When the key was dropped it could have broken a solder joint for the EWS transponder. That EEPROM must be able to communicate with the EWS control module & DME/ECU. And it also needs the charging coil to operate...and that may have been damaged as well. Looks like you need to do some surgery and go back in....or get another key.
