Transponder chips Transponder chip car keys require a specific reprogramming to work. Any hardware store can give you a new car key but the real challenge lies in integrating it with your car. The key must be programmed to match the exact identification number of your car, otherwise it will not start. Transponder chips are a common feature of modern cars and are designed to stop 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 matches the original frequency that was programmed into the vehicle. The vehicle is also programmed to stop if it detects an invalid frequency. This makes it more difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on. A circuit board that has an induction coil connects the key to the chip. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates 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 is started if the identification number matches. There are several ways to program a transponder, but all require the use of a specific tool. You can buy these tools online or from most locksmiths for cars. These tools aren't cheap but are essential for programming the chip in your car. You may also use a resettable key that was programmed for another vehicle.
