You can find replacement key fobs in online stores, as well as many brick and mortar auto shops. But how can you tell that the one you purchased is authentic? Do you know if the unit has been programmed to work with a different vehicle or if yours can be reprogrammed?

To program a new car key, you must first ensure that your vehicle is operating. Insert the key that you want to reprogramme into the ignition, but don't turn it. There are only a few seconds before the system will reset all commands and then exits the programming mode. It is crucial to be quick and don't wait between each step.
