To add to that, you should disconnect your battery and wait at least 90 seconds before disconnecting the airbag. Then after that, it shouldn't matter if your accidentally turn your ignition on while the airbag is disconnected. But the whole disconnecting the battery thing isn't for this reason... it's for safety reasons. That said, I still feel a little bit on the edge every time I have to unplug an airbag. The through of it going off kind of scares me. Ingres, you saw me remove your airbag before when I fitted your foglights right? Dont know if insurance would cover that if you set it off your self modding your car. I usually just put a bit of masking tape over the key barrel to remind me to much effort disconnecting battery and re tuning radio stations lol.
