Most modern cars require a transponder key in order to operate. This gives security and protection against theft. The keys have to be programmed to your particular car and its systems by a licensed dealer or locksmith. They are expensive to replace if they are lost, so you should keep extras handy. You can purchase replacement key fobs in online stores, as well as numerous brick-and-mortar auto shops. But how can you tell that the key fob you bought is authentic? Do you know whether the unit has been programmed to work with a different vehicle or if it could be reprogrammed?
If you're looking to program an entirely new key first, you need to make sure that your car is on and running. Insert the key that you'd like to reprogramme car key into your ignition, but don't turn it. You have only a few seconds left before the system resets all commands and then exits the programming mode. It is crucial to be quick and don't delay between each step. To prevent this from happening, shut off the engine. You can test the system of your car by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you will hear a chime to indicate that the process was successful.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the vehicle. This feature is still vulnerable to a technique dubbed replay attack that allows thieves to record the signal received from the vehicle's key fob, then reproduce it to unlock the car. To stop this, manufacturers have introduced a security feature called CAN bus protocol to thwart attacks on hacking.
Certain manufacturers also have special encryption on their key fobs which cannot be decoded by an ordinary program. It is best to only attempt this process if your experience is in electronics. Refer to the manual for your car or visit the website of the manufacturer for information on how to program it. The steps to follow will differ depending on the model of vehicle.
