More and more users are now choosing combination locks to secure their personal belongs for residential, commercial or industrial applications. For electronic combination locks, the product can also be opened by physical key at some emergency situation, and you could also use smartphone APP, RFID card or fingerprint to unlock the door when you forget the password. When it comes to mechanical combination lock, it is difficulty to handle because the product does not support multiple way of unlocking.
In this article, we will discuss how to unlock a mechanical combination lock wen forget the correct code.
The first and easiest way people may think is to try the combination code. However, let’s take the 4-wheel combination lock as an example, there is 10,000 possible number combinations for this lock. Assuming you could do 10 tries per minute, it'll take at most about 17 hours. We think nobody will continue to try all these combinations one by one. In this situation, you may need to think about the most possible number you would use as the first number. As long as you have fixed the first number, the remaining three numbers will just have 100 possible combinations. You could write down these combinations and try them one by one till the get the correct password.
Obviously, to try the password will waste much time, therefore, to call a locksmith from local would be one solution, because they usually have professional tools such as hammers, chisels and prybars for break-in by force. The best way is to keep the password in somewhere for emergency situation, for example, you could put a longer number which include the correct number in your smartphone, PC, tablets or wallet in advance, then you could guess the correct code in short time.
