I have a 2001 and the ignition is acting a little weird. It starts and shuts off OK but I can pull the key out when it running and sometimes have problems getting the ignition switch to the right position when shutting it off (the cars acts like the key is still in - alarms go off when door is opened, etc.)

I bought this car used and the keys were really worn down - had trouble getting doors unlocked. I got a key code from a dealer and had a non-chipped key made to open the doors and trunk and that seemed to work there.

Could it be the keys are worn or is the ignition wearing out as well? I am thinking about getting a new chipped-key made.

Any help would be appreciated
