I had my 04 Crossfire parked in my rear office parking lot. Someone hit and ran the rear end. It is only going to be about 800 dollars to fix it at the auto body shop (going ahead and having the front end and hood re shot due to sand and pebble damage in Feb for another 1300.)

My main problem is after discovering the hit and run (due to hearing my alarm go off) I can not turn off the alarm with the key fob or start the car. The alarm goes off after 30-60 seconds but when I turn the key I just hear a loud ticking noise. The car does not turn over and I hear no mechanical noises such as a started.

The auto body shop is not sure why it wont crank and I want to know if this is common or if I should have it towed to my Mercedes mechanic after the shop is done reshooting it.

I have about 75k miles on it. Other than the sand and pebble chips and the now bumped rear end the car looks brand new!

Any help would be great!
