Locksmith Trade – The Origines

Locksmith Trade – The Origines.

The word locksmith would somehow conjure images of extremely large key to open an equally large door, is it not? It gives you the impression that behind the heavy door is something extraordinary, a treasure, waiting for you. Well, it is just the impressions anyway but there is certainly much history behind the word and the locksmith trade.

Locksmith Trade – The Beginnings.

The story of the locksmith trade is very closely knitted to that of the blacksmith but they did not exist till the early medieval ages. Before, locksmiths did not exist because there were hardly any locks at that time to be used. During those times, household’s locking mechanisms are also of crude and very rudimentary design which does not really need any sort of special attention.

It does not appear so, but the locksmith trade is a trade with a history that is quite the ancient. The oldest lock to have been known is said to be about 4000 years old of Egyptian origin while there is there is the pin and tumbler type of key that is over 2500 years old. This key is amazingly still used today, albeit it has been designed to a much, much better version.

But just as mentioned in a statement before, the term itself did not surface until years after because locks were not used frequently those days. It is only until recent years that the word ‘locksmith’ came to and that happened when the blacksmith trade had experienced quite a development as well. The blacksmiths are those who forged items out of metals both for domestic and wartime reasons.

Examples of items that blacksmiths create include weapons, metal tools, horseshoes, and then after some advancements, they also created locks and keys.  In essence, the blacksmiths are the first locksmiths where you can get the first locks. It was then that the demand for more keys and locks as the years passed came.

Locksmith Trade – Recognized.

When the need for keys and locks increased, it did not take long enough for the trade of locksmith to be recognized and stand on its own as a profession. From then on, it experienced a steady pace of development that continued to the 21st century. It is not a secret how crimes became a steady problem these days.

Criminals have gone wild and gained more confidence over the years prompting people to take extra measures to protect themselves. This is where locksmith services come in. We all are scared over our safety and the security of our properties and locks are one of the things to help us get peace of mind. On that note, locksmiths all work real hard in order to build unique and reliable locking mechanisms to ensure your safety.

The locksmith trade is considered to be a family business and thanks to that, locksmith technicians were able to pass down the trade despite the halt in its advancement due to World War II where many of them were drafted to the military. Fortunately, after the 1950s innovation and industry were back and so technology and engineering were back as well. By that time, the locksmith trade experienced continued advance in terms of skills and expertise up to these days.

Transponder Car Keys

About The Transponder Car Keys.

Function-Added Security.

When the correct mechanically cut key is turned in the ignition, the engine control unit (ECU) on the car sends an electronic “coded message” to the key, and it will only allow the car to start if “coded message” on the key matches. This additional security is intended to reduce the risk of auto-theft.

How Does A Transponder Car Keys Work?

In basic terms a transponder is a miniaturized electronic chip that has what is called non-volatile memory. Non-volatile memory is the type of memory that does not need constant energy for retention. Along with that electronic chip is a set of windings; very fine wire coiled around a tube. These windings look similar to the windings you would find in an electric motor.

Automobile manufacturers utilize magnetic coupled transponder systems. Magnetic coupled transponder systems are passive in nature. This means they do not require constant electricity and do not need a power source of their own. They operate in the frequency range area of 125 kHz. Since magnetic coupled transponders do not have their own power source they are very limited in range of communication and generally operate in the range of ½” to 6”. Since this is a radio frequency it can penetrate materials that would make the transponder not directly visible, such as the plastic or rubber in the bow of a key or fob.

The process of key identification is similar in most automotive transponder systems. Once a key is inserted into the ignition lock and turned to one of the ‘on’ or ‘run’ positions, the induction coil that is mounted around the ignition lock sends out an electromagnet field of energy. The windings in the transponder chip absorb that energy and power the electronic chip to emit a signal.

The signal is usually a unique alpha-numeric sequence which is considered the identification code. The induction coil reads the signal and sends it to some type of computer device to recognize the signal. If the signal is recognized as being already in the computer’s memory the signal is accepted and other electronic components in the vehicle are set into motion to allow the starting of the vehicle or the continuation of the engine running.

Programming Requires Specialized Equipment & Training.

Remote keyless entry fobs emit a radio frequency with a designated, distinct digital identity code. Inasmuch as “programming” fobs is a proprietary technical process, it is typically performed by the automobile manufacturer but trained and qualified technicians may be found at many locksmith, hardware and even battery supply businesses (In point of fact it is a computer in the car which is programmed in the process, not the fob itself.) In general, the procedure is to put the car computer in ‘programming mode’. This usually entails engaging the power in the car several times while holding a button or lever.

It may also include opening doors, or removing fuses. The procedure varies among the various makes, models, and year of the vehicle. Then, once in ‘programming mode’ one or more of the fob buttons is depressed to send the digital identity code to the car’s onboard computer. The computer saves the code and the car is then taken out of ‘programming mode’ and the vehicle is ready to go.
