Im having a similar problem now. My key goes in and comes out just fine. But its hard to turn it. Sometimes it wont turn. And I gotta jiggle it a little to get it to turn.
i ahd the same problem , look at the key it might be a little bent but not too noticable where u could really see it ,u kinda got a look at it real good thats what was wrong with mine
I am a locksmith and let me tell you, 92+ Toyota anything tends to get hung up alot and the best thing is dry graphite and a little finesse and it will go if not call a locksmith and tell them you have a problem with one of your split wafers, if you know what your talking about about he might give you a better deal.
