Reprogramming Car Keys
Transponder keys for car keys are thought to keep vehicles more secure and harder for thieves to duplicate. The key could need to be reprogrammed in case of damage or lost.
You can reprogram your key fobs at home, but you need to know the right process. For the best results you must have the following items:
Keys
Most modern vehicles require a transponder key or fob to operate, ensuring security and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to work with the car's systems and the specific model. They are expensive to replace if lost therefore, you should have spares in your car. You can also find replacement keys fobs in various online stores and in many brick-and-mortar auto shops. But how can you tell that the key fob you bought is genuine? Do you know whether it was programmed for another car or if it is able to be reprogrammed for yours?
If you are planning to program an entirely new key the first step is to make sure that your car is running. Insert the key that you want to reprogramme into the ignition, but don't turn it. There are just a few minutes before the system resets all commands and then exits the programming mode. For this reason, it is important to be quick and not be able to wait between steps. Stop the engine to prevent this. Switch 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 procedure was successful.
Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the vehicle. The feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and then duplicate the signal generated by the car key fob to open the car. To prevent this, manufacturers have added an additional security feature known as the CAN bus protocol to stop hacking attempts.
Some manufacturers also use special encryption on their key fobs, which are not decoded by an ordinary program. You should only attempt this method if you have experience is with electronic devices. Refer to the manual for your car or look up the website of the manufacturer for information on how to program it. The steps are different depending on the model of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut a new key for you, the real issue is how to integrate it in conjunction with your particular car. The key you reprogrammed needs to be compatible with the specific identification number of your vehicle, or it won't start the engine.
Transponder chips are a standard feature in modern cars and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted into the ignition. The car then recognizes the signal and starts the engine in case it matches the original one that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it harder for thieves with no experience to wire a vehicle hot and then start it.
A circuit board equipped with an induction coil connects the key to the chip. When the key is put in the ignition, a magnetic field is created around the transponder. This creates a signal that is amplified by the coil which sends it to the key's identification number. The key's identification number is returned to the car and the engine will start when the identification number is in line with.
There are many ways to program a transponder key, however, they all require an instrument that is specifically designed for the purpose. These tools are available online or from most automotive locksmiths. They're not cheap, but they're vital for programming the chip into your vehicle.
You may also use a unreprogrammable key that was programmed for another vehicle. In this instance, you must make sure the key hasn't been damaged or the transponder isn't altered in any way. You can read the chip with a scanner, or a computer that has a USB connector.
Reprogramming a transponder is a simple process, but requires specific software. It also requires the use of a scanner. If you're just beginning you should seek out the help of an auto locksmith. automotive key programming should also avoid buying secondhand keys, as they're likely to be programmed and will not work with your vehicle.
