Cheers for the speedy response, unfortunately I have checked and there is no key hole on side of dash.
I believe it has been been turned off, have had no luck looking online where the lockout may be located though. Is it possible that wires may have been disturbed under the seats? Cheers

Hello! I’ve recently purchased my first car (Suzuki swift 2005 mk3) I have an issue with the airbag light just wondering if it’s possible it’s been turned off by an elderly driver for baby seat possibly? How can I go about checking this and how can I turn it off. Many thanks, Max
