dj-t

I have a 94 civic si hatch, I went to the store this morning and as I was going to get out my door wont open. Tried unlocking and opening it from the outside/inside no luck at all. Got home tried to figure out what the hell is going on and compared the passenger door latch to the driver. I can't figure what is going on, has this happen to you guys before? Any suggestion is greatly appreciated.
