RE: 2002 Seqouia: Key won't turn to "on" or "start" It turns to "ACC" but that's it. Feels like it's stuck. I've tried both sets of keys. Wheels and steering wheel are not locked. A friend mentioned my tumblers may be worn out.??

It is either the key cylinder tumblers worn out or the housing itself. the housing has a small piece that goes into the back of the key cylinder that will break.......i have seen this problem before and it could be either one......i would take it to the dealer or a shop that you can trust that knows how to remove either one without tearing something else up......hope this will help you let me know if i were any help at all......good luck and if you need any other help let me know..........
