A combination lock is an extremely common type of locking mechanism in which a series of alphabets, typically numbers, are used in order to open the door. These devices can be operated with one key or may require two or more keys. The combination of keys used to unlock the door depends on the combination of numbers that have been entered into either the lock itself or the combination lock screen. Locksmiths use these particular locks to help them figure out how a desired lock should be opened with the necessary keys. A normal combination lock has either a keypad or a screen that is used to enter a number into a keypad, which then activates the unlocking mechanism.
The first number that is used in combination locks is called the key. The key that opens the door is called the shackle, which may be one or more than one line. The shackle may be straight and flush with the door itself, or it may hang off at various angles, depending on the model of the door. On some models of doors, however, it is possible to remove the shackle entirely, by pulling it back out of the slot in the door, and this is how many of these devices are operated.
Dial locks are a third choice when it comes to combination locks and are often used in combination lockers in banks and other financial institutions. Dial locks are created by pressing a number on a dial in order to lock and unlock the door. Once the combination is known, the locksmith can reset the combination with the appropriate key. However, in order for these locks to be effective, a skilled locksmith must know how to operate both the keys and the levers used to lift the door and unlock it.
One type of combination lock that is quite common is the single-dial combination lock, which requires one key for opening and unlocking. This type is often used in combination with deadbolts, however, in order for this combination to be effective, the user must know how to turn the knob so that both the cylinder and the dial are engaged. Another variation of this lock is the double-dex locking combination lock, which consists of a cylinder having two engaging rings, allowing for a single key to be turned in order to open both the cylinder and the dial. The double-dex lock has a very small chance of being opened by a brute force, but is more difficult to disarm via a manual technique. This type also has a reduced level of burglary potential, as it is difficult for a burglar to get in between the dials and the cylinder to disarm it.
A more common type of combination lock for most locations is the combination lock on the keypad itself. Some locking mechanisms use a combination lock on the keypad itself, rather than on the actual door lock. This combination can either be programmed in by hand or can be preprogrammed through a program. In most cases, the combination used on the keypad is not used on the door itself, but rather on a special code that must be entered into a keypad lock programming device. This allows the user to enter a specific combination into a security device to set off an alarm, or to turn the lock on and off at specified times without actually touching the locking mechanism itself. Because of this property, combination locks on keypads are often used as proximity sensors, where a triggering mechanism will trigger the alarm if it is touched, or as proximity sensors over doors or other restricted areas.
A combination lock on a door knob may also be set to start with a first number, which can be followed by other numbers to unlock the door. One example of this is the "bell" combination lock, which requires that you press a button in order to turn the knob; however, in order for the door to unlock, you must first pull up on the handle with the initial number. It is impossible to enter any code into the combination lock of a door knob, but the resulting combination code may be used as a safety feature on your front door to make it less likely that someone will try to force you open.
