Digital Locks
Lock bumping is a lock picking technique for opening a pin tumbler lock. A pin tumbler lock is composed of a series of spring-loaded stacks called pin stacks. Each pin stack is composed of two pins that are stacked on top of each other: the key pin, which touches the key when it is inserted, and the driver pin, which is spring driven.
When the proper key is inserted into the lock, all of the key pins and driver pins align along the "shear line," allowing the cylinder to turn. When the different length key pins are aligned at their tops by the insertion of the correspondingly cut key at their bases, the tops of the key pins and, consequently, the bases of the driver pins, form a straight line, so that the cylinder can be turned, rotating the key pins away from the driver pins. When no key or the wrong key is in the lock, pin misalignment prevents the cylinder from turning.
When bumping a lock, the key is initially inserted into the keyway one notch (pin) short of full insertion. Bumping the key inward forces it deeper into the keyway. The specially designed teeth of the bump key transmit a slight impact force to all of the bottom pins in the lock. The key pins transmit this force to the driver pins; the key pins stay in place. Because the pin movements are highly elastic, the driver pins "jump" from the key pins for a fraction of a second, moving higher than the cylinder (shear line of the tumbler), then are pushed normally back by the spring to sit against the key pins once again.
Even though this separation only lasts a split second, if a light rotational force is continuously applied to the key during the slight impact, the cylinder will turn during the short separation time of the key and driver pins, and the lock can be opened while the driver pins are elevated above the keyway. Lock bumping takes only an instant to open the lock. The lock is not damaged in any way. Certain clicking and vibrating tools designed for bumping can also be used. These allow for rapid repetition of bumping against locks that have advertised "bump proof" features. Only a rare few key-pin locks cannot be bumped.
Digital Locks are locks that provide additional protection using PIN Code. There are two types of Digital Locks. They are:
- Mechanical Digital Locks
- Electronic Digital Locks
Mechanical Digital Locks
The Lockwood Digital DX Locksets provide a mechanical method of keyless entry. For extra security when under forced attack, the inbuilt clutching mechanism allows the outside knob to rotate without operating or damaging the lock. The factory set 5 digit code is easily changed to any 4, 5 or 6 digit code using the code changing kit provided with each lock.
Lockwood Digital DX Locksets are designed to control access into commercial areas, especially when frequent combination changes are needed to maintain security. As the digital lockset utilizes mechanical operation, electrical wiring is not required. Selected locksets combined with digital access pads provide keyless entry.
Electronic Digital Locks
Yale digital door locks provide you with high security at greater convenience than the traditional mechanical products. These devices are secure while simplifying locking and unlocking.
While a digital door lock is typically a door lock that uses a digital code to open the lock, Yale extended the range to include products that uses proximity cards, remote control fobs and fingerprints for identification and entry.
