Someone punched in my car door locks, damaging the area around the keyhole. I wanted to just replaced the lock and cover it up by getting a keyhole guard/plate to save some money on repairs. But while surfing the web, I came upon mentions of show cars having their keyholes and handles"shaved". Basically it's like the keyhole was never there and you have a real clean look. What I would like to know is about how much does it cost to have done, and how do they actually fill the hole? Thanks for any info.
