Kensington Dell Laptop Lock - N17 Keyed Dual Head Laptop Lock for Wedge-Shaped Security Slots Found on Dell Devices plus Additional T-Bar Lock for Devices with the Kensington Security Slot (K67995WW), black, silver

Numbers on a box mean very little when you're trying to secure a £65.49 Dell laptop in a busy open-plan office. I've tested enough laptop locks over the years to know that the real questions are simpler and more brutal: does it actually hold, does it work with your specific machine, and is it worth the money compared to just buying a cable tie and hoping for the best? The Kensington K67995WW , the N17 Keyed Dual Head Laptop Lock , tries to answer all three by doing something genuinely clever: shipping with two different lock heads in the same box so it covers both Dell's wedge-shaped N17 slot and the standard Kensington Security Slot found on pretty much everything else.

I've been using this lock across several weeks of daily office and co-working space use, testing it on a Dell XPS 15, a Dell Latitude 5540, and a non-Dell ThinkPad E14 (just to see how the T-bar head performs in the wild). The 4.4-star average from 386 suggested I was looking at something genuinely solid rather than a marketing exercise, and for the most part that reputation holds up. But there are a few things worth knowing before you hand over your money , particularly around the cable construction and the key management situation , so let's get into it properly.

Bottom line up front: this is a well-thought-out, dual-compatibility lock that solves a real problem for Dell users without forcing you to buy two separate products. The build quality is good enough for daily professional use, the dual-head system works as advertised, and the price sits in a reasonable place for what you're getting. It's not perfect , the cable could be beefier and the key system is basic , but as a practical security solution for mixed Dell and standard-slot environments, it earns its place.

The cable loop at the anchor end is a standard lasso-style design that tightens around a desk leg, radiator pipe, or fixed anchor point. It's not the most sophisticated anchoring system on the market , some higher-end locks use a dedicated anchor plate , but for most office scenarios it does the job without requiring you to drill anything into the furniture. The overall weight is light enough that you won't notice it in a laptop bag, which matters if you're carrying this between sites.

Kensington rates this lock as part of their N17 series, which is specifically designed to address the compatibility gap that emerged when Dell started shipping laptops with the wedge-shaped slot instead of the traditional round Kensington slot. That's a pretty significant engineering decision on Dell's part that left a lot of IT departments scrambling, and this lock is essentially Kensington's answer to that problem.

The keyed mechanism is worth noting because Kensington has made a deliberate choice here over combination locks. Combination locks sound convenient until you're in a hurry, the lighting is bad, or someone's watched you enter the code over your shoulder. A keyed lock is faster to operate once you're used to it, and the two-key inclusion means you can keep a spare somewhere sensible rather than being completely locked out if you lose one. The key profile itself is a proprietary Kensington design, which is both a security feature (harder to duplicate at a high street key cutter) and a mild inconvenience if you do lose both keys.

The 1.8-metre cable length is another practical decision that I appreciate. Shorter locks , some budget options come in at 1.2 metres , can be genuinely awkward in real office environments where the anchor point isn't directly next to where you're sitting. 1.8 metres gives you enough slack to loop around a desk leg and still have the laptop sitting comfortably on the desk surface without the cable pulling at the port. And the lasso anchor design means you can attach it to almost any fixed object without needing dedicated hardware installed , useful in co-working spaces where you can't modify the furniture.

The PVC cable coating deserves a mention too. It's not just cosmetic , it prevents the cable from scratching desk surfaces and laptop chassis as it moves around during the day. After several weeks of daily use I haven't seen any significant wear on the coating, and the cable itself shows no signs of kinking or deforming even after being coiled and uncoiled repeatedly in a bag.

On the Dell XPS 15 (which has the N17 wedge slot), the wedge head engaged cleanly and positively. There's a satisfying click when it locks, and the head doesn't rattle or shift when the cable is under tension. I tested this by deliberately tugging the cable at various angles , straight out, sideways, upward , and the head stayed put without any sign of the slot deforming or the head working loose. On the Dell Latitude 5540, same result. The fit felt engineered rather than approximate, which is what you want from a security product. A loose-fitting lock head is worse than no lock at all because it gives false confidence.

Switching to the T-bar head for the ThinkPad E14 was straightforward , the heads swap out easily , and the T-bar engaged the Kensington Security Slot with the same positive click. No play, no rattle. I left the lock engaged overnight in a co-working space (with permission, obviously) and came back to find everything exactly as I'd left it, which is the most basic test of all and one that some cheaper locks actually fail due to the head gradually working loose under repeated vibration.

The cable itself is the one area where I have a mild reservation. At 4mm diameter, it's adequate but not exceptional. I've used Kensington's higher-end locks with 6mm cables and the difference in confidence is noticeable. A determined person with the right tool could defeat this cable, but that's true of most locks in this category and below. For the intended use case , deterring the opportunistic thief in a coffee shop or open office , 4mm is fine. Just don't leave this as your only security measure if you're in a genuinely high-risk environment.

Key operation is smooth and consistent. I tested locking and unlocking probably fifty times across the testing period and never had a sticky cylinder or a key that felt like it was fighting me. That sounds like a low bar, but I've used budget locks where the cylinder gets stiff after a few weeks of use, so it's worth confirming. The two included keys are identical and both worked perfectly throughout testing.

The lock heads themselves are where the quality really shows. The N17 wedge head has a precise, machined feel to it , the tolerances are tight enough that it engages Dell's slot without any slop, but not so tight that it's difficult to insert or remove. Compare this to some third-party Dell-compatible locks I've tried where the head is clearly a slightly-off approximation of the slot geometry, and you can feel the difference immediately. Kensington has clearly done proper engineering here rather than just eyeballing the dimensions. The T-bar head is similarly well-made, with the bar itself showing no sign of bending or deforming under the lateral forces you'd expect from a cable under tension.

The lasso anchor loop is reinforced at the point where it meets the cable body , this is a stress concentration point that cheaper locks often get wrong, leading to premature failure. Kensington's implementation uses a proper crimped metal sleeve rather than just a cable loop, and it shows no signs of fatigue after repeated use. Honestly, for a product in the lower mid-range price bracket, the build quality punches above its weight. You're not getting the ultra-premium feel of a Kensington MicroSaver 2.0 or a Targus DEFCON, but you're getting something that feels like it'll last several years of daily professional use without falling apart.

The head-swapping mechanism is worth explaining because it's not immediately obvious from the product photos. The two lock heads aren't permanently attached to the cable body , they clip on and off via a simple but secure mechanism. Swapping heads takes about ten seconds once you know what you're doing, and the connection between head and cable body is solid enough that I never worried about the head detaching accidentally during use. If you're primarily a Dell user, you'll probably just leave the N17 wedge head attached permanently and forget the T-bar exists. But if you're in an IT support role managing multiple device types, the ability to use one cable with two different heads is genuinely useful.

Key management is the one area where ease of use could be improved. Two keys is the minimum , I'd personally prefer three, because losing both keys means you're either calling a locksmith or accepting that your laptop is now permanently tethered to a desk. Kensington does offer a key registration service where you can order replacement keys if you have the key number, which is printed on the key itself. That's a sensible system, but it does mean you need to keep a record of that number somewhere safe. Worth photographing the key number when you first get the lock and storing it in your password manager or similar.

Daily use friction is minimal. The cable is flexible enough to coil neatly when not in use, the lock body is compact enough not to be in the way when you're working, and the key doesn't need to stay in the lock during use , you pocket it and get on with your day. One small thing: the cable can occasionally catch on desk edges if you're moving the laptop around while locked, but that's a consequence of the cable length and anchor position rather than a design flaw. Just something to be aware of in tighter workspaces.

The T-bar head covers the Kensington Security Slot standard, which is found on an enormous range of laptops from Lenovo, HP, Acer, ASUS, and others, as well as older Dell models. It also works with many desktop monitors, docking stations, and other peripherals that include a Kensington slot. So if you're running a mixed environment , say, Dell Latitudes for most staff but a few ThinkPads or HP EliteBooks in the mix , this single lock covers all of them. That's a genuinely useful proposition for IT procurement teams who want to standardise on one lock SKU.

What it won't work with: Apple MacBooks (which have no security slot of any kind), very thin ultrabooks from any manufacturer that have omitted the security slot to save space, and any device using a non-standard proprietary slot that isn't the N17 or Kensington standard. It's also worth noting that this is a keyed lock, not a combination lock, so if your organisation has a policy of combination-only locks (some do, for key management reasons), this isn't the right product regardless of compatibility.

One more compatibility note: the lasso anchor loop will work with any fixed object with a diameter that fits through the loop , desk legs, pipes, handles, cable management rails. The loop opens wide enough to accommodate most standard desk leg profiles, but if you have unusually thick desk legs or want to anchor to a wall-mounted bracket, measure first. In practice I've never encountered a standard office desk that the lasso won't fit around, but it's worth knowing the limitation exists.

The second scenario is the individual professional who works across multiple locations , office, co-working spaces, client sites. If you're carrying a Dell laptop and occasionally using borrowed machines or hot-desking on non-Dell hardware, having both heads available means you're covered regardless of what slot the machine has. I used this exact scenario during testing, and the ability to swap heads in ten seconds without any tools is more useful than it sounds when you're in a hurry to secure your kit before grabbing a coffee.

Students in university libraries and study spaces are another strong fit. University environments are high-risk for opportunistic laptop theft , you step away from your desk for five minutes and your machine is gone. A visible cable lock is a strong deterrent in these settings because opportunistic thieves want easy targets, not ones that require time and noise to defeat. The 1.8-metre cable gives enough reach to anchor to most library desk furniture, and the compact form factor means it doesn't add significant weight to a student's already-heavy bag.

Where this lock is less suited: genuinely high-security environments where you need hardened protection against determined attackers. If you're securing a machine containing sensitive government or financial data in a location with a real physical security threat, you want something with a thicker cable, a hardened anchor plate, and ideally an alarm function. The K67995WW is a deterrent lock, not a vault. That's fine for 95% of use cases, but worth being honest about for the 5% where it isn't.

Against more expensive options in Kensington's own range , the MicroSaver 2.0 or the ClickSafe series , the trade-off is primarily cable thickness and anchor system sophistication. Premium locks come with 6mm cables and dedicated anchor plates that are significantly harder to defeat. If you're in a high-risk environment, that extra investment is justified. But for typical office and co-working use, the K67995WW's 4mm cable and lasso anchor are genuinely adequate, and you're saving a meaningful amount of money.

The 4.4-star rating from 386 is a useful data point here. That's a solid sample size and a high average, which suggests that real-world buyers are finding the product delivers on its promises. The most common complaints in the reviews relate to key management (losing keys, wanting more spares) and occasional compatibility questions about specific Dell models , neither of which is a fundamental product flaw. The praise consistently focuses on the dual-head system working as advertised and the build quality feeling premium for the price. That tracks with my own testing experience.

For IT procurement specifically, the value case is even stronger when you factor in the operational benefit of standardising on one lock model. The time saved not managing two different lock SKUs, not training staff on two different lock types, and not dealing with the wrong lock being sent to the wrong device adds up quickly in larger organisations. At this price tier, it's a sensible choice that doesn't require budget approval from three levels of management.

The Targus DEFCON N-KL is a solid lock that handles the N17 slot well, but it's a single-head design , you get the N17 wedge head and that's it. If you have any non-Dell devices in your environment, you need a second lock. It's also priced similarly to the K67995WW, which makes the Kensington's dual-head approach look like better value for mixed environments. The Targus cable is slightly thicker at 5mm, which is a genuine advantage in terms of cut resistance, and the build quality is comparable. But for most buyers, the flexibility of two heads outweighs the marginal cable thickness advantage.

The Kensington MicroSaver 2.0 is a premium single-head lock with a 6mm cable, a hardened anchor plate option, and a more sophisticated cylinder mechanism. It's noticeably more expensive and only covers the standard Kensington Security Slot , no N17 wedge head. If you have a Dell with the N17 slot, it simply won't work. For non-Dell users who want the best possible single-head lock, the MicroSaver 2.0 is excellent. But for Dell users or mixed environments, the K67995WW is the more practical choice despite the thinner cable.

The complaints are worth examining too, because they're instructive about who might not get on with this product. Key management comes up repeatedly , people losing keys and finding the replacement process slow, or wishing three keys were included rather than two. This is a legitimate gripe, and if you're managing locks for a large team, the two-key limit does create administrative overhead. A handful of reviews mention compatibility confusion , buyers who didn't check whether their specific Dell model had the N17 slot before purchasing and found the wedge head didn't fit their older Dell with a standard Kensington slot. That's a buyer research issue rather than a product flaw, but it's worth flagging because it's clearly a common source of frustration.

A small number of reviews mention the cable feeling thinner than expected, which is fair , 4mm is adequate but not impressive, and if you've used premium locks before, the step down in cable heft is noticeable. Nobody in the reviews reports an actual security failure (lock defeated, cable cut), which is reassuring, but the cable thickness concern is real and worth acknowledging. Overall, the review profile is that of a product that does what it says, at a fair price, with a couple of minor operational limitations that are worth knowing about in advance.

The limitations are real but manageable. The 4mm cable is adequate for deterrence but not impressive for cut resistance , if you're in a genuinely high-risk environment, step up to a thicker cable. The two-key inclusion is the minimum rather than generous, and key management needs to be taken seriously from day one. And the compatibility question around which Dell models actually have the N17 slot is something you need to check before buying rather than after. None of these are dealbreakers, but they're worth knowing.

I'd score this a solid 7.5 out of 10. It's not the most impressive piece of hardware I've tested, but it solves a real problem well, it's built to last, and it's priced fairly for what it delivers. The 4.4-star community rating is deserved. If you're a Dell user who's been frustrated by the N17 slot compatibility issue, or an IT manager who wants one lock SKU that covers multiple device types, this is the one to buy.
