I can't seem to get the steering unlocked, the key wont turn from the locked position. The old wiggle the steering seems to do nothing. What options do I have? Can you take the key cylinder out without turning the key? I read somewhere that Toyota can make a new key based on the VIN, would that be worth a try?

Mainly out of curiosity...did you get the key to turn?

Yes the guy I bought the car off said it gets jammed in the 'in' position (as in the way you have to push the key in to turn it to the locked position). A can of degreaser (didnt have WD40 handy) did the trick.

I'm still wondering if I can buy a replacement barrel and key that matches the rest of the car though, this key is worn right down you have to see it to believe it

Apart from calling Toyota i can't think of anything else unless you went to a wrecker and tried to get a new barrel with key. Actually i think most barrels are fairly generic for that period might be easy to get one...but im no expert
