Continuity mistake: When Claire and West are talking about their abilities on the beach, the close up shots of Claire show that she is wearing earrings, the camera goes to West but when it focuses on Claire again she is no longer wearing them.
Chosen answer: Hiro's powers are still quite unreliable, and a locked closet door isn't a huge obstacle. Since Hiro knows he needs to rescue Ando, it's probably safer to try and bash the door down than risk teleporting to the wrong place or time.
