You can find key fobs that can be replaced in online stores, as well as many brick-and mortar auto shops. How do you ensure that the one you have bought is authentic? Are you able to tell whether the unit has been programmed to work with another vehicle or if it could be programmed again?

You only have just a few seconds before the car's system resets commands and leaves programming mode. It is essential to move quickly and don't wait between each step. To avoid this happening, shut off the engine. Switch the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful.

Certain newer vehicles have rolling key technology that prevents thieves from using a stolen car's key to start it. This feature is still susceptible to a technique known as replay attack.

Transponder chips are a common feature of modern cars and are designed to prevent car theft. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is put in. The car is able to detect the signal and begins the engine only if the signal is in line with the original that was programmed in the vehicle. The car will also shut down if the frequency is invalid. This makes it much harder for car thieves with no experience to wire a vehicle and start it.

A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition it creates a magnetic field created around the transponder. This generates a signal that is amplified by the coil which then transmits it to 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 begin to run.
