Reprogramming Car Keys
Car keys with transponders are believed to make cars more secure and are more difficult for thieves to duplicate. A key may have to be reprogrammed in event of damage or lost.
You can reprogram your key fobs at home, but you should know the right process. For the best results, you'll need the following items:
Keys
Most modern vehicles require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to work with your car's system and the specific model. It is expensive to replace them if they're lost, so it's best to have spares in your possession. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you be sure that the one you purchased is authentic? Are you able to tell if the unit has been programmed to work with a different vehicle, or if it can be programmed again?
To program a new car keys, you must first ensure that your car is running. Insert the key that you want to reprogramme into your ignition, but don't turn it. There are only a few seconds left before the system will reset all commands and leaves the programming mode. It is crucial to move quickly and do not wait between each step. To prevent this from happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should be able to cycle, and you will hear a chime signalling that the process was successful.
Certain cars with more modern technology have rolling key system, which prevents thieves from using a stolen car's key to open it. This feature is still susceptible to a technique called replay attack. It allows thieves to record and later duplicate the signal generated by the vehicle key fob to unlock the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to thwart attacks on hacking.
Some manufacturers use a special encryption on their keys that cannot be decoded by a simple program. You should only try this method if your previous experiences are with electronic devices. Consult your car's manual or look up the website of the manufacturer to learn how to program it. The steps are different depending on the type of vehicle.
Transponder chips
Car keys with transponder chips need special reprogramming to work. Any hardware store can offer you a new car key but the real challenge lies in integrating it with your car. A reprogrammed key will need to be compatible with the specific identification number of the vehicle or else it won't be able to start the engine.
Transponder chips, used to protect cars from theft are a standard feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then detects the signal and starts the engine in case it matches the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it much more difficult for novice car thieves to hot wire a vehicle and start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This generates a signal that is amplified by the coil which then transmits it to 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 a few different ways to program a transponder key however, all require an instrument that is specifically designed for the purpose. You can purchase these tools online or from most automotive locksmiths. They are not cheap, but they're crucial for programming the chip in your car.
You can also use an reprogrammable key that was previously programmed for an alternative vehicle. In this instance you'll need sure that the key isn't damaged or the transponder has been altered in any way. The chip can be read with a scanner, or a computer that has an USB connector.
Reprogramming the transponder key is easy, but it will require special software and a scanning tool. If you're just beginning, it's best to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys as they're probably already programmed and will not work with your vehicle.
