Most TV remotes use Infra red pulses to control the TV, a few use radio frequency signals, but to use this function, you would need to know what frequencies are used, and you would need a TV remote which can use this mode. (You might be able to use IR to control a model car, but that would require quite a bit of equipment in the car. Then you would need to decode the signals to control the car. This would require quite a bit of electronics to do this job. It would be much easier and cost a lot less to just use a remote which is designed for remote controls of models.
Good luck and God Bless.
