Locks have existed for centuries. The only difference between the first locks ever created and the current ones is the level of technology. Either way, functionality is one and the same; to keep the entry secure from unauthorised access. This article will explore different types of locks that you can easily order from a locksmith should you require them. The most common are deadbolts, padlocks, levers and knob locks.
Here some suggestions from www.lockmanbirmingham.co.uk for you to try out.
These are designed to work on doors mainly operated from outside. There are three types of deadbolts: The single cylinder deadbolts, the double and the lockable. The single cylinder type consists of a key cylinder on the front facing side and a thumb turn on the inner side to unlock or lock the door. However, this deadbolt isn't break-proof. It has a major weakness. Supposing burglars entered through the window or an opening in your home, they would only need to rotate the thumb turn, and your door would open. The double cylinder deadbolt was created to resolve the single cylinder weakness. In addition to the outer key cylinder, it has another on the inside. Which means you need a key to operate it notwithstanding the side of the door you are standing. The third lockable deadbolt is an amalgam of the first two. It has double key cylinders on the inner and outer face of the lock and a thumb turn that uses a key. Therefore, it is flexible since the thumb turn can also be locked. Even if burglars entered your house, they wouldn't unlock the door from the inside.
If you are after a lock whose attachment is independent of the door, then you should consider a padlock. Apart from their portable nature, they are available in many sizes. There are two types: keyed and combination locks. Keyed locks can either be re-keyable or not re-keyable. The former allows you to use one key to operate several other similar padlocks while the latter allows only one particular key to open it. Combination locks are those that have number dials in place of keyholes. You must have the correct number combinations to open these padlocks. A good lock will have enshrouded shackles at the point where the shoulders raise. It makes it harder to cut it.
- Lever Locks
These locks are commonly used for doors requiring minimal closure, like those of an office setting, where movement in and out through the door is high. They are excellent for the physically challenged people since their handles are large enough for ease of turning. Lever locks can either be left or right-sided thus you should be cautious when purchasing one. One of their significant weakness is, when intense pressure is applied to them, they transfer it to the locking mechanism which damages it.
- Knob Locks
These locks are the most common for exterior doors. Most people combine them with deadbolts for more security. They have one primary weakness which is; the lock cylinder is right on the knob itself. So, simply hammering the handhold off disables the door security. Combining them with other types of locks is hence paramount.
