Does anyone know how to build a relay device that can catch a low frequency signal and transmit it to another device?
Do you mean these: https://en.wikipedia.org/wiki/Remote_keyless_system
Note they are 315MHz or 433MHz. That's not what I would call low frequency.
its for education and training purposes only a friend of mine done the same thing for a garage door but wanted to test this on he’s own vehicle.It sounds like you want to build a device to steal cars.
