Keys
Most modern cars require a transponder keys to operate. transponder key programming is a security feature and protection against theft. The keys are programmed by a locksmith or an authorized dealer to work with your car's system and the specific model.

You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. But how can you tell that the new one you purchased is authentic? Are you able to tell whether it was programmed to work with another vehicle or if it could be reprogrammed to fit your vehicle?

You only have just a few seconds before the car's system resets the commands and then exits programming mode. It is important that you be quick and don't wait between each step. Turn off the engine to stop this. You can test the system of your car by turning the key to the "on" position and then back to the "off" position.

A key that has been reprogrammed will need to be compatible with the exact identification number of your car or else it won't be able to start the engine.
Transponder chips are a typical feature in modern cars and are designed to guard against car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is placed into the ignition. The car detects the signal and starts the engine only if it matches the original that was programmed in the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.
A circuit board with an induction coil that connects the key to the chip. When the key is put in the ignition, a magnetic field is created around the transponder. This generates a signal that is taken up by the coil and sent to the key's identification number. The key's ID number is transmitted back to the vehicle and if it is in line with the engine will start.
There are many ways to program a transponder, but all of them require a special tool. You can buy these tools online or at most automotive locksmiths. These tools are not inexpensive, but they are vital for programming the chip in your car.
