My mothers car has been giving us alot of problems with the ignition. In the past 2 weeks it has been a little hard to start the car. The key can be put in the ignition put it wont let you turn. We have just jiggled the steering wheel until it turned. Today it totally locked. I have tried everything I could think of to make it work. It wont move at all. Is it the key and we need to have a new one made? Is it the ignition itself and needs to be replaced? Please help!
