When it comes to the security of your belongings, combination locks are one of the most popular options. But did you know that they can have repeated digits?
Can Numbers Repeat in a Combination Lock?
Yes, if you’re wondering if numbers can repeat in a combination lock, the answer is yes. Generally, combination locks have three or four digits, with each digit ranging from 0 to 9. It’s common for the combination to use a series of three or four unique numbers, but some locks will also allow for repeating digits. This means that the first and third digits can be the same number, or the second and fourth digits can be the same.
The probability of a combination lock having a repeated digit is about one in 10. This means that for every 10 locks, one will have a repeating digit.
However, not all combination locks are the same. Some locks will have a higher likelihood of having a repeated digit than others. For example, locks that are made by the Master Lock company are known for having a higher likelihood of having a repeated digit.
