Q: Electrical problems with car

Hello. The key issue is probably due to a worn ignition cylinder. Replacing the cylinder should do the trick. These vehicles are also known for having the key completely stuck in the ignition due to a failure in the shift interlock. But, since you say the key comes out I would lean more towards the ignition cylinder. As for the hazard lights staying on, the problem could be a failed flasher, a failed switch or a short in the hazard circuit. The clicking from the turn signals indicates a problem with the canceling cam. I suggest you have a professional, such as one from YourMechanic, inspect the electrical components in your vehicle and replace any damaged parts.
