SRS airbag service urgent after a collision 2011 XC90

[rred]

Long story short, we hit a deer with our 2011 XC90 on a highway when traveling out of town. Got a mechanic to replace the radiator so that we were able to drive another 6 hours back home. Then it's my turn to work on the car. I was able to replace the impact bar, and was lucky enough to find the front bumper assembly from a junkyard and put it on. Got an AC condenser but still need to learn how to install it. The airbags were not triggered. But we got two warnings: "SRS airbag service urgent" and "Pass airbag off urgent". The airbag warning light is on. Is the dealer the only place to make sure the airbag system is working after a collision? How much do they usually charge for it? Thanks for any suggestions!
