Keys
Most modern vehicles require a transponder key or fob in order to operate, ensuring security and protection against theft. The keys have to be programmed to your specific car and its systems by a licensed dealer or locksmith. They can be costly to replace if they are lost and it is recommended to keep spare keys in the car. You will also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. But how can you tell that the new key fob you bought is genuine? Can you tell if the unit has been programmed to work with another vehicle or if yours can be programmed again?
To program a new car key you must first verify that your vehicle is running. Insert the key you want to reprogramme into your ignition, but don't turn it. There are only just a few seconds before the car's system reverts the commands and then exits programming mode. It is important that you be quick and don't be patient between each step. Turn off the engine to prevent this. You can test the car's system by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you will hear a chime to indicate that the procedure was successful.
Some newer vehicles use rolling keys to keep thieves from using stolen keys to open the car. This feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and then duplicate the signal generated by the key fob of the vehicle to open the car. To prevent this, manufacturers have added an additional security feature known as the CAN bus protocol to thwart hacking attempts.
Certain manufacturers employ a specific encryption on their keys that can't be decoded with a simple program. These types of vehicles require programming by a professional, so you should only try this with someone who has experience with electronics. Refer to the manual for your car or visit the manufacturer's website to learn how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. Any hardware store can give you a new car key but the real challenge lies in making it work with your car. A reprogrammed key will need to match the exact identification number of the vehicle otherwise it won't even start the engine.
Transponder chips are a typical feature in modern cars and are designed to prevent car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car then recognizes the signal and begins the engine if it matches the original one that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it much harder for car thieves with no experience to wire a vehicle and 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, it creates an electric field around the transponder. This creates a signal that gets amplified by the coil which transmits it to the key's identification number. The ID number of the key is transmitted back to the vehicle, and if it matches the engine will begin to run.
There are several ways to program a transponder, however all of them require the use of a specific tool. You can buy these tools online or at most locksmiths in the automotive industry. These tools are not expensive, but they are essential for programming your car's chip.
You can also use an unreprogrammable key that was programmed for an alternative vehicle. In this case, make sure that the key has not been damaged or that the transponder is not altered in any way. To do this, you can use scanners or a computer with an USB port to scan the chip and determine its identity.
Reprogramming the transponder key is simple, but it requires an expertly designed software and scan tool. If you're a beginner you should seek help from an auto locksmith. You should also avoid buying second-hand keys, since they're probably already programmed and will not work with your vehicle.
