Thumb Lock is a small padlock that you can open with just a push of your thumb. With it, you'll no longer have to remember combinations or keys—or try to pick your own lock because you've forgotten them. This padlock's memory scanner will store your unique thumbprint in its memory so that you'll always be able to open it up, and it'll store the thumbprints of up to seven more people, too. That way, you can give trusted friends, family members or employees the ability to open it.

How It Works

Once any thumbprint is programmed into your lock's biometric memory scanner (consult your instruction manual for more detailed programming instructions), the lock will recognize that thumbprint at any time. As a result, whenever you touch the center of your lock with the same thumb that you've used to program that lock, it'll immediately pop open. The same goes when you've programmed another individual's thumbprint into your lock. As long as they use the correct finger and touch the front instead of the back, it'll pop right open for them in the same way.


  • Compact

    The Thumb Lock is no bigger than a standard combination lock that a high school student would use on their locker, so it's not easily noticeable as a unique type of lock. The button that you push your thumb into to open the lock is also fairly inconspicuous, as it just looks like a decorative design feature. However, when the lock recognizes your thumbprint, a small green light will blink discreetly, letting you know you can open your lock successfully.

  • Two Shades Available

    When you obtain one of these locks, you'll have a choice between two shades: black and silver. You'll also have the option of getting two locks at once in a set, but both must be the same shade.

  • Steel Shackle and Casing

    Each of these locks has a hard steel shackle, and the body of each lock is encased in stainless steel, making it incredibly durable. One of them will likely last you for years, even if you happen to drop it on the ground from time to time. The shackle will also be extremely difficult for potential thieves to cut, no matter what type of knife they have.

  • Anti-Shim Mechanism

    All of the Thumb Locks are equipped with an anti-shim mechanism that will stop potential thieves from inserting something into a certain lock in order to pick it. Once a would-be thief sees that this will be a difficult task, they'll likely move away from your lock and move on to another that's easier to break into.

  • Damage Resistant

    Aside from being impact resistant, making it able to survive drops to the floor or ground, your Thumb Lock will also be water resistant and corrosion resistant. Therefore, you'll be able to use it outdoors without worrying about it malfunctioning due to rain or beginning to rust after long-term use. Even if your lock does get rained (or snowed) on, this won't affect the biometric memory scanner inside.

Positive Points

  • Can Use Almost Anywhere

    This padlock is tough enough to be used virtually anywhere indoors or out, such as on gym lockers, sheds, and storage cases that contain valuables. You'll also be able to use it to lock up your bike outside when you have to leave it unattended for a period of time. You might decide to get more than one if you're tired of moving your lock from place to place whenever you find a new use for it.

  • Good for Children

    This is an ideal lock for children to use, since they may forget the numerical combination for combination locks, and may lose the keys for padlocks that require them to open up. They may not understand how to unlock a padlock with a smartphone application, either. With the Thumb Lock, however, you can simply program their thumbprint into the lock and they can touch it with that same thumb whenever they want it to open. Since you're never without your thumb, there'll be absolutely nothing to remember.

  • Reduces Pocket Load

    If you're doing physical activities outdoors, it may be annoying to have to carry one or more padlock keys with you or keep your smartphone on you in order to use an unlocking app. Fortunately, when you've got a Thumb Lock, you won't need to carry anything in your pockets as you do outdoor activities, and you'll still be able to open the lock.

Negative Points

  • Schools May Not Allow

    Although a school may recognize that this type of lock is ingenious, some schools insist that students use a certain brand of combination lock as a general rule. Consequently, the Thumb Lock may not be permitted for use on lockers in some elementary, middle and high schools.

  • Won't Work With Gloves

    In order to open up this lock, you must have your thumb bare so that the lock can recognize your thumbprint. That means that if you're wearing mitts or gloves, you'll need to remove one of them to open your lock, which could be annoying during a cold winter. Along the same lines, you must also make sure your thumb that's programmed into your lock is free of dirt, or the lock may not recognize it.

Tips & Tricks

  1. Program Both Thumbs In

    If you think you might forget which thumb's print you've programmed into your lock, and you don't need all seven remaining spaces for friends or family members, just program both thumbs in. That way, no matter which thumb you press against your lock, it'll open for you anyway.

  2. Set Up Emergency Access

    Even if you don't want to program the thumbprints of many friends, family members or employees into your lock, it might be a good idea to program at least one other person's thumbprint in. In the event that you ever find you can't use your thumbs, due to some sort of injury, they'll be able to open your lock for you. If you've got a child who uses the Thumb Lock, you might also want to program your thumbprint into it, so you can gain access, if necessary.


  • Don't Submerge In Water

    Although this padlock is water resistant, so you can expose it to rain and snow, it's not 100 percent waterproof. For this reason, you shouldn't immerse it completely in water, or its internal mechanisms, external appearance or both may end up damaged. If you want a lock to use inside your pool or under the water in some other location, you should look for a completely waterproof one.

Save Time

When you decide to use the Thumb Lock, you'll never have to waste valuable minutes trying to pick your own lock because you've forgotten your combination, key or smartphone. You'll always be able to get into your lock in seconds, which will reduce the chances that you'll be late for important activities on your schedule.
