Replacing ignition key?

Hey y'all, the key to my 30 was thrown away on accident, no foul play, and I was wondering if a locksmith could make a new key that would work or if i would have to go about changing the locks and ignition cylinder or what ever that whole process would be. I have a way to get the car unlocked but the ignition surprisingly isn't able to be turned by trying any picking or unsurprisingly i'm bad at picking the lock. Would appreciate any info!
