Transponder Key Copy

Transponder Key Copy

Almost all of the automobiles manufactured in the last 15 years come with a digital micro controller called a transponder key. It works as an anti-theft measure for automobiles and has a micro controller inside them. which is used to communicate with the car telling it that it is an original one. If the car recognizes it, then the automobile starts. If it is not recognized, then the vehicle does not start. These have revolutionized the car security industry.

As you know, the transponder key increases the car’s security, but there is a drawback as well. Suppose the original is lost, then there no way of starting your automobile. You will have to call an automotive locksmith who is an expert in car key transponders. Then the locksmith will attach the computer of the car with a remote computer and check the receiver’s frequency and serial number. Then he will make a duplicate one for that car. He will copy the serial number in the trans receiver. The worst part about this process is that not every locksmith provides this service, and if one does, then the service is too expensive.

Duplicate Car Key with Chips

The duplicate car keys with chips are look-alike of the original ones. The only issue which comes with the transponder key replacement is the material. The original one has good quality material, and the one made with the process of transponder key duplication is made with low quality plastic, but both of them almost feel the same way. The second difference is the quality of the trans receiver. The replacement car key with a chip has a micro controller with a coil attached inside the enclosure. The radio wave emitter emits a radio frequency that the receiver of the automobile can catch. If the fob which is being used to open the car or to start it and it is not opening or starting then there is a very high chance that the materials used to make the receiver are very cheap and does not work as intended, it is because the strength of the transponder is not as strong as the original one.

Which makes the process of starting the car frustrating because the car misses some ignition turns just because of the weak signals of the trans receiver. The microcontroller of the trans receiver is just like a normal microcontroller which is used in remote control toys or tv remotes. The issue of weak signals comes because of the circuitry of the micro controller. It does not run on any external power. Instead, it has a coil that turns magnetic flux into electrical energy. This process is a little technical. What happens is that when you insert the key in the vehicle’s ignition hole, the ignition hole has an electromagnet in it, which transmits wireless power to the trans receiver. It works on the same principle on which the wireless chargers of mobile phone works. The trans receiver turns on and starts transmitting signals before the fob turns. When it is turned, the vehicle’s receiver catches the signs, and the automobile starts. The automobile fails to start when the fob has no power, or the signal is too weak to detect.

Transponder Key Programing

The programming of the transponder key is instead a difficult task. It requires costly and delicate equipment. The equipment consists of a tablet with the operating system installed on it, which is needed to connect to the vehicle’s computer. A small wireless connector connects to your automobile’s connector, which is present right below the steering wheel where your knees go. The connector connects to the connector of your automobile and transmits all of the information told by it to the computer.

Connecting the computer

When the connector connects to the car key chip, the locksmith will open his laptop or tablet and access your vehicle’s computer to check the code or the receiving frequency. It is essential to get inside the vehicle’s computer.

Car Make and Model

What many manufacturers do is that they have a pattern in which they use the frequencies. Like if the locksmith gets the name of the manufacturing company, the model of the it, and the year of manufacturing, he can guess from hundreds of the frequencies that may use the vehicle’s computer to connect with the microcontroller present in the enclosure of the fob. The locksmith does not have much time, so the computer does this job for him.
