WHAT CAN I DO IF I LOST THE ONLY KEY I HAD FOR MY LEXUS? I CALLED EVERY LOCK SMITH IN THE CITY AND THEY SAY I HAVE TO CALL LEXUS. I CALLED A LEXUS DEALERSHIP AND THEY SAY THE ONLY WAY TO GET A NEW KEY TO WORK IS TO INSTALL A NEW COMPUTER. 4-5 DAYS AND ABOUT $2,000. HAS ANYBODY AVER BEEN THROUGH THIS? ANY ADVISE YOU CAN GIVE WOULD REALLY HELP ME OUT. THANKS GUYS
