Different Types of Lock Part Six

Meanwhile others will use a magnetic swipe card that will be cheaper to mass produced and can be removed from the system should something go wrong. Finally others will use biometric data such as finger prints or voice recognition meaning that the individual will be guaranteed to always have their identification on them and meaning they can quickly and easily access the door without having to fiddle with actually turning the lock. All of these types of keys are suitable for doors which have multiple people coming and going who might otherwise lose keys requiring the locks to be regularly changed. Using any of these systems a digital lock can simply remove someone from the system should their swipe card go missing. Thus they are often found in the external doors to blocks of flats and in large businesses.

A car key uses metal contacts that complete a circuit in order to create a spark to set off the ignition. As such any damage can prevent the circuit from being completed and thus stop the car from starting. Many car locks also make use of a remote that works from a distance and these too can sometimes need repairing which would mean simply replacing small components on a circuit board.

Different Types of Lock Part Three

This is the shape of key that you might draw as a child. One reason that the cylinder lock is used for front doors over the lever lock is simply that the key is larger and thus more impractical to carry around for you. At the same time lever locks, while they use a very similar practice to the cylinder lock (but using a lever instead of a cylinder as the names suggest), also do not have quite the same high amount of variations making them marginally easier to pick and so slightly less secure on an outside door. For these reasons the lever lock is most likely to be found on inside doors to the bathroom/bedroom etc.

Cylinder lock: A cylinder lock is the lock that we often associate with locksmiths and that we will deal with on a most regular basis. This is the lock that goes on the front door and that keeps our home safe and secure from trespassers in the majority of cases. The cylinder lock is made from a mechanism that itself is comprised of a barrel inside a cylindrical chamber. This cylinder then is held in place by a number of small metal ‘pins’ but when the key is inserted, the small ridges on the blade push each pin up and out of the way and this allows the chamber to turn which opens the lock. A cylinder lock can easily be identified by the key which has a round handle and the blade coming straight out of this handle. Chances are that your front door key looks like this.

DND Key

A DND key is a ‘Do Not Duplicate’ key. These keys are designed not to be duplicated but in a passive way by the locksmith who provides them. The passive method used by the locksmith here is simply that the lock says on it ‘Do Not Duplicate’ or ‘DND’. This then instructs other locksmiths and key cutters not to attempt to copy that key, and most locksmiths will respect this.

Surveillance Cameras for Small Business Part Two

By installing surveillance cameras these temptations just won’t exist. There are other benefits to surveillance cameras too, and not all of these even relate to security. For instance cameras allow you to watch you staff and see how they are interacting with each other and customers so that you can analyse how well your business is operating. Furthermore they allow you to keep an eye on your business and to look out for other potential problems. These might include things like fires, or accidents where someone falls down.
