Keys
Almost all modern cars require a transponder key or fob to work, which provides security and anti-theft protection. The keys have to be programmed to the specific vehicle and its systems by an authorized locksmith or dealer. They are costly to replace in the event of loss and you should keep extras handy. You can find replacement key fobs in online stores and many brick and mortar auto shops. But how can you tell that the key fob you bought is authentic? Do you know if the unit has been programmed to work with a different vehicle or if it could be programmed differently?
If you are planning to program an entirely new key, the first step is to ensure that your car is running. Insert the key you wish to reprogram into the ignition, but do not turn it. There are only a few seconds before the system resets all commands and then exits the programming mode. This is why it is essential to move fast and not be able to wait between steps. To prevent this from happening, turn off the engine. Change the key from "on" to "off" to test the system. The door locks should be able to cycle, and you'll hear a chime signalling that the process was successful.
Certain newer vehicles have rolling key technology that stops thieves from using stolen cars' key to start it. This feature is still susceptible to a technique known as replay attack. It allows thieves to record and then reproduce the signal received from the key fob of the vehicle to unlock the car. To prevent this, manufacturers have added a security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers employ a specific encryption on their keys, which cannot be decoded by an easy program. These types of vehicles require programming by a professional, so you should only try this only if you've worked with electronic devices. Consult your car's manual or look up the website of the manufacturer to learn how to program it. The steps to follow will differ depending on the type of vehicle.
Transponder chips
Transponder chip car keys require a special reprogramming to work. Any hardware store can give you an entirely new car key, but the real challenge is in making it work with your car. A reprogrammed key will need to be matched with the exact identification number of your car otherwise it won't even start the engine.
Transponder chips are a typical feature of modern automobiles and are designed to guard against car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car is able to detect the signal, and starts the engine only if the signal matches the original one that was programmed in the vehicle. The car also shuts down if a frequency is not valid. This makes it more difficult for novice car thefts to wire a vehicle hot and then start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition, it creates an electric field around the transponder. This generates a signal that is absorbed 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 is in line with the engine will start.
There are a variety of ways to program a transponder, but all of them require a special tool. You can purchase these tools online or at most locksmiths for cars. They're not cheap, but they're essential for programming the chip to your car.
You may also use a resettable key that was programmed for another vehicle. In this scenario, make sure the key has not been damaged or the transponder isn't altered in any way. To check this, you'll need scanners or a computer with a USB port to scan the chip and determine its identity.
The process of reprogramming an transponder's key is simple, however it requires specialized software and a scan tool. If you're just beginning it is recommended to seek the assistance of an auto locksmith. You should also avoid buying secondhand keys, as they are likely already programmed and will not work with your vehicle.
