Factors to Consider

Because Master Lock padlocks are plentiful and popular, choosing just one isn’t easy. You can, of course, go off our top 10 recommendations above, but there are still key factors to consider before choosing a Master Lock padlock.


What exactly do you need the lock for? Answering this simple question can narrow down your search drastically.

Not all padlocks are built the same even if a lot of them look the same.

Some padlocks are designed for items like lockers or backpacks, while others are designed for trailers or garages.

Key, Combination, or Neither?

Since padlocks come in a variety of styles, they can open differently as well.

Common ones are keyed or combination styles. If you know you can manage to keep up and locate a key, then it’s perhaps the simplest choice.

The combination is another go-to as it’s found throughout schools and gyms for locker security. You don’t have to go for the typical combination though as Master Lock creates padlocks with choose-your-own combos for numbers, letters, or even directional input.

If you want to take a modern approach, you can consider smart locks instead. These are designed to work with Bluetooth and app connectivity, allowing you to monitor your lock when you’re away.
