Choose by your situation
| Situation | Model to consider | Main tradeoff |

| You lock an outdoor shed, gate, fence, storage unit or job box and want cut resistance | Master Lock M5XT Magnum keyed 2-pack | Physical keys to carry and possibly lose; featured offer at observation was a third-party seller; thinner rating record; live price hidden behind add-to-cart. |

Master Lock 1500T: the keyless locker pick
The Master Lock 1500T 2-pack suits students, gym members, employees and anyone securing indoor lockers or cabinets: two preset 3-digit dial locks opened by the same factory-set combination, so there are no keys to carry, copy or replace. The listing describes a metal body with a stainless steel cover, a hardened steel shackle that helps resist cutting and sawing, and an anti-shim mechanism that helps protect against shimming, in a 1-7/8 in. body that fits many locker hasps. It carried 4.6 stars across 6,268 ratings as Amazon's Choice with 5K+ bought in the past month, plus a Limited Lifetime Warranty line. Its limits are control and setting: the code is preset, not one you choose or reset; one shared code opens both locks, so anyone with the code opens everything; the listing positions it for indoor storage rather than outdoor exposure; and the live price sits behind the add-to-cart step with only a $12.01 Other-sellers rail visible — that rail is not the buybox price. The buybox observed was Amazon-direct: ships from and sold by Amazon.com.
Master Lock M5XT Magnum: the outdoor keyed pick
The Master Lock M5XT Magnum 2-pack suits sheds, gates, fences, storage units, tool boxes and job boxes: two keyed padlocks with two keys where both keys open all locks, so one key covers multiple doors. The listing describes Dual Armor construction — a laminated steel body with stainless steel and zinc outer parts — plus a Tough-Cut octagonal boron-carbide shackle, a 4-pin cylinder and dual ball bearing locking for increased pick and pry resistance, in a 2 in. wide body with a 3/8 in. shackle. It carried 4.7 stars across 262 ratings as Amazon's Choice with 50+ bought in the past month. Its limits are keys and evidence depth: keys must be carried and can be lost; the featured offer at observation came from third-party MaxWarehouse rather than Amazon directly (an Amazon-direct alternate row was also visible); the rating base is far thinner than the combo's; the warranty line is generic with details behind a link; and the live price sits behind the add-to-cart step with only a $28.88 Other-sellers rail and a $31.99 frequently-bought-together line visible — neither is the buybox price.
What to check before you pay
Confirm the exact variants — Master Lock 1500T in Black 2-pack (B00004SQLJ) and Master Lock M5XT Magnum 2-pack keyed-alike (B000WEKMM0) — and the live price, seller and delivery date, because both main buybox prices hid behind an add-to-cart step on 09/13/2026 (exact-variant sellers observed: Amazon.com direct for the 1500T; MaxWarehouse featured with an Amazon.com-direct alternate row for the M5XT). The M5XT page also lists a 1-pack swatch with no featured offers — that swatch is not the verified 2-pack variant. Either lock secures one hasp per lock; buy the 1500T for keyless indoor lockers, or the M5XT when the lock lives outdoors and cut resistance matters.
