1. combination locks and how they work

Although there are several types of combination locks, they all have dials that are used to open the lock. These dials are usually numbered. Each dial is attached to a pin or other internal locking mechanism. The associated locking mechanism is disengaged when you turn a dial to the correct number. The combination lock will only unlock if all of the dials have been turned to the correct position. Some combination locks can also be opened with a key. In other words, you can either turn the dials to the precise position or insert and turn a key to open them.

2. Combination locks’ problem

Combination locks have the biggest flaw: they can be cracked by trial and error. For example, if a combination lock has three dials, each numbered zero through nine, the total number of possible combinations is only 720. While this may appear to be adequate protection against cracking, a determined burglar could certainly figure out the proper combination in less than an hour.

Some combination locks, of course, have more than three dials. The more dials it has, the more difficult it is to figure out through trial and error. Regardless of how many dials the lock has, a burglar may determine the correct combination given enough time.

combination locks are vulnerable to shimming in addition to rudimentary trial-and-error cracking. Shimming, not to be confused with picking or bumping, is the process of opening a lock with a special tool called a shim. The shim's purpose is to retract the spring that secures the shackle to the lock's body.

3. Combination locks VS. Keyed padlocks

When opposed to combination locks, keyed locks provide a higher level of security because they don't have dials. A thief won't be able to open it unless he or she possesses the key. In addition, keyed locks are more resistant to shimming than combination locks. For these reasons, a high-quality keyed lock is preferable to a combination lock.
