A 6,000 year old locking mechanism from ancient Mesopotamia is on record as one of the first complicated locks created by men. Ancient Egypt birthed a similar technology – a wooden basic pin tumbler lock.
This goes to show that man has been keen on his security for a very long time, and fortunately has not been dormant in his attempt to create better, stronger, safer locks.
Present day locks exist in a broad variety, coming in varied shapes, sizes and with diverse features. Each design of currently available lock has its unique advantage and disadvantage, and Worthing Locksmith is more than happy to recommend what lock will better suit your needs.
These are mostly installed on doors leading outside. Deadbolts can usually be found in three varieties: Double or Single, or Lockable Thumbturns.
Single cylinder deadbolts are more commonly found on American homes. They can be opened on the outside via a key, but on the inside, they can be opened by utilizing the Thumbturn. Double cylinder deadbolts on the other hand need a key on both outside and inside to open them.
The Lockable Thumbturn merges features of both single and double deadbolts as seen in how it has a Thumbturn on the door’s inside, but unlike the single cylinder, this hybrid’s version can also be locked with a key.
This kind of lock is detachable from what it’s securing, instead of being permanently attached like other locks.
Portable, separate, and easily recognised, padlocks come in various sizes and are made of certain materials depending on the manufacturer and specialized function of the lock. There are two main types of padlocks, combination and keyed.
Combination locks use dials to lock and unlock, but this is dependent on the right combination sequence being entered via the dials.
Keyed padlocks can have either Rekeyable or Non–Rekeyable locks. It’s impossible to use another key to unlock a non-rekeyable.
Then there are key-retaining and non-key-retaining padlocks. A key-retaining padlock’s key can’t be removed while the padlock is open.
Are usually used for the inner doors of commercial buildings. Compared to knobs, they are more user friendly because of their convenient pushdown door handles. If a building takes into consideration handicap accessibility, it will most likely use lever locks rather than knobs.
These are usually installed on external doors of residential buildings alongside deadbolts as a primary source of security.
Rim Cylinder/Mortise Cylinder Locks
These are also commonly found on commercial doors, including glass entry doors and are thought to be more secure in comparison to deadbolts.
Rim locks share a lot of similarities with Mortise locks, but their actual hardware is vastly different. The Rim cylinder’s tailpiece extends out its backside and goes through the door into the locking mechanism on the opposite side when installed. While Mortise cylinders are installed on the side of a door and screwed into the mortise’s hardware already placed within the door.
Jimmy Proof Deadbolts
These surface mount deadbolts (screwed into the inside of the door instead of needing a drill pattern like a standard deadbolt) are mostly found on apartment doors or double doors. Most prefer them because only minimal modifications are required on a door before Jimmy Proof deadbolts can be installed. These locks are unique because the deadbolt once engaged slides into the jamb bracket and prevents it from being forcefully opened from the outside. The Jimmy proof needs only a single slot drilled through the door for its rim cylinder, which means in the event of upgrading a Jimmy proof, all you need to change is the rim cylinder and not the entire mechanism.
Wall Mounted Locks
These locks are actually mounted in the wall. The most popular variety of it is the fireman’s box style lock which can be seen in most commercial buildings as an emergency storage for the keys to a building. Asides from key storage, wall mounted locks can be used as item deposits or small safes. Their installation is usually done during the initial construction of a building but some of these kind of locks can be installed without problem into an already completed and functioning building – The wall surface will determine the amount of difficulty involved in installing a mounted wall lock.
This technology was being applied in cars and hotels way before they were applied for home and office building use. A variety of digital locks exist but they generally make use of pin codes or swipe cards, or a combination of both to unlock them.
Interchangeable Core Cylinder
These are usually used in large commercial buildings and are popular because of their feature of having their locks easily re-keyed by swapping out its core without the need of first taking the entire lock apart.
Interchangeable Core Locks have two kinds of keys that work with them; Standard operator keys which lock and unlocks it like a normal lock, and the Control key which pulls out the entire core of the lock when used, without having to first take out any screws.
The control key feature is most useful when changing or upgrading locks because the hardware and the rest of the door is left undisturbed, and because it takes very little time to swap out locks.
Rim Latch Locks
These aren’t built to withstand a forced entry but can be paired with other locks to reinforce a door. The rim cylinder is standard on one side of the door, and has a mounted surface latch lock on the opposite side. They have an auto lock feature once the door closes and are quite popular in apartment building.
This form of locking technology is still fairly recent and hasn’t gone fully mainstream. This advancement in technology was born out of the perceived increase in the use and applications of smartphones. These locks can be operated remotely by simply using an app on a smartphone to control the locking and unlocking of a door.
If you so wish, a combination of a smart lock and a traditional lock can be used to secure your home or business.
