92 Cierra...can't turn key off.

[msattler]

I can't turn the key off in my 92 Cierra......it is stuck in the on position with the car running. Rocked the shift lever, worked the tilt up and down, rocked the steering wheel, all to no avail. Cannot remove key or turn it back to the off position. 2.5l FI....had to remove the injector plug to snub the engine and disconnect the battery so it would not discharge. I can reconnect the injector and battery and the key will go forward to start the engine again.
It did this about a week ago, but after some jiggling around, they key turned off and I thought it was a one-time fluke.
The key never gave any signs of sticking or other trouble ever before, so I am wondering if a new key cylinder might fix this or if there is a problem perhaps with the shift interlock?

The key cylinder or linkage to the switch is the problem, the column must come apart to check/repair the problem.

i agree Max but try a little lubercent on the key 1st.it maybe a stuck tumbler
& buy some time.good luck

Thanks guys.....

Turned out to be the least of all possible evils, I guess.
The key cylinder itself was the culprit. A replacement put things right again.
