These cars have a shift interlock switch that prevents the car from being shifted out of park if you don't depress the brake. If your brake lights work, then the switch it good. It isn't uncommon that the interlock solenoid fails. The solenoid moves the lock release when you depress the brake. If you look on the side of the console you can see a notch cut out. You can put a screwdriver in there to push the interlock and shift it from park. Of course, you don't want to do this all the time so you either need to replace the interlock solenoid (last I checked they were about $150) or just defeat the solenoid with a zip tie. The only problem with the zip tie is that you don't have to depress the brake to shift it from park and it can be shifted from park even if the key is not in it. Your owners manual will have better detail and pictures of the interlock and where to put the screwdriver to manually shift it from park.

I got mine fixed. Had to change the cable and the whole shifter assembly. It wasnt too bad in price, less then $200 total, and my son-in-law changed it in about 1/2 hr in the driveway. Just go to the dealer and get the parts break down for that area and get the cable and chances are, you will need the assembly too.

Look at the swith on the brake pedal, it shoud have two green wires on it. Make sure it is not melted or the wire is broken. If it is damaged you can connect the 2 wires together to get it into gear, but this should be temporary as it bypasses the neutral safety switch.
