver, Wedge, or T-Bar) before selecting a lock. The second most common error is choosing a fixed-code combination lock over a resettable one — the price difference is minimal, but the security implications of being stuck with a compromised code are significant.
