Thanks, but my remote needs no button to be pushed. When I walk up to the car and touch the door handle, all door locks snap open. How does the car know that the remote is in my pocket?
You walk up to a car, touch special area, which makes the car itself to transmit special signal... Your key detects it (it is not constantly transmitting, but it is "listening" to certain signals, which takes less power), transmits the unlock signal to the car, the car opens... If you can emulate your car's transmitter signal - I guess you can make the key to also start transmitting its own signal... But that's probably not as easy as it sounds, especially if, for example, the key's battery is low or is completely dead (the key won't transmit anything without power source... That's why these things usually have a back-up mechanical key).
