But how do you know that the one you purchased is genuine? Can you tell whether the unit has been programmed to work with another vehicle or if yours can be programmed again?

To program a new car keys, first make sure that your car is running. Insert the key you wish to reprogramme into the ignition, but don't turn it. There are only a few seconds before the car's system resets the commands and then exits programming mode. For this reason, it is important to move fast and not pause between steps. To avoid this happening, shut off the engine. You can test the car's system by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you'll hear a chime to indicate that the process has been successful.

Transponder chips are a common feature of modern cars and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is inserted in the ignition. The car then scans for the signal and then starts the engine if it is in line with the original one that was programmed into the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it more difficult for thieves with no experience to wire a vehicle hot and then turn it on.

The chip and the key are linked by the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This generates a signal that gets amplified by the coil which sends it to the key's identification number. The programing key's ID number is transmitted back to the vehicle and if it is in line with the engine will begin to run.

To accomplish this, you can use scanners or computers equipped with a USB port to read the chip and determine its identity.

Reprogramming an transponder's key is simple, however it requires special software and a scanning tool. If you're new to the process you should seek out the help of an auto locksmith. It is also recommended to avoid purchasing secondhand keys, as they're probably already programmed and won't work with your car.
