Obviously i didn't re-post what kenny said to do since he already stated it. I just thought it was funny that the same thing happen to me when i first got my g.

 

I had this problem last year, the little white plastic piece that is attached to the solenoid that looks the lid broke and was lodged in my lid. I ended up hitting the lid with my palm and the little plastic piece fell out and my lid was no longer locked. I am not recommending you do this I was just sharing my experience

until you replace it .
