If it's an automatic, your issue sounds like it might be a failing BTSI that has gone undiagnosed for some time. The BTSI controls the park interlock on the ignition, and when it's failing it usually ends up causing the ignition to get sticky until it eventually won't turn at all. There is a weak switch in the BTSI (I know, another weak switch ) that eventually fails and can cause all sorts of weird ignition issues.

It makes me wonder if your BTSI has been failing for a bit now and it's been misdiagnosed as failing ignition switches. Might be worth a look.

See the thread below for replacement instructions:
Hi Col_Dude, thanks.It;s an automatic. The BTSI has been replaced twice, This last time 4000 miles ago with the ignition switch repair.

Most times I can diddle the little button under the steering wheel and get the key out. Other times, though it's rare, it will go all the way to off like it's supposed to and release the key.

The no turn ignition switch thing happened once before when the car was new on a trip to Oregon.

It's frustrating because the engine and trans will be good for at least 200,000 miles, and it's fuel economy is great. But this has been going on so long, I,ve been looking at alternatives.
