I highly doubt the transponder pill fell out of the key or the car wouldn't start, even if it is still in the car. The pill must be right next to the ignition for the signal to be received by the transponder behind the dash. You are probably confusing the circuit board for the remote buttons with the transponder pill. They are two separate parts. Look down by the key blade in the inside of the key housing and you will see a small black pill. That is the transponder 'chip'.
