How do you replace the door locks without completely f'ing up the door panel? I finally managed to break my key off in the one that actually worked fine so I ended up spending like 10 - 15 minutes fiddling with the other one that wasn't working too well to get in my car last night.

I'd imagine I just need a couple of new cylinders and obviously keys to go with them. Those can't be too bad of a price... can they?

 

I have corvette america's parts catalog and they are listed as follows:
#23813 $27.99 pair.
