Padlocks may have been around for centuries, but they are still a great and flexible option for securing your stuff like bikes, sheds, lockers, gates… and the list goes on. However, not all padlocks are created equal. Some padlocks are far less secure to picking by savvy thieves and some are less secure against the outdoor elements. And then there is the issue of convenience and design.
When choosing a padlock, you want to make sure that it is the best one for your needs. There are three main factors when choosing the best padlock for your needs. 1. The locking mechanism. 2. The material and 3. The design. However, there are also other factors that contribute to finding the most suitable padlock. This article helps to outline these factors if you are in search for the best padlock. You can also check out this review of the best padlocks.
Locking Mechanism
There are two main types of padlocks- keyed and combination. These are traditional locking mechanisms. But there are also new kids on the block that use modern technology in their lock functions, namely bluetooth and biometrics. Each type of locking mechanism has its own benefits and drawbacks, so you need to decide which one is right for you.
Keyed Padlocks
A keyed padlock is equipped with a tumbler and pin mechanism. The spring-loaded pins within the lock are moved by the teeth and notches of the key.
Keyed padlocks obviously require a key to open them. The keys are usually small and easy to lose, so you should take care of them. Most keyed padlocks have a duplicate key when you purchase the padlock. If not, make sure you have a spare key/keys cut and stored securely.
Combination Lock Padlocks
Combination padlocks are a type of padlock where you must enter a specific sequence of numbers or letters in order to unlock the device. This sequence is usually set by the user and can be changed at any time. There are a few different types of combination locks, but they all work in basically the same way.
When you want to open a combination padlock, you typically first need to find the reset button. This is a small, circular button that is usually hidden on the back of the lock. Once you have located the reset button, you need to press and hold it down while turning the dials to the correct sequence.
Once you have entered the correct sequence, release the reset button and the lock should open.
Combination padlocks are great for securing things that you don’t want people to have access to, like a locker at the gym or a storage unit. They are also very resistant to tampering, so they can be a good choice for security purposes.
Bluetooth Padlocks
Bluetooth padlocks are a type of padlock that use Bluetooth technology to unlock. This means that you can unlock the padlock without needing to have the key with you. You just need to have your phone or other bluetooth-enabled device close to the lock. This can be really handy if you lose your key or if you want to share access to your padlock with someone else.
Setting up a bluetooth padlock is pretty easy. All you need to do is download the app for your lock and follow the instructions. The app will walk you through the process of pairing your device with the lock and creating a password. Once you have set up the lock, you can open it by simply clicking on the app and entering your password.
There are several benefits of using a Bluetooth padlock. Firstly, they are really easy to use – all you need to do is download the app and follow the instructions. Secondly, they are really secure – the locks use a four-digit password and 128-bit encryption to keep your belongings safe. Thirdly, they are really handy – you can unlock them without needing to have the key with you. Finally, they are affordable – Bluetooth padlocks start at around $20.
There are a few disadvantages of using a Bluetooth padlock. Firstly, there is the possibility that they could be hacked, although this is unlikely. And then there is the chance that someone has access to your phone whether with permission or not, and then has access to the app to control the lock. That’s why it’s important to add second layer security on your apps with passwords. Another potential weakness is that they can be drained of power, which can leave you stranded with a locked door if the battery dies. Another consideration is the design and materials used. Not all bluetooth padlocks will be as secure as their mechanical competition. And then of course, some bluetooth models can be more expensive than the traditional keyed versions.
Smart (WiFi) Padlocks
WiFi padlocks are related to their bluetooth cousins. They are also electronically controlled. However, these are connected devices that communicate across your network and even the internet. Typically this happens through the downloading of an app to your phone where you connect the device and enroll it. From their you would be able to set access codes and change them on the fly. This makes these a great for AirBnB type applications where access to a shared space like a closet or shed has to be granted and changed frequently and remotely.
Smart padlocks have the same drawbacks as the bluetooth options listed above.
Biometric Padlocks
One of the newer types of padlock on the market is the biometric padlock. This type of lock uses a fingerprint scanner to unlock the door. So, how does it work? First, you set up the lock by enrolling your fingerprint into the system. A small scanner on the padlock scans your fingerprint. The scanned image is converted into data that is used to unlock the door. When you want to unlock the door, you place your finger on the scanner and wait for the green light. If your fingerprint is recognized, the door will unlock. Biometric padlocks offer a good level of security for your belongings.
A biometric padlock has a couple of advantages over other types of padlocks. First, it is very secure. The fingerprint scanner can only be unlocked by someone who has the correct fingerprint. Second, it is very convenient. You don’t have to remember a password or carry a key with you.
Shackle
The shackle is usually the metal loop that opens to lock and unlock the padlock. It comes in a range of sizes and diameters to suit various demands. The key to a sturdy shackle is thickness and strength. The thicker the shackle, the more difficult it is to cut through.
The shackle is the most exposed element of a padlock. Padlock makers frequently use a robust material to keep people from injuring the shackle as part of their overall protection strategy. Brass, stainless steel, hardened steel, boron carbide, and molybdenum steel alloy are some of the many materials used in shackles.
Brass and stainless steel are lower grade options. They offer limited protection against impact although stainless steel shackles are rated for outdoor use because of their resistance to corrosion.
In the mid-range of shackles are those comprised of either hardened steel or hardened boron steel alloy. These metals undergo a heat treatment to create a hardened outer layer. Although tougher than conventional stainless steel, these both can still be susceptible to some power tools.
The most durable (and most expensive) materials for padlock shackles are boron carbide and molybdenum steel alloy.
The shackle type can be either open or closed. An open shackle is the typical style usually seen. The shackle is exposed above the padlock body. This makes it convenient to attach to and secure items. However, it makes is easier for thieves to cut through.
A closed shackle (also known as shrouded shouldered) is where the majority of the shackle is covered by the body of the lock. This means less of the shackle is exposed to attack. This can make all the difference. However, it does mean it can be more difficult and less convenient to use.
Material of Body
Another factor to consider when choosing a padlock is the type of material it is made from. We discussed the shackle material above, but the padlock body material is just as crucial. The most common materials are steel and brass. Steel is stronger but brass is more resistant to corrosion.
Home Depot recommends die-cast zinc, solid-steel bodies, and boron-steel shackles as they “offer superior cut and pry resistance.”
Size of Padlock
The size of the padlock can greatly impact the performance of the device. The lock should be large enough to fit the object you are securing, but cannot be too large that it is bulky and difficult to carry. A rule of thumb is to use the largest lock you can. It will be typically more resistant to breakage plus it’s size will be more of a deterrent.
Security Ratings
There are some industry standards that help making a decision about the security grade of a padlock. Most rating will be displayed on the padlock. Higher grade security padlocks will have earned ratings from trusted industry standards. These include LPCB, Sold Secure, the police approved Secured by Design and CEN (a European standard indicating minimum security and performance). General purpose locks will show the manufacturer’s own “security rating” guide on the packaging.
Weatherproof features
When you’re in the market for a padlock, my suggestion is to look for weather-resitant models. These will be ones constructed of brass , laminated steel, rustproof stainless steel or aluminum. Those with electrophoretic finishes or padlocks with polymer / plastic / rubberized covers also provide enhanced weather-resistance. Although you may not be planning on using your new padlock outdoors now, at least you could repurpose it in the future.
You can also check the salt spray test. Higher-end padlocks that are worth their salt (haha) in terms of weather-proofing may carry a salt spray rating. The higher the rating the longer the lock should hold up in adverse weather.
A keyhole cover can also help prevent the elements entering the sensitive moving parts of the lock mechanism.
Alarmed Padlocks
There are some specialist padlocks that have built-in alarms. These can be excellent for use on bikes for example, drawing instant attention to an attempted robbery. These alarms can pack quite a punch such as 110dB! Again, with the added features of an alarm, the lock itself often isn’t as strong as more expensive, simpler models.
Brand of Padlock
When it comes to most security-related devices, a basic rule is go for a trusted, reliable brand. It is no difference when it comes to padlocks. There are several established brands that are household names. Here are some:
- Master Lock. Master Lock probably has the greatest selection among all manufacturers and has some of the best, most reliable padlocks on the market.
- ABUS. ABUS has some very heavy duty options in it’s line.
- Stanley. This well-known tool manufacturer also has some very solid padlocks.
- Medeco.Medeco is big name in conventional locks and security that provides customizable, re-keyable padlocks.
- ASSA. Like Medeco, ASSA is a major name in locks and offers customizable, re-keyable padlocks.
- IglooHome. Igloohome offers some state-of-the-art smart, connected padlocks, safes and door lock solutions.
- BenjiLock is a leader in biometric padlocks and other locking devices.
The Final Score
When choosing a padlock, make sure to consider all of these factors so that you can find the best one for your needs: the material, size, locking mechanism, the shackle size and type. A rule of thumb is get the largest lock that allows you to secure your stuff. The more valuable your stuff, the more you should be willing to spend on a padlock. There are thousands of options, including modern electronic, smart padlocks on the market, but understanding what is the best option for your application will enhance the security of your valuable stuff.
