How do you ensure that the new one you purchased is authentic? Are you able to tell if it has been programmed for a different vehicle or if it can be programmed to work with your car?

To program a new car key, first make sure that your car is running. Insert the key you wish to program into the ignition without turning it. You have only a few seconds before the system resets all commands and leaves the programming mode. For this reason, it is crucial to move fast and not pause between steps. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should cycle, and you'll hear a chime signalling that the process has been successful.

Transponder chips are a common feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the key is put into the ignition. The car then recognizes the signal and begins the engine in case it matches the original signal that was programmed into the vehicle. The car is also programmed to shut down when it detects an incompatible frequency. This makes it much harder for novice car thieves to hot wire a vehicle and then start it.

A circuit board equipped with an induction coil connects the chip to the key. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal that is taken up by the coil and then transmitted to the key's identification. The key's identification number is transmitted back to the car and the engine is started when the identification number matches.
