This is very easy and shouldn't take you more than 30 minutes all together. Drivers side is simple..you will see to plugs on the steering wheel. Remove them and unscrew the covered bolts. Air bag will come out, and you'll have to unhook a sensor.
Passenger side you will have to remove the glove box. There are 3 bolts on the bottom...either 7 or 8 mm...then you will need to remove the air duct...should understand what I mean when you get there...then there are 4 bolts holding it in...remove them and it slides out...and well remove the sensor again.
Very easy to do. Good luck!
