Steering wheel controls not working after fixing airbag light!

[Surly]

I did some searching on the forum before posting this, there is a ton of info regarding steering wheel controls but it's a bit overwhelming and wasn't specific enough to my question. Any help would be appreciated!

I just had a Kenwood DDX318 head unit installed. I had to reset the windows and also had the airbag warning light go off.

I was so thrilled when I read I could fix the airbag warning light myself, I just followed the steps and it worked!

I should have known better than to think I was in the clear. Now the steering wheel controls do not work whatsoever.

Any information on how I should proceed? I'm hoping it's something I can do through the steering wheel or head unit and it won't be necessary to take it to a shop.

Anyone help would be hugely appreciated!!!!!!
