More on Padlocks

When it comes to padlocks, it’s also possible to find combination locks – which do not utilize keys at all. Instead, the lock is opened when the user places the right 3 or 4 digit code into the body of the lock by turning the inbuilt wheels. These padlocks are often used on luggage, on laptops, and on lockers and come in a wide variety of sizes and designs. They have also gained popularity due to the lack of a key – which is often seen to be a burden to carry around. External keys can be lost, or can simply be unpractical to carry around.
