I’m not sure if this is the right forum to ask but does anybody know if it’s at all possible to commercially acquire a much smaller version of a key fob? And if that’s not possible, the means to make a smaller chip that can emit the same radio frequencies? The application of this question come from my desire to put a key fob inside of a hotwheels model of my own car and mine not being small enough. (Pictures used to demonstrate desired size of Radio transmitter: something about <=3/4” W x <=5/8” L and with a depth of <= 1/4” would be perfect)
