Cable Locks Price Comparison 2026
Compare 372 cable locks from Kensington, Targus, and more. Find the best price across top UK retailers and secure your laptop or device today.
Cable locks occupy a curious corner of the security market: unglamorous, often overlooked, yet absolutely essential the moment a laptop goes missing from a hot-desking office or a university library. We've analysed 372 products across this category, and the range is striking — from bare-bones options at 7 £ to enterprise-grade locking stations pushing well past 41 £. Most buyers, however, will find everything they need somewhere between those two extremes.
Kensington dominates this space with 125 listed products, and for good reason. Their NanoSaver and ClickSafe systems have become the de facto standard in UK offices, compatible with the Kensington Security Slot found on the vast majority of business laptops and monitors. That said, dominance doesn't always mean best value — Compulocks, StarTech.com, and DICOTA all offer solid alternatives, often at significantly lower average price points. HP and Mobilis in particular punch well above their weight for straightforward, no-fuss laptop security.
The real split in this category isn't between brands — it's between keyed locks and resettable combination locks. Keyed models (pin tumbler mechanisms with restricted keyways) offer stronger resistance to picking and are preferred by IT departments managing fleets of devices. Combination locks trade a little security for convenience, which suits mobile professionals who'd rather not carry yet another key. If you go the combination route, make absolutely sure the model is resettable — fixed-code locks are a liability if the sequence is ever compromised. For wider physical security needs, our padlocks category and safes range are worth a look alongside cable locks.
One detail that catches buyers out: anchor compatibility. A lock designed for the standard Kensington Security Slot won't fit a Surface Pro's wedge anchor port, and vice versa. The 3-in-1 models — which ship with T-Bar, Nano, and Wedge anchors — solve this elegantly for mixed-device environments. If your organisation also relies on smart card or biometric access, pairing a cable lock with solutions from our fingerprint readers category makes for a robust layered approach. Cable diameter matters too: anything below 4mm braided steel is fine for deterrence, but if bolt-cutter resistance is a genuine concern, look for hardened steel cables of 6mm or above.
How to Choose the Right Cable Lock for Your Device
Not all cable locks are created equal — and the wrong choice can leave you with a perfectly good lock that simply won't fit your laptop. The key decisions come down to slot compatibility, locking mechanism, and cable construction. Here's what actually matters.
Anchor compatibility with your device's security slot
This is the single most common purchasing mistake. Before anything else, identify which security slot your device has. Most business laptops use the standard Kensington Security Slot (roughly 5.5mm × 3.5mm rectangular opening). Ultraportables and tablets increasingly use the smaller NanoSaver slot. Microsoft Surface devices use a Wedge anchor. If you're unsure, check your device's spec sheet — buying the wrong anchor type means the lock is simply unusable. Multi-anchor 3-in-1 models cost a little more but eliminate the guesswork entirely, making them the sensible choice for mixed-device offices.
Keyed vs. resettable combination — matching the mechanism to your workflow
Keyed locks (pin tumbler mechanisms) are harder to pick and preferred for high-security environments. The trade-off is key management: losing the key is a genuine problem, especially with restricted keyways that prevent unauthorised duplication. Combination locks are more convenient for individuals who move between locations frequently. The critical caveat: only buy a resettable combination model. Fixed-code locks cannot be changed if the sequence is compromised or shared accidentally — a real vulnerability in shared workspaces. IT managers overseeing multiple devices should also consider master key-compatible systems, which allow a single key to open an entire fleet.
Cable gauge and construction — deterrence vs. genuine cut resistance
A thin braided cable at 3–4mm will deter opportunistic theft — someone isn't going to produce bolt cutters in a Starbucks. But in higher-risk environments (university campuses, open-plan offices with public access), you want hardened steel cable at 6mm or above. Braided steel offers flexibility and is easier to route around desk legs; solid hardened steel is stiffer but significantly more resistant to cutting tools. Don't be fooled by a heavy-looking lock head on a flimsy cable — the cable is almost always the weakest point.
Cable length and workspace practicality
Standard cables run between 1.5m and 1.8m, which suits most desk setups. Compact travel locks often drop to 0.6m–1.0m to save weight — fine if you're anchoring to a desk leg directly beneath you, awkward if the nearest fixed point is further away. Think about your actual workspace before defaulting to the shortest option. Conversely, an unnecessarily long cable creates slack that can itself be a vulnerability, giving a thief more leverage to work with.
Single-device lock vs. peripheral locking kit
If you only need to secure a laptop, a standard single-head lock is sufficient. But open-plan offices often need to secure monitors, docking stations, and peripherals too. Kensington's Desktop & Peripherals Locking Kit 2.0 addresses this with multiple anchors and cables in one package — more cost-effective than buying separate locks for each device. For organisations rolling out security across dozens of workstations, the per-unit cost difference between a basic lock and a full kit becomes significant at scale.
Portability weight for mobile professionals
If the lock lives permanently on a desk, weight is irrelevant. If it travels daily in a laptop bag, it matters considerably. Lightweight combination locks under 150g add negligible burden; heavier keyed locks with thick cables can reach 300–400g. The Kensington Slim series is specifically engineered for portability without sacrificing the NanoSaver slot compatibility that ultrabook users need. Check the product weight in the spec sheet — marketing terms like "slim" and "portable" aren't always consistent across brands.
- Budget deterrent (From 7 £ to 19 £) : Entry-level locks from Nedis, DICOTA, Mobilis, and HP. Thin braided cables, basic combination or keyed mechanisms, standard Kensington slot compatibility. Perfectly adequate for low-risk environments — a university library, a quiet office — where opportunistic theft is the main concern. Don't expect bolt-cutter resistance at this price point.
- The sweet spot (From 19 £ to 31 £) : Where most individual buyers should be looking. Kensington's Slim Resettable NanoSaver and Universal 3-in-1 Combination Lock sit here, offering resettable combinations, multi-anchor compatibility, and decent cable construction. Lenovo's own-brand locks also appear in this range. Good balance of security, convenience, and portability.
- For the security-conscious (From 31 £ to 41 £) : Kensington ClickSafe 2.0, StarTech.com models, and Compulocks options occupy this tier. Expect thicker cables, restricted keyways, stronger lock heads, and better build quality overall. Suited to IT managers, frequent travellers, and anyone securing genuinely valuable equipment. The step up in cable construction is noticeable.
- Enterprise and specialist (Over 41 £) : Locking stations, master key systems, and multi-device kits from Kensington and Targus. Targus's average sits around £273 and Kensington's fleet-management solutions push considerably higher. Designed for corporate IT procurement rather than individual purchase — the per-unit cost makes sense only when managing dozens of devices simultaneously.
Top products
- Kensington Keyed Cable Lock Surface Pro (3-8) (Kensington) : The go-to choice for Surface Pro users — purpose-built Wedge anchor compatibility makes it a rare find in a market dominated by standard Kensington slot locks. Solid keyed mechanism, but verify your Surface generation before buying; it's not guaranteed to fit models beyond the Pro 8.
- Kensington ClickSafe 2.0 3-in-1 Keyed Laptop Lock (T-Bar, Nano & Wedge Anchors) (Kensington) : The most versatile option in the top 15 — three anchor types in one package means it works across virtually any device in a mixed-hardware office. Premium price is justified if you're switching between laptops, tablets, and monitors. Overkill if you only have one device with a standard slot.
- Kensington Universal 3-in-1 Combination Lock Resettable (Kensington) : Our pick for the best all-round value in this category. Resettable combination, multi-anchor compatibility, and a price that sits squarely in the sweet spot. The combination mechanism won't satisfy high-security requirements, but for the vast majority of office and travel use cases, this is the one to buy.
- MASTER LOCK 8229EURDPRO cable lock Black 0.9 m (MASTER LOCK) : The budget outsider — Master Lock brings genuine pedigree to a very accessible price point. The 0.9m cable is short, which limits workspace flexibility, but for a fixed desk setup or travel use where you're anchoring close to the device, it's a credible and well-built option. Don't expect NanoSaver compatibility.
- Kensington Desktop & Peripherals Locking Kit 2.0 (Kensington) : The only product in the top 15 designed to secure an entire workstation rather than just a laptop. Multiple anchors and cables cover monitors, docking stations, and peripherals in one kit. Expensive relative to a single lock, but far cheaper than buying separate locks for each device — the maths works out for anyone with a full desk setup.

Frequently Asked Questions
Which security slot does my laptop have — Kensington or NanoSaver?
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.
Is a combination lock less secure than a keyed cable lock?
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.
Can I use a Kensington cable lock on a Microsoft Surface Pro?
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.
What cable thickness do I actually need to resist bolt cutters?
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.
Are cheap cable locks from unknown brands worth buying?
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 19 £) 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.
How do master key systems work for IT departments managing multiple locks?
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.
What's the most common mistake people make when buying a cable lock in 2026?
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.
