Transponder chips
Car keys that feature transponder chips require special reconfiguration to work. Any hardware store can offer you a new car key, but the real challenge is in making it work with your car. The key must be programmed to match the exact identification number on your car, otherwise it won't be able to start.
Transponder chips, used to prevent car theft, are a common feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signals when the key is put into the ignition. The car then scans for the signal and starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it much more difficult for novice car thieves to connect a vehicle with hot wires and then start it.
The key and the chip are connected by the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal, which is absorbed by the coil and sent to the key's identification. The key's identification number is then returned to the car and the engine will start if the identification number matches.
There are several methods to program a key transponder, however all of them require the use of a specific tool. These tools are available on the internet or at most auto locksmiths. These tools are not cheap but are essential for programming your car's chip.
You can also utilize a transponder that is reprogrammable that was previously programmed for a different vehicle. In this instance, you must ensure that the key isn't damaged or the transponder has not been altered in any way. To do this, you'll need scanners or computers equipped with an USB port to identify the chip and establish its identity.
Reprogramming the transponder is a straightforward procedure, but it requires specific software. It also requires an scanner tool. If you're just beginning, it's best to seek out the help of an auto locksmith. Avoid buying used keys as they may already be programmed, and they won't be compatible with your vehicle.
