You can also find replacement keys fobs in various online stores and in a variety of brick-and-mortar automotive shops. But how do you know that the new one you purchased is genuine? Do you know whether it was programmed for a different vehicle or if it could be reprogrammed to fit your vehicle?

If you want to program an entirely new key first, you need to make sure that your car is operating. Insert the key you want to reprogram key fob into the ignition, but do not turn it. You have just a few minutes before the system resets all commands and then exits the programming mode. Therefore, it is important to move fast and not wait between steps. To prevent this from happening, shut off the engine. Turn the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful.

The key needs to be programmed to match the exact identification number on your car, otherwise it will not start.

Transponder chips are a common feature in modern cars and are designed to guard against car theft. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is inserted. The car detects the signal, and starts the engine only if it matches the original one that was programmed into the vehicle. The car is also programmed so that it will stop if it detects an invalid frequency. This makes it harder for novice car thefts to wire a vehicle hot and then turn it on.

The key and the chip are linked 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 generates a signal, which is received by the coil and sent to the key identification number. The key's ID number is transmitted back to the vehicle and if it matches the engine will start.

The process of reprogramming the transponder key is easy, but it will require an expertly designed software and scan tool. If you're new to the process it is recommended to seek help from an auto locksmith. Avoid buying used keys because they may already be programmed and won't work with your vehicle.
