Keys
Most modern cars require a transponder key to operate. This gives security and anti-theft protection. These keys must be programmed to your particular vehicle and its features by an authorized dealer or locksmith. It’s costly to replace them if they’re lost, so it’s a good idea to keep extras on hand. You can also find replacement keys fobs at various online stores and in many brick-and-mortar auto shops. But how do you know that the key fob you bought is genuine? Are you able to tell whether the unit is programmed to work with another vehicle or if it could be programmed again?
If you are planning to program a new key the first step is to ensure that your vehicle is operating. Insert the key you want to reprogram into the ignition, but do not turn it. You have only a few seconds before the system resets all commands and then exits the programming mode. It is essential to be quick and don’t wait between each step. Stop the engine to avoid this. Turn the key from “on” to “off” to test the system. You should hear a chime indicating that the process was successful. The door locks will be able to cycle.

The key has to be programmed to match the exact identification number of your car, otherwise it won’t start.
Transponder chips, which are used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit which emits a radio frequency signal when the key is placed in the ignition. The car detects the signal and starts the engine only if it matches the one programmed in the vehicle. The car also shuts down if a frequency is not valid. This makes it much more difficult for car thieves with no experience 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 placed in the ignition it creates a magnetic field around the transponder. This generates a signal, which is taken up by the coil and sent to the key identification number. The key’s identification code is transmitted back to the car and the engine will start if the identification number matches.
