Excellent point, well presented.open your glove box, put your key in the 'lock' and turn it.
oh and lol!!!
If the key switch is missing and you just have wires then your car is in a bit of a state....
Put simply you really need to get that sorted professionally as anything to do with airbags is potentially dangerous.
If you are asking questions such as this then not sure you should be getting anywhere near it... no offence...
