Basically, my key won't even go into the driver side door cylinder. I'm going to stop tonight and buy deicer and hope for the best. But the guy who popped my lock said he thinks it's broke and I should take it to a dealership. They obviously want way too much money so I'm trying to find the part for it. Do I need the actuator? Or can you just buy the lock cylinder? Do they come together? Does it come with a key? I'm clueless on this sort of thing haha

It's for a 2003 s60
