Hi,

Today I found my self unable to turn the ignition from run to off. Key is stuck. I know I have VATS but I wasn't sure if VATS could be doing this or is it just a bad tumbler/lock.

I thought a VATS problem would not prevent the key from turning but would disable the engine (eg. no fuel/spark)

True? If so is a VATS ignition much more $ than a regular one? If so what part would I ask for to get a non vats ignition?

Thanks for any help

Correct. I've never seen, read, or heard of VATS mechanically interfering with the key. Sounds like the lock cylinder has malfunctioned.

I don't know the part number but, it's my understanding that the VATS lock cylinder is a lot more expensive because you also have to get a new chipped key.

Hope this helps!

 

VATS lock cylidners interchange- it's only the resistance of the chip in the key that differs.

 

before you tear into the column, make sure the shifter bowl on the column down near dash moves fully to the park position.

if you do need a new lock cylinder, stay away from the aftermarket VATS lock cylinders. they are only a little cheaper than a Delco lock cylinder and they don't last very long.
you can use a plain non-VATS lock cylinder, but you must do the VATS bypass talked about in the technical section here,

I thought so - I will check the park interlock or whatever it is - (I think that's what you were suggesting)

I am running a custom prom I did years ago and I am pretty sure I have VATS disabled.

It seems like going with a standard lock set is simpler since I believe if I get a new VATS lock, I'd need to get a VATS key made that matches the resistance of my current key (not sure how that works but it doesn't sound cheap)

So can I just get an autozone $12 non VATS for my year firebird and expect it to work?

thanks everyone,

if you have already disabled the VATS system including the starter lockout, then there is no need to get a VATS lock cylinder.

i've installed a fair number of the non VATS after market lock cylinders and though sometimes you may need to wiggle the key a little, they seem to work fine.
