3 Little-Known Facts About Locks

Locks represent one of the most common items in everyday life, found on everything from cars, to homes, to file cabinets. Locks play such an important role in the modern world that it can be easy to overlook their long and varied history. Those who look deeper, however, will find a treasure trove of information. This article will introduce you to three little-known facts regarding locks.

1. Ancient Egyptians Invented the First Door Lock

The oldest known door lock was found in the ruins of the Egyptian palace known as Khorsabad, located in the country now known as Iraq. This door lock is estimated to be roughly 4,000 years old. Incredibly, it was constructed entirely out of wood. Even more incredibly, the lock was operated by more or less the same mechanics as today's pin tumbler locks.

These locks utilized a wooden bar located within a hollowed out portion of the door itself. When slid across into a corresponding hole in the door frame, the bar would prevent the door from being opened. A rudimentary wooden key was inserted into a hole on the front of the door to unlock it. This wooden key had teeth just like today's locks.

The teeth of the wooden key would push up on special pins that acted to hold the wooden bar in place. With these pins lifted, the bar could then slide back, and the door opened. This likely took quite a bit of strength since the bars in question were up to 2 feet long and made from solid wood.

2. Romans Flaunted Keys as Signs of Wealth

The Romans tend to be credited with the development of the first metal locks. These followed the same tumbler design as Egyptian wooden locks — although they tended to be somewhat smaller. Locks were used on chests to contain items of great value. To own a key was seen as a sign of great status since it meant that you had objects worthy of protection.

For this reason, many Romans turned their keys into articles of jewelry. They often wore them around the neck on chains of precious metal. Others would have circular portions added to the base of their keys, allowing them to wear them like rings. These keys also often contained decorative elements that reflected the places where the locks were.

3. Modern Lock Mechanisms Stem From 1778

The tumbler locks constructed by the Ancient Egyptians contained multiple pins, each of which had to be lifted upward in order to move the bolt. Yet the distance that you had to lift these pins didn't really matter. They simply had to go high enough to disengage from the slots of a plate at the bottom of the lock.

For hundreds of years — and perhaps thousands — locks continued to operate according to this same basic premise. Yet such locks were flawed in that someone could pick them with relative ease. All a would-be thief had to do was raise all of the internal pins. A new type of lock invented by Robert Barron in 1778 made things much harder.

This new type of lock featured what is known as a double-acting lever tumbler. Inside of the lock were four different levers. These levers differed from those in older locks in that two of them had to be lifted to different heights. This made the task of picking the lot much more difficult.

Locks and keys have a long and colorful history in human societies and have never been more important than they are today. For assistance with all of your lock needs, please don't hesitate to call our security experts at Vista Lock & Safe Co.

Septic systems offer an on-property way to manage household waste, and they can easily rival the performance of a municipal sewer system when properly installed. At the heart of every septic system lies the septic tank. The tank acts as a receptacle for solid waste, while allowing liquid waste to percolate out into the drain field through a special outlet pipe.

Traditionally, most septic systems contained tanks made out of concrete. Today, however, more and more homeowners opt for plastic septic tanks instead. If you would like to learn more about the relative merits of these two options, keep reading. This article takes a closer look at three key advantages of plastic septic tanks.

he first thing you need to do is have new locks installed in all the entry doors. If the doors do not have deadbolts, now is the time to add them. Because you cannot be sure that you possess all of the existing keys, the best thing to do is start fresh on every lock on the property. Working with a locksmith to change all the locks will ensure that the house is secure.

Entry Locks

Entry locks are those locks that secure your front and back doors and any door that leads directly into the home. The locks can be keyed alike for these doors, but keep in mind that means anyone with a key can then open all the entry doors on the house.
But if the locks don't use the same keys, someone with a key will have to try every door to find the one it will open. When someone that does not belong there is poking around, a neighbor may be able to see them and notify the police.  

Sliding Doors

If you have a sliding glass door on your home, the lock that secures it may or may not have a keyed locked on it. If the door does have a lock, getting a locksmith to change the cylinder is a good idea.

Another good idea is installing a door bar in the track that prevents the door from sliding in the frame. Often people use a piece of wood or pipe and lay it in the track, but a door bar is designed to lock into place and is much harder to jar loose than the old broom handle in the track.

An access control system and card security system can provide you with the tools to protect your building on the interior and exterior.

Access control systems effectively lock down a property into different access points that require certain security clearance to gain entrance to. Who you chose to give that clearance to is your choice.

Card reader security systems are installed directly on the major entrances and exit doors throughout the building. In order to gain access, the employee must have a valid card to scan or swipe through the reader. Also, visitors who wish to enter the building will need to be buzzed through the doors by an employee of the building.
