Howling:Why hasn't Amy been given a TARDIS Key?

Why hasn't the Doctor given Amy her own key - did he run out or somthing? And before anyone says that he sees her as a small child and doesn't trust her with a key, he trusted her with the sonic screwdriver in The Big Bang, which says alot. MidnightCat
 * The screwdriver was different. She didn't know she had it. He hid it in her top pocket for him to get as soon as he returned to the museum. He had no intention of letting her keep it. As for the key... no idea. From what we've seen, Amy does seem to get into a lot of trouble on her own. If she was captured and the bad guys got a TARDIS key, that wouldn't be the best thing to happen. It might not be that he doesn't trust her, but that he knows what she's like. --The Thirteenth Doctor 20:14, August 10, 2010 (UTC)
 * Do we know that she doesn't have one for sure? The only occasion I can really remember to indicate that she doesn't is when he'd soniced the door shut?  Am I forgetting something?  I know we haven't seen him give her one, but I'm not sure that's definitive, since in the new series he tends to give keys to his companions. 207.171.251.183 21:45, August 10, 2010 (UTC)
