2002 LEXUS ES Unknown Or Other Problems

THE PLASTIC KEY TO MY 2002 LEXUS ES300 CRACKED DUE TO FAULTY PRODUCT DESIGN AND THE MICROCHIP THAT CONTROLS THE CAR FELL OUT. I DID NOT KNOW THIS HAD HAPPENED AND WAS UNABLE TO START THE CAR. I WAS STRANDED IN A RAIN STORM AND HAD TO CALL LEXUS FOR HELP. SUBSEQUENTLY I USED AN EMERGENCY KEY WHICH WAS IN MY PURSE. EVEN THOUGH THE BREAK OCCURRED BECAUSE OF FAULTY DESIGN, I HAD TO ORDER AND PAY FOR A NEW KEY ($206) BECAUSE MY CAR WAS BEYOND WARRANTY. I WAS TOLD BY THE LEXUS SERVICE DEPARTMENT THAT THESE KEYS BREAK "MORE OFTEN THAN WE WOULD LIKE ".CLEARLY, THE DESIGN OF THE KEY IS THE PROBLEM. WHEN THE CAR KEY BREAKS THE CAR IS INOPERABLE UNLESS YOU HAVE ANOTHER KEY WITH YOU. THE DEALER HAS TO ORDER A NEW KEY AND CANNOT START YOUR CAR FOR YOU. THIS IS A DANGER...
