The keys are programmed by a locksmith or authorized dealer to work with your car's system and the specific model. They are costly to replace if lost and it is recommended to keep spare keys in the car. You can also find replacement keys fobs at various online stores and in many brick-and-mortar auto shops. How can you be sure that the one you purchased is genuine? Are you able to tell whether the unit has been programmed to work with another vehicle, or if it can be reprogrammed? To program a new car keys, you must first verify that your car is running. Insert the key that you wish to reprogramme into your ignition, but don't turn it. You have only a few seconds before the system resets all commands and exits the programming mode. It is crucial to be quick and don't delay between each step. To avoid this happening, shut off the engine. 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 to indicate that the process has been successful. Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the car. This technology is still vulnerable to a technique dubbed replay attack, which allows thieves to record the signal from the key fob of the car, then reproduce it to open the car. To counter this, manufacturers have added a security feature called the 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. These types of vehicles require programming by a professional, so you should only attempt this procedure only if you've worked with electronic devices. Refer to the manual for your car or look up the website of the manufacturer to learn how to program it. The steps are different according to the type of vehicle. Transponder chips Transponder chip car keys require a special reprogramming to work. Any hardware store can give you a new car key but the real challenge lies in implementing it to your vehicle. The key must be programmed to match the exact identification number of your vehicle, or else it won't start. Transponder chips, used to protect cars from theft are a standard feature of modern cars. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then detects the signal and starts the engine if it is in line with the original signal that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then turn it on. The chip and the key are linked by an electronic circuit board that contains an induction coil. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that is taken up by the coil before being sent to the key's identification number. The ID number of the key is then sent back to the vehicle and if it matches, the engine will begin to run. There are a few different ways to program a transponder key however, they all require a special tool. These tools can be purchased online or from most automotive locksmiths. They are not cheap, but they're vital for programming the chip to your vehicle. You can also use an unreprogrammable key that was programmed for an alternative vehicle. In this scenario, make sure the key isn't damaged or the transponder isn't altered in any way. To check this, you'll need a scanner or a computer equipped with a USB port to identify the chip and establish its identity. The process of reprogramming a transponder key is quite easy, but it will require specialized software and a scan tool. If you're new to the process, it's best to seek out the help of an auto locksmith.
