I changed my ignition switch on a 99 amigo had no key so i used a drill to get it out. did not drill all the way through . i replaced the ignition switch turn the key and it wont start . the key moves freely back and forth in the ignition . what did i damage ? how to fix it and how much is it going to cost me if i fix it myself ? is it something i can do at home ? what type of tool will i be needing ?
