Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. However, keys may require reprogramming in the event that it is damaged or lost.

You can change the key fobs you own but you must be aware of the correct procedure. It is essential to have these items to ensure the best results:

Keys

Most modern vehicles require a transponder key or fob to operate, ensuring security and anti-theft protection. The keys must be programmed to your particular vehicle and its features by a licensed dealer or locksmith. They can be costly to replace in the event of loss therefore, you should have spares in your car. You can purchase key programming car fobs that can be replaced in online stores, as well as many brick-and mortar auto shops. But how do you know that the one you purchased is genuine? Do you know if the unit has been programmed to work with a different vehicle or if it could be programmed differently?

If you're looking to program an entirely new key, the first step is to ensure that your car is operating. Insert the key you want to program into the ignition, but do not turn it. You have just a few minutes before the system resets all commands and exits the programming car keys mode. It is important that you move quickly and don't delay between each step. Shut off the engine to stop this. Turn the key from “on” to “off” to test the system. The door locks should be able to cycle, and you'll hear a chime signalling that the process was successful.

Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the car. This technology is still vulnerable to a method known as a replay attack that allows thieves to record the signal received from the key fob of the car cut and program car keys then replicate it to open the car. To counter this, manufacturers have added an additional security feature known as the CAN bus protocol to stop attacks on hacking.

Certain manufacturers also have special encryption on their key fobs that cannot be decoded with a simple program. You should only attempt this method if your previous experience is with electronics. Consult your car's manual or go to the manufacturer's website for information on how to program it. The steps to follow will differ depending on the model of vehicle.

Transponder chips

Car keys that feature transponder chips need special programming to function. Any hardware store can give you a new car key, however the real challenge lies in implementing it to your vehicle. The key has to be programmed to match the exact identification code on your vehicle, or else it will not start.

Transponder chips are a typical feature of modern cars and are designed to guard against car theft. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car detects the signal and begins the engine only if the signal matches the original that was programmed in the vehicle. The car is also programmed so that it will shut down when it detects an incompatible frequency. This makes it harder for thieves with no experience to connect a vehicle to a hot wire and then start it.

A circuit board with an induction coil that connects the key to the chip. When the key is placed in the ignition, it creates a magnetic field around the transponder. This generates a signal that is received by the coil and sent to the key's identification number. The key's identification number is then sent back to the car, and the engine starts if the identification number matches.

There are many methods to program a key transponder, however all of them require an instrument that is specifically designed for. These tools are available on the internet or at most auto locksmiths. These tools aren't cheap but are essential for programming the chip in your car.

You could also use a resettable key that was programmed for a different vehicle. In this scenario you'll need sure that the key isn't damaged or the transponder has been altered in any way. To do this, you'll need a scanner or a computer equipped with a USB port to scan the chip and determine its identity.

Reprogramming a transponder key is quite easy, but it will require specialized software and a scan tool. It is recommended to contact an auto locksmith for help in case you're not an expert. You should also avoid buying second-hand keys, since they're likely to be programmed and won't work with your vehicle.
