Door Locks-2003 Chevy Avalanche

My door lock on my 2003 Chevy Avalanche was punched in several months ago by a would-be break-in. The lock acutally fell into the door panel leaving just the hole below the door handle on the passenger side. The driver side lock was also damaged. Not punched in, but was loose when I used the key.

I went to the dealer and they said they had to replace the entire door handle assembly for $600. Parts are on back order.

$600 for resetting the locks on my doors! Sounds a bit excessive.

any advice would be greatly appreciated.
