In a safe, there is a piece called the fence resting just above the wheels. The fence falls into this gap under the force of its own weight. With the fence gone, the bolt can slide freely past and the safe can be opened. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close. Mobile Newsletter chat dots.

Home Improvement. Home DIY. Household Safety. In other words, you can open them either by turning the dials to the correct position or by inserting and turning a key. The biggest problem with combination locks is that they can be cracked through trial and error. For example, if a combination lock has three dials, each of which is numbered zero through nine, it will only have a total of different combinations.
While this may sound sufficient to protect against cracking, a motivated thief can probably find the correct combination in less than an hour. Of course, some combination locks have more than three dials. And the more dials it has, the harder it is to crack through trial and error.
Given enough time, though, a thief can guess the right combination, regardless of how many dials the lock has. In addition to rudimentary trial-and-error cracking, combination locks are also susceptible to shimming. Not to be confused with picking or bumping, shimming involves the use of a special tool, known as a shim, to open a lock.
The shim is designed to retract the spring that holds the shackle to the body of the lock. Since they don't contain dials, keyed locks offer a superior level of security when compared to combination locks. Unless a thief has the key, he or she won't be able to open it. The exact operation of a combination lock depends on the amount of numbers it takes to complete the combination. Each number has its own wheel, each of which is operated by the combination dial. Each wheel also features a notch and a tab.
As you correctly enter the numbers using the combination dial, each wheel connects with the one next to it. This will cause the lock to unlatch, and access will be granted. Combination locks may range in effectiveness. Even a standard combination comprised of three numbers may be difficult to crack, but locks with additional numbers offer substantially combinations and may give a potential intruder or thief a much more difficult time.
