KeySmart SmartLock vs. Seekerity Smart Lock: Which Trackable TSA Lock Should You Buy?

If price is all that matters, KeySmart's SmartLock undercuts Seekerity's Smart Lock by roughly half. If you'd rather buy a lock built and sold specifically for the EU and UK, with VAT already included and no customs surprise waiting at your door, the Seekerity Smart Lock is the simpler purchase. Both do the same core job: a TSA-compliant lock with an Apple Find My tracker built into the body, so there's nothing separate to buy, charge, or forget to pack on your next trip.

Quick answer

• Price is the biggest gap between them. KeySmart's SmartLock lists at $29.99 (roughly €27–28 before exchange-rate swings, international shipping, or any import charges), while Seekerity's Smart Lock is €59.95, sold and shipped directly within the EU and UK with VAT already included.
• The lock mechanisms are genuinely different. KeySmart's SmartLock is a combination lock built around a flexible steel cable loop, while Seekerity's Smart Lock is a rigid metal shackle padlock — the cable is more versatile for straps, handles, and backpacks, while the shackle is the more familiar choice for zipper-to-zipper closures.
• Both are Apple Find My only, with no Android support, and on paper, KeySmart's 2-year warranty and 60-day return window both run longer than Seekerity's 1-year warranty and 30-day money-back guarantee.

What each lock actually is

Both products solve the same basic problem the same basic way: instead of buying a plain lock and a separate AirTag and remembering to move the tracker between bags, the Find My chip lives inside the lock itself. Where they differ is the brand behind it, the lock style, and the market each one is actually built to sell into.

KeySmart's SmartLock is the US travel-accessory brand's answer to the same idea, sold from its own US-based store at $29.99 for a single lock, with family packs (buy 3, get 2 free; buy 5, get 4 free) that push the per-lock price lower for groups or multi-bag households. It's a TSA-compliant combination lock: instead of a key, you set your own code by holding a reset button and entering a new combination. KeySmart describes it as built around a steel cable loop rather than a rigid shackle, which reviewers note suits a backpack strap or bag handle as well as a zipper pull. It runs on a single CR1632 battery, replaceable through the back cover, and the lock itself keeps working even if that battery dies — only the tracking stops. Setup is the same as any Find My accessory: hold the button until the LED flashes, then add it as an item in the Find My app.

Where the real differences are

Price and where you're actually buying from

On sticker price alone, KeySmart is the cheaper lock by a wide margin. What that price doesn't include, for a shopper in the EU or UK, is the rest of the buying experience: KeySmart sells from its own US store, and at the time of writing there's no dedicated storefront serving European customers directly — third-party international shipping or forwarding services exist for exactly this reason, which adds cost, time, and a layer of complexity that a direct EU/UK order doesn't have. Seekerity's price is higher, but it's the full price: VAT is included at checkout under the EU's IOSS scheme, and there's no customs bill waiting on your doormat weeks later. If you're comparing pure hardware cost, KeySmart wins. If you're comparing the total cost and hassle of actually getting the lock to your door in Europe, the gap narrows considerably.

Cable lock vs. shackle padlock

This is a genuine design difference, not just a style choice. A cable loop, like KeySmart's, can thread through a backpack strap, a duffel handle, or a zipper pull that a rigid shackle can't reach — it's the more flexible option if you're locking anything other than a standard two-zipper-pull suitcase. A metal shackle padlock, like Seekerity's, is the more familiar form factor for securing matching zipper pulls on a hard-shell or soft-shell suitcase, and tends to feel sturdier against someone trying to pry or cut it, though neither lock is designed to resist a determined, equipped thief. If most of what you're locking is a classic suitcase zipper, the shackle is the simpler fit. If you're also locking backpacks, duffels, or straps, the cable is more versatile.

Warranty and returns

This one is a straightforward point in KeySmart's favor: a 2-year warranty and a 60-day return window both beat Seekerity's 1-year warranty and 30-day money-back guarantee. If warranty length and return flexibility are your deciding factors on their own, KeySmart's terms are longer, full stop.

What's identical either way

Neither lock works with Android — both are built on Apple's Find My network and need an Apple ID, so this isn't a point of difference, just a shared limitation worth knowing before you buy either one. Neither has a biometric or fingerprint unlock feature, despite that claim appearing on some third-party roundups of similar products; neither official product page mentions one.

What neither lock actually solves

Both rely on Apple's Find My network, which reports a location only when another iPhone passes near the lock and relays it — not a live GPS or cellular signal of its own. That works well in airports, stations, and towns, and less well somewhere genuinely remote. Neither lock prevents theft or guarantees you'll get a bag back; both are a deterrent and an inspection-friendly way to close a zipper, with tracking that tells you where the bag was last seen, not that it's safe. A handful of KeySmart's own listed reviews (not reviews specific to the SmartLock itself — the product page currently shows reviews pulled from other KeySmart products) describe a battery cover that can be opened with a coin, which also disables tracking if removed, and one review mentions a thin cable that could be cut with side cutters. Worth knowing before you buy either lock: a determined attempt to defeat any travel lock, cable or shackle, is possible — the honest value of both products is deterrence and information, not a guarantee.

Which one should you buy

• You want the lowest possible price and don't mind ordering from a US store. KeySmart's SmartLock is roughly half the price of Seekerity's, and its bulk packs push that further for multiple bags or a family.
• You want an EU/UK-direct order with VAT included and no customs guesswork. Seekerity's Smart Lock ships as a normal EU/UK order with nothing extra to pay on delivery.
• You're locking backpacks, duffels, or straps as much as a suitcase zipper. KeySmart's cable loop is the more flexible shape for that.
• You want the longest warranty and return window on paper. That's KeySmart, at 2 years and 60 days versus Seekerity's 1 year and 30 days.
• You already own other Seekerity Find My accessories, or want to pair the lock with a second tracked item. Seekerity's Travel Essentials Kit bundles the Smart Lock with the Smart Tracking Card for €89.95 — €4.95 less than buying both separately, and one order instead of two from two different countries.

If you've decided you don't want tracking built into the lock at all — just a cheap, no-frills TSA lock — the honest comparison for that is covered in Smart Luggage Lock with Apple Find My: Is It Worth It Over a Regular TSA Lock?, which also looks at bolting a separate AirTag onto a plain lock instead.
