These keys are programmed by a locksmith or authorized dealer to work with your car's system and the specific model. It is expensive to replace them if they are lost, so it's best to have spares available. You can also find replacement key fobs at various online stores and in many brick-and mortar auto shops. But how do you know that the new one you have bought is authentic? Are you able to tell if the unit has been programmed to work with another vehicle, or if it can be programmed differently? If you want to program a new key first, you need to make sure that your car is on and running. Insert the key you want to reprogram into the ignition without turning it. There are only just a few seconds before the car's system resets the commands and exits programming mode. Therefore, it is essential to move quickly and not pause between steps.

Certain manufacturers also employ special encryption on their key fobs which are not decoded by a simple program.

Transponder chips Car keys with transponder chips require a specific reprogramming to work. While any hardware store can cut a new key for you, the biggest challenge is making it function to work with the specific car you own. The key has to be programmed to match the exact identification code on your car, or else it won't start. Transponder chips, used to stop theft of cars are a standard feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car detects the signal, and starts the engine only if it matches the original that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it more difficult for thieves who aren't experienced to hot-wire a vehicle and then turn it on. The key and the chip are connected by a circuit board that includes an induction coil. When the key is put in the ignition the magnetic field is generated around the transponder. This creates a signal which is absorbed by the coil and then transmitted 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 several ways to program a transponder key however, they all require a special tool. You can purchase these tools online or from most locksmiths in the automotive industry. These tools aren't inexpensive, but they are vital for programming the chip in your car.

Reprogramming the transponder is a straightforward procedure, but it requires special software. It also requires an scanner tool. If you're new to the process you should seek the assistance of an auto locksmith. Don't buy used keys since they may already be programmed, and they won't work with your car.
