I locked my keys under my hood recently, I didn't choose to call the locksmith and had to take the hinge bolts out. The plastic covers pull out of the way. You'll need at least two, ideally three people total. the air shocks wreak havoc, and you have to stay patient while getting the hood off the latch so you don't mess everything up. Just wiggle it around, make sure you have help that's not so irresponsible as to chip paint off your hood or fenders while moving it around.
Good luck.
