Transponder keys are said to be more secure for cars and are more difficult to copy by thieves. However, a key may need to be reset if it becomes damaged or lost.
You can reprogram key fobs yourself but you must be aware of the correct procedure. You should have these items to ensure the best results:
Keys
The majority of modern vehicles require a transponder keys to operate. This gives security and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to work with your car's systems and specific model. They are expensive to replace if lost, so you should have spares in your car. You can also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. How can you ensure that the key you purchased is authentic? Can you tell whether it was programmed to work with another vehicle or if it could be programmed to work with your car?
If you're looking to program a new key, the first step is to make sure that your car is operating. Insert the key you'd like to program into the ignition, but don't turn it. There are only a couple of seconds before the car's system reverts the commands and leaves programming mode. This is why it is essential to be quick and not be able to wait between steps. To prevent this from happening, shut off the engine. Change the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful. The door locks will go through a cycle.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to open the vehicle. This feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and later duplicate the signal generated by the key fob of the vehicle to unlock the car. To combat this, manufacturers added security features known as the CAN bus protocols to stop hacking.
Some manufacturers use a special encryption on their keys that cannot be decoded using a simple program. These types of cars will need to be programmed by a professional, so you should only attempt this process if you have experience working with electronic devices. It is a good idea to consult the owner's manual for your car or look up the manufacturer on the internet, since these steps vary by car model.
Transponder chips
Car keys with transponder chips require a special reconfiguration to work. While any hardware store can cut keys for you, the main challenge is making it function with your specific car. The key has to be programmed to match the exact identification code on your car, or else it won't be able to start.
Transponder chips are a standard feature in modern cars and are designed to prevent car theft. The chip is a microcircuit that transmits 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 original one that was programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it harder for thieves who aren't experienced to wire a vehicle hot and then start it.
The key and the chip are connected by a circuit board that includes an induction coil. When the key is placed in the ignition the magnetic field is generated 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 identification number is sent back to the car and the engine will start if the identification number matches.
There are many ways to program a key transponder, however all require an instrument that is specifically designed for. You can buy these tools online or at most locksmiths in the automotive industry. They're not cheap, but they are vital for programming the chip to your vehicle.
You may also use a reprogrammable key that was previously programmed for a different vehicle. In this instance you'll need sure that the key isn't damaged or that the transponder has been altered in any way. You can read the chip by using a scanner or a computer equipped with an USB connector.
