Car keys with transponder chips need special programming to function. Any hardware store can make you a new car key but the real challenge lies in implementing it to your vehicle. A key that has been reprogrammed will need to be matched with the exact identification number of your vehicle otherwise it won't even start the engine.

Transponder chips are a standard feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is put in the ignition. The car then recognizes the signal and then starts the engine in case it matches the original signal that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incorrect frequency. This makes it difficult for thieves with no experience to hot-wire a vehicle and then turn it on.

The chip and the key are connected via the circuit board which includes an induction coil. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This generates a signal that is absorbed by the coil before being sent to the key's identification. The key's ID number is sent back to the vehicle, and if it is in line with the engine will start.

There are many ways to program a transponder keys, however, they all require an appropriate tool. You can buy these tools online or from most locksmiths for cars. They're not cheap, but they are essential for programming the chip in your vehicle.
