Even though, generally, a key is only the tool by which a lock can be opened, you can find some keys that are specifically designed with improving security in mind. These keys are generally offered to a limited number of trusted individuals simply because, inside the wrong hands, they can enable someone to undermine a building's security system. Even so, some of these extra-security keys are also out there on the market. Master Key This key is significantly prized by burglars. The key is designed to unlock a variety of keys in a specific set, so are usually used by security guards and building superintendents so they can gain access to any room or apartment. However, a master key can only open locks that have master key mechanisms that match. This can mean the lock has two shear points, but often it means the lock has two cylinders. Contrary to well-liked belief, master keys can't be employed to open any lock the user wishes. If you are trying to find a key that will open virtually every single lock around, then you need to have a Skeleton Key. The bad news is that this sort of key had been consigned to the past mainly because of the development of lock design and security features. Its name derived from its skeletal appearance, having a long thin metal shaft and 1 thin notch on its end. It was created to slip past obstructions, or wards, inside the keyway making it possible to open any lock. Control Key The control key is utilized to remove the cylinder core of removable core locks. These exist for high-security factors, with security services for commercial buildings opting to change the cores frequently to guard against key duplication in specific. The key is designed to release the core from its lock cylinder without causing any damage to the lock itself, and to secure the replacement core. It can operate a separate shear line or sometimes may also serve as a master key. Abloy Key An Abloy key is used to operate what is widely considered to be probably the most secure lock in the world, manufactured by the Abloy lock company in Finland. The key is made from one half of a metal cylinder but the cuts in it are made at distinct angles. Utilized in disc tumbler lock mechanisms, when the key rotates the discs, they each move unique distances before the notch is aligned plus the sidebar drops to release the lock. Their high level of security is ensured by the reality that they are nearly impossible to pick. Valet Keys This security key is exclusive to vehicles and are created to give personnel, like valets, limited access to a vehicle. Since a regular key can open any door and commence the engine, handing over you car keys successfully hands the automobile over to a stranger. Most valet keys only enable access via the driver's door as well as the engine to commence. Extra sophisticated valet keys can even restrict the power of the car's engine, taking the thrill out of joyriding.
