Transponder chips

Transponder chip car keys require special reprogramming in order to function. smart key programming can give you an entirely new car key, however the real challenge lies in implementing it to your car. A reprogrammed key will need to be compatible with the specific identification number of your car, or it won't start the engine.
Transponder chips are a standard feature of modern cars and are designed to prevent car theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is placed. The car then detects the signal and begins the engine if it matches the original one that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it more difficult for thieves with no experience to wire a vehicle hot and then start it.
A circuit board that has an induction coil connects the key to the chip. When the key is placed in the ignition, a magnetic field is generated around the transponder. This generates a signal, which is received by the coil and then transmitted to the key's identification number. The key's ID number is sent back to the vehicle, and if it is in line with the engine will start.
