Already been through this Indy....U may try squirting wd-40 in it . A couple of yrs ago the dealership got me for $1,500 , had to have it towed . A good local repair shop may B able to help you , but U may or may not B able to keep your old keys. They say the problem is in the "plastic tumblers" vs. metal ones . We have a large group on the site w/same prob. Look us up . We tried for a recall but heard nothing...Ron in Louisville.
