Factors to Consider When Buying a Master Lock

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.

Getting the wrong one may render the lock useless for your needs. For instance, if you’re looking to secure your luggage, you’d require a luggage-specific lock that’s the right size to fit on a bag. So, understand where the padlock will be before selecting one.

Key, Combination, or Neither?

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

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

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.


Making the Decision

Master Lock products are a great way to protect your belongings. If you want, take a look at our top pick, the Master Lock 141D Covered Aluminum Keyed Padlock.

It comes with two color-coded keys to match the lock so you’ll always know which key to use. The keys turn with ease as well.

This is known to last a long time thanks to the reliable aluminum construction and hardened steel shackle. With its four-pin cylinder and dual locking lever, the padlock does enough for light duty security whether you’re protecting a locker or an entry like a gate.
