Transponder chips Car keys that feature transponder chips need special reprogramming to work. While any hardware store can cut a new key for you, the biggest problem is to make it work to work with the specific car you own. The key you reprogrammed needs to match the exact identification number of your car, or it won't start the engine. Transponder chips are a standard feature of modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is inserted in the ignition. 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 car will also shut down if the frequency is not valid. This makes it much harder for thieves who are not experienced to wire a vehicle and start it. The chip and the key are connected by the circuit board which includes an induction coil. When the key is put in the ignition, a magnetic field is created around the transponder. This creates a signal which is absorbed by the coil before being sent to the key identification number. The key's identification code is sent back to the car, and the engine starts if the identification number matches. There are several ways to program a transponder, however all require a special tool. You can purchase these tools online or from most locksmiths in the automotive industry. These tools aren't cheap but are essential for programming your car's chip. You could also use a unreprogrammable key that was programmed for another vehicle. In this instance, you'll need to make sure that the key has not been damaged or the transponder been altered in any way. To check this, you'll need scanners or computers equipped with an USB port to identify the chip and establish its identity. Reprogramming the transponder is a straightforward procedure, but it requires specific software. It also requires a scanner tool. If you're just beginning, it's best to seek help from an auto locksmith. Avoid buying used keys because they might already be programmed and will not be compatible with your vehicle.
