Instead of using a key to start the car, i would like to use a push button. When I push the button, an MCU will process data from an RF receiver. If the receiver detects the tx fob (key chain) inside the car, then it will let the MCU start the car.

I'm looking for a Tx module that is designed for constant transmission with low power consumption. The range doesn't have to be far.
