I found out that there is a plug under the steering wheel where you can insert an item and release the locking mechanism. A real pain in the neck.

Update from Mar 21, 2011: I pulled the console and sprayed WD-40 where the park lock button mechanism is visible and pushed the button alot of times and finally the joker works.

My key gets stuck in the ignition - often - I have to use my spare key to lock the car with the key in the ignition - I drape something over the steering column in hopes that no one would know the key is hanging there. I'm trying to find out if this is a recall problem.
