SRS module reset

I have an MX5 built in late 2016. During a track day I got involved in a fender bender and popped an airbag. I replaced that immediately and also got the fender fixed. I want the airbags to work so I gave the module to a workshop that said they can do a reset.

They showed me the eeprom data before and after their change, letting me know my VIN was still in there. But when I plugged the module back and powered up the car, every light on the dash lit up.

Am I supposed to do something else? Reset a specific code in the ecu or recalibrate a sensor, possibly with a very expensive obd dongle and accompanying software (IDS/VCS)?
