I believe there is a special fuse right at the battery that automatically blows upon airbag deployment. You have to get it from the dealer.

There are numerous things that have to be replaced after a deployment, including the airbag module and it is possible that could disable starting also.

Just wanted to add, during a bag deployment the SRS module sends a signal to the engine control module to shut the fuel pump off to avoid a risk of fire. After repairs are done, the system needs to be reset using a factory or similar type of scan tool to give the okay to start

The airbag module cannot be reset after a deployment. It has to be replaced.
