Bottom Line

Has everything you need in a lock. A sturdy design that's versatile and practical. The best that Master Lock has to offer.

Pros

Smooth-turning locking mechanism allows you to choose your own combination. Sleek black coating prevents rust and tarnish; ideal for outdoor use. Lock feels durable. Shackle is spacious.

Cons

Some users say the reset key is flimsy, but you only have to use it to change the combination - a process that requires time and patience.

Bottom Line

Master Lock's quality and design in a set of two classic locks. The best choice if you're watching your budget.

Pros

Two locks for the price of one. Smooth operation and solid design. A classic model that stands the test of time. Versatile and easy to operate.

Cons

Comes with one combination that's not changeable.

Bottom Line

A durable lock, but it lacks the reliability you would expect for the higher price. Unless you need the long shackle, we recommend the Set-Your-Own model instead.

Pros

Versatile 2 1/4-inch shackle and solid brass construction. Durable feel. Easy to personalize. Resists the elements and corrosion.

Cons

Pricey. The numbers are small and hard to read. It's a bit stiff to turn and sometimes fails to work.

Bottom Line

A unique alternative to traditional models, but it has some issues. The word combination feature strongly appeals to some consumers.

Pros

Uses words instead of numbers, which some users prefer. Letters are large and easy to read. Combination is easy to change, and instructions are clear.

Cons

The design is somewhat bulky and heavy. Some owners have received faulty locks that fell apart.

Bottom Line

A decent choice if you want a value-priced, keyed lock.

Pros

A basic design with a traditional keyed mechanism. Sleek vinyl coating. Lightweight and easy to use; no combination to remember. Appealing price.

Cons

Construction is less rugged than others we tested, and the key occasionally jams. Has a tendency to rust when exposed to the elements.

Master Lock locks are the perfect choice when you need a versatile type of security. No matter what kind of lock you need, Master Lock almost certainly makes it. Standard Master Lock padlocks work well for residential, gymnasium, or school needs. They’re available as keyed or combination padlocks. Master Lock also makes lock boxes and locking cables. When you need locks for a business or industrial setting, Master Lock offers these items too. The extremely thick industrial padlocks are difficult to cut. The company even makes locks designed for particular styles of fence gates or doors. One of the newer designs in Master Lock locks is the ability to “set your own” combination. This makes it easier for you to remember the combination.
