ignition problem

That could be a lot of things, like key switch, battery, starter or starter silenoid. First thing to check is the battery. Turn on the headlights, are they bright? Now try to start it do they go dark? If they do battery is low. If it makes a click when you turn the key, the key switch is good, battery could still be low. If the lights stay bright and it clicks you could have a bad connection at the starter or even more likely the starter is bad and needs new brushes or replaced. The silenoid on the starter could also be bad. These are the first things I would check. It could even be the key, they have a chip in them for antitheft.
