Why is my car starting without a key?

Clean the battery posts and terminals with the post and terminal cleaning tool, so you have a good connection when you’re done.

What to do if your starter is not cranking?

If so the relay is stuck. You might be able to jar it open by rapping on it with a screw drive. Otherwise replace it. If the starter does not try to crank, there is wiring problem from the battery through the ignition switch to the relay.
