You can locate key fobs that can be replaced in online stores, as well as 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 whether it was programmed to work with another vehicle or if it is able to be reprogrammed for yours?

If you're looking to program a new key first, you need to ensure that your vehicle is running. Insert the key you wish to reprogramme into the ignition, but don't turn it. You only have a couple of seconds before the car's system resets the commands and then exits programming mode. This is why it is important to be quick and not wait between steps. Shut off the engine to stop this. You can test the car's system by turning the key to the "on" position and back to the "off" position. You should hear a sound signalling that the procedure was successful. The door locks will be able to cycle.

A reprogrammed key will need to match the specific identification number of your car or else it won't be able to start the engine.

Transponder chips, used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted in the ignition. The car then recognizes the signal and starts the engine in case it matches the original one that was programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it difficult for thieves with no experience to connect a vehicle to a hot wire and then turn it on.

The key and the chip are linked by the circuit board which includes an induction coil. When the key is inserted into the ignition it creates an electric field around the transponder. This produces a signal which gets absorbed by the coil, which transmits it to the key's identification number. The key's ID number is sent back to the vehicle and if it matches the engine will start.

There are many methods to program a transponder key however, they all require an appropriate tool. You can purchase these tools on the internet or at many locksmiths for cars. They're not cheap, but they are essential for programming the chip in your car.

You could also use a reprogrammable transponder key that was previously programmed for another vehicle. In this case, you'll need to make sure that the key has not been damaged or the transponder been altered in any way. You can read the chip using a scanner, or a computer with the USB connector.

The process of reprogramming a transponder key is quite easy, but it will require special software and a scanning tool. If you're a beginner, it's best to seek out the help of an auto locksmith. Also, avoid buying second-hand keys as they're probably already programmed and will not work with your vehicle.
