Is it the right lock for you?

A good pick if

  • You want to read the dials straight on while the lock hangs on the door
  • You change your code often: the SET switch makes it a quick job
  • You want a lock that is easy to spot in a row of lockers

Choose something else if

  • You need to lock a gate or a shed: pick a lock with a thicker shackle
  • You want a key as a backup: this lock has none
  • Your hasp is wider than 0.9 in (2.3 cm)

What buyers say about the Gym Locker Lock

4.5 out of 5 on 11,942 ratings. Reviews word for word, good and bad.

  • ★★★★☆

    Solid lock

    This is actually a decent lock. The dial has a nice feel, not loose, and not too hard to turn, each number has a nice click to it. The lock itself feels weighty and solid, and opens and closes easily. I have not found it necessary to change the combination on it yet, but it appears to be fairly straightforward. The entire lock is probably at the largest you'd want to go for a school locker as far as fitting into the latch, but it does fit. I would probably buy this lock again if I needed just an affordable combination lock that doesn't feel cheap and hollow.

    Well made lock, Easy to program your combination

    The lock is heavy and seems to be well built. The numbers on the combination dial are large and high contrast, making them easy to see even in dim light. The lock comes in a variety of colors. I got the orange one because of its high visibility. Programming is quick and easy--just open the lock, remove the small screw and cover on the bottom to access reset button, slide the button to the program position, then dial in a new combination. Slide the reset button back, then replace the cover and screw. Note that when you close the shackle, it does not automatically lock. Instead you must move the combination dials to make the lock secure. This is true of most locks of this type, which is different than the old style "dial" combination locks.

    A Great Lock and Easy Setup

    Used for a few weeks now and it been a great lock at the gym and no issues so far. Setup was easy as follow the instructions to get a screwdriver to unscrew the bottom panel, flip the switch, set up your combo, flip to switch again to save your new combo. I've had no issues so far for any malfunctions and its strong and holds up locking my belongings at the gym lockers.

    I'm the lock guy, so this is what you need.

    Returning it, but don't let that keep you from buying it. Because the problem I'm reporting is probably one in a million and I'm picky. The spring tension on some of the wheels isn't strong enough to hold the wheel in place and the combination can be easily bumped. But this lock follows the master lock 178 design and no they're not using ball bearings here, but it's working the same. When you attempt to pick this lock, you will be up against a huge challenge, because you're relying on an internal spring to apply a slight pressure on the combed shaft to allow Passage through the gates. Pulling the shackle only tightens the grip on the blocking bar, so it can't be picked, at least not conventionally. Only when the correct combination is dialed will the blocking bar be permitted to drop, allowing the ball bearings freedom to move. Furthermore, the fact that the shackle is short, notch locked and held deep in the body of the lock, means that the lock is much more resistant to Brute Force attacks such as twisting via a pipe wrench or pliers. The lock is resistant to shim attacks between the wheels of the dials as well, and prying the plastic cover off to have better access to the wheels, does you no good at all. Is it tough Under Fire? YES IT IS! Because the wheels are made of plastic, and burning or melting them only guarantees you'll never be able to open the lock, and underneath the plastic wheels is brass. In closing, for a cheap retro or chinese made replica, it's worth the money definitely, so five stars. It's very good and I really like the change code slide switch on the bottom, mine even come with a protective screw down cover plate to prevent accidental change of combination. It's a nice feature, but it's really not necessary because the change code switch takes some effort to snap it over to the change code position, but if you never plan to change the code once you set it, the protective cover plate is nice. Now that you've read my review, I will promptly return my lock as defective, while telling you to buy it, because you likely won't regret it. Special note, I'm hearing reports of RUST, so it MAY NOT BE GOOD FOR OUTDOOR USE!

    Strong and Bright

    Love it. I can see the orange bright anywhere, and I don't have to worry about losing a key. It is solid, and it deters crime!

    Combination Locks In

    Nice lock, once the combination is set you can lock it in. I have other locks where the combination was inadvertently changed which rendered it useless and then had to be cut off. Very nice strong design.
