starter problem in damaged audi s5?

so i have this broken audi s5 2010,

the buttons on the key do not work, however u can turn the ignition on, but not start the
vehicle.

the damage was not severe, it was it in the right front side, mainly under the car was
damaged, like the radiator needs to be replaced and plastic bumper, and some hoses
too.
it looks like the previous owner drove over something and it went under the car.

the coolant spilled out of the car. The computer says service due and check coolant
level.

when i apply the brake and try to start the car it makes two ticking noises, like the
engine
wont turn over, just the starter makes one tick when u push in the key and one tick
when
you release the key.

i was curious as too if this is a computer problem or not, because i know a vehicle with
coolant or without should start no matter what. yes the engine would start on fire but it
should turn over.

I will probly have a person look at the car to fix it.

but im here to see if anyone can answer this problem.

also i'd like to say that the right side air bags went off, and i do not have the emergency
key, its missing.
