Does anyone know how to replace the key cylinder of a 1991 4runner if I can't get the key to turn to acc?
Or 'how to turn my key'?

I tried WD40, jiggling the key and the steering wheel (seriously hard to), even had a wheel jacked up while doing so.
But no result.

 

this happened to my 95, to successfully remove the cylinder the whole steering column has to come out. on mine I pulled the column and drilled out the roll pin to free the cylinder. that is the only way i can think of without getting the kwey to turn

 

Thanks for your reply Blake.
Sounds like a lot of work....
Before I do that maybe I will try to jam in a screwdriver to turn it to acc. first.
I mean, if that doesn't help I could still fix it be removing the column, right?

P.s. is there anywhere were I could find a number so I could get a new key made?

 

I have read several places that the number is on the passenger door lock. You will need to remove the door panel to acces the lock. I have looked at a passenger door lock before and could not find it. I was thinking it may have been engraved into the assembly but it possibly could of been a tag. It might be worth a shot to look. I was unsuccessful at it. If you do go that route, I would be interested in what you find out.

 

We used to drill out the tumbler just enough to remove it in pieces without damaging the housing. Use titanium or better drill bits, vacuum out all the shards.

 

Ah. The original manual speaks of a 'key number plate' on the key ring and suggest you place that number plate 'with your important papers'.
So I guess in your case someone clued that little number-plate on the door next to the lock (which is a smart place for it).

Well, if I find some time I might as well take a look.

 

Yeah drilling it out....somehow that scares me a bit.
What size should I take?

Right now I have given myself these options in this order:

1. Try to find key number
2. Jam in screwdriver and try to turn to acc.
3. Drill out the tumbler
4. Remove whole steering column

 

I had new keys made for the last three toyotas I had by going too toyota with the vin number and having them look up the key code via vin number. Worked great with all three trucks. However if you have a new key barrel it won't fix your issue.
Two of the three trucks of mine had matching keys and everything was great. The other one the key worked for the doors but not the key barrel.

 

Thanks Schnayke, that will be top of the list.
I will ask tomorrow. I would be seriously impressed if they still have that data for this oldtimer (imported from the US to Sweden), but worth the shot.

 

If this has the original locks remove the right door lock cylinder have a lock smith make you the key .By far the easiest

If you really need to remove the lock cylinder without your Key get a helper to help hold the retaining pin as you drill it out because it will spin.

 

They had it for my 83 trailblazer, and that wasn't even a factory vehicle.
Also for my fun runner which is also a non factory vehicle. from 1987
