Clean key wont start?
 

my keys will start it??? I drove it to work, then after work I tried starting it and it doesn't click or turn over or anything...all the dash says is, "PLEASE CLEAN KEY AND TRY AFTER 3 MINUTES." I have a chip in my key, but it's not the key. I tried my spare keys too and they don't work either. I checked the fuse for the ignition and it was fine. What would be the best thing for me to do. Please give any information or a link to previous thread as I have not been able to find any information and dealerships just dont have a solution for me. someone has to have had this problem before!
Thanks
