You can find key fobs that can be replaced in online stores as well as many brick-and mortar auto shops. But how can you tell that the one you purchased is authentic?

If you're looking to program an entirely new key the first step is to make sure that your car is running. Insert the key you want to program into the ignition without turning it. You only have a few seconds before the car's system reverts the commands and then exits programming mode. This is why it is essential to be quick and not be able to wait between steps. To avoid this happening, shut off the engine. You can check the system of your car by turning the key to the "on" position and back to the "off" position. There should be a chime to indicate that the process was successful. The door locks will go through a cycle.

It allows thieves to record and then reproduce the signal received from the vehicle key fob to unlock the car. To stop this, manufacturers have introduced an additional security feature known as the CAN bus protocol to stop attacks on hacking.

This makes it more difficult for thieves who are not experienced to wire a vehicle and then start it.

A circuit board that has an induction coil connects the chip to the key. When the key is put in the ignition, a magnetic field is created around the transponder. This creates a signal which is received by the coil before being sent to the key's identification number. The key's ID number is transmitted back to the vehicle and if it matches the engine will begin to run.
