there is no such thing as aftermarket airbag - chah sultan etc is a scrapyard. They are selling used scrap as spare parts. So the airbags for any car will always be genuine (its due to liability reasons because they are actually explosives)
Your local electrician wont be able to unlock the airbag ECU, you may need to find some specialist people (showrooms know of them). OR a new air-bag ECU from Honda and then have it coded to the car (its tied with car serial no.)
