Big Problem

symple84

So it all started yesterday when I left my car to get my audio install done at a shop. After running the cables and positioning all the equipment, the car would start. First thing that came to mind was that the steering wheel lock failed so I had it towed to the dealer. First thing this morning, I go to the dealer and they replace the steering wheel lock mechanism and the car still wont start. After tracing all the cables from the audio install, the main power cable was run through the firewall and apparently got cut while being pushed through the sharp hole. Long story short, metal contact on the exposed wiring and my entire car shorted out. Has this happened to anyone??? I am hoping the shop will pay for the repairs if in deed the issue was the install. I was told by the mechanic that at the very least my BCM is fried and needs to be replaced......
