Best Gym Locker Padlocks UK

The Abus 158KC45 is our pick for most gym-goers. It runs a 4-wheel combination rather than the usual 3, giving far more codes for anyone watching over your shoulder to guess. Forget your own code and you're not locked out for good, since a master key opens it and you can reset a fresh combination afterwards rather than buying a new lock.

The Defender DFCombi20 is Squire's own value range, built with school and gym lockers specifically in mind. A 20mm die-cast body keeps it compact enough for a tight shackle gap, and the 3-wheel combination resets whenever you like, so you're never stuck with a factory code. It comes with a 5 year guarantee, generous for a lock at this end of the range. The body is smaller than the other combination locks on this list, so measure your locker's shackle gap before you buy if your gym still runs older, wider bars. It won't match the 158KC45 on shackle strength, but for a locker that's already watched by staff and CCTV, it doesn't need to.

The Squire CP30 steps up to a 4.5mm steel shackle inside a 30mm die-cast alloy body, noticeably thicker than the Defender's. The 3-wheel combination is recodable at any time, and Squire rates it weatherproof, which matters more than people expect in a changing room that's basically a sauna for half the day. There's no key override built in, so if you forget the code, you can't fall back on a spare key the way you can with the 158KC45. For most gym lockers, the extra shackle thickness over the Defender is worth that trade-off.

Combination locks aren't for everyone, and the Abus 64TI30 is our pick if you'd rather carry a key than remember a code. Its 30mm body is titalium, Abus's own aluminium alloy, so it's noticeably lighter than a steel padlock of the same size without giving up strength. The hardened steel shackle carries a NANO PROTECT coating built to resist the corrosion that steam and sweat cause over time, plus a paracentric keyway that makes picking harder. It's available keyed alike too, useful if you and a training partner share a locker or want one key across several bags. The trade-off with any keyed padlock stands here too: lose the key and there's no code to fall back on.

The Abus 64TI40 is the larger sibling of the 64TI30, with a 40mm titalium body, the same NANO PROTECT shackle coating and the same paracentric keyway. It's worth the size step up if your gym's older lockers take a wider bar than a 30mm padlock comfortably fits, and its security rating of 5 out of 10 is the highest of any lock on this list. Like the 64TI30, it comes in a keyed alike option. The trade-off is the same as any keyed lock: no code to fall back on if the key goes missing, so keep the spare somewhere you'll actually remember.
