2001 Pontiac Sunfire Key wont turn

My key wont turn the ignition, it yakes a whole lotta jiggling and adds ALOT of stress on me. Thinking I should get a new key cause mine looks worn, but dont wanna spend the money of I get new key and find out I need whole new cylinder lock. Ive sprayed electrical component cleaner inside, and tap on it with little hammer, and the key is straight, so what should I do. And I heard there was a recall for the ignition
