Keyno is a small silver padlock that you can open by using a Bluetooth device. Once you download and install the Keyno application on your smartphone, you'll be able to flip open your padlock with one click. The lock’s made of heavy-duty, durable forged steel that won't break down easily when exposed to harsh weather conditions, so besides using it indoors, you can use it to lock up virtually anything outdoors. You can use the same smartphone to open multiple locks, and each lock operates by virtue of a small battery that'll last for up to two years. Therefore, you likely won't need to replace your locks frequently.

The Claim

When you use the Keyno padlock, you'll be able to quickly open a variety of locks without searching for the right key or having to remember a combination correctly. There are so many uses for this lock that making use of it will dramatically reduce the number of keys that you'll need to carry in your purse, backpack, wallet, or pocket. It can be used to lock up bikes, lockers, toolsheds, storage units, and supply closets, among other things. Since most people carry a smartphone on a daily basis anyhow, you likely won't find it difficult to remember to bring yours along in order to access your Keyno.

How It Works

To use Keyno, you'll need to download the corresponding application to your smartphone. When you want to open a Keyno lock, you must open the app, aim your phone at the lock, and click the appropriate button found within the application. With that click, your padlock will slide open. You won't need to be concerned that other individuals with the same app will be able to open your lock, as it'll only recognize your smartphone's distinct Bluetooth frequency.


  • Silver

    Each Keyno padlock is silver like many ordinary padlocks, so none of them will appear out of the ordinary when spotted. Hence, they're no more likely to attract the attention of a potential thief or trespasser than other locks are.

  • Compact

    These locks are also no bigger than most combination locks, so if you need to transport one or more from one place to another, it won't be difficult for you to carry them.

  • Secure and Durable

    The heavy-duty forged steel that Keyno padlocks are made from allows them to withstand a variety of weather conditions and yanking and pulling done in attempts to open them. Their secure, durable construction greatly increased the likelihood that your belongings will remain safe when locked up with ( or behind ) one of these locks.

Positive Points

  • Lighten Your Load

    If you currently carry around a bunch of keys that you use to open various locks, you'll be able to reduce your load by using Keyno. While one of these devices isn't appropriate for securing a home or car door, you'll likely be able to use one for most other things that you need to lock up. Instead of a handful of keys, you may be able to get away with carrying only a couple.

  • Can Use More Than One

    If you decide to make use of multiple locks, you won't need a new smartphone to open each one up. While each lock will only recognize the frequency of one smartphone, one smartphone's app can be used to control multiple locks.

  • Long-lasting Battery

    Each lock's small battery will last for up to a couple of years, so you won't need to frequently replace your padlocks.

Negative Points

  • Problems if Phone Broken

    While it's convenient that you can open these locks with a smartphone, you will run into problems if your phone is broken ( or lost ). Even if you install the Keyno app on another phone, your lock won't recognize the new phone's frequency, so you'll likely have to have it cut off.

  • Schools May Not Allow

    Some schools only allow a certain type of combination lock to be used on lockers, so if you attend one with this kind of rule, you'll have to forego using Keyno for that.


  • Keys

    Keys can feel heavy and make an irritating noise as you carry them, especially if you're carrying many. Plus, they aren't hard to misplace, and ones made of weaker material are capable of breaking inside a keyhole. If a piece of a key gets stuck inside a lock, it can be incredibly difficult to get out.

  • Combination Locks

    You'll have to remember your combination at all times when using one of these, which could be difficult if you're exhausted or sick. Furthermore, people who watch you open a combination lock may be able to figure out the combination and open it without your knowledge.
