Hand taming my bird

Question
I have a parakeet that is about 2 years old & I finally got him (Jack) to calm down enough to put my hand in the cage. I had his wings clipped to help in training, I would go in his cage and try to catch him which was hard to do because he would try to get away from me.  I would bring him in a quiet room and have him perched on my finger.  In the room he was fine and he hopped from finger to finger and was calm.  In trying to catch him in his cage was a chore and I realized that I made him afraid of my hand again. (Stupid of me, what was I thinking...)do I still have a chance to re-train him or did I blow it and just give up or should I just get another bird for him.  I started all over again with just putting my hand in the cage and talking calmly.  I will continue to do this until he trust me again.  Is it possible to have him trust me again or once the trust is broken?
I hope its not too late.
Jack's previous owner had 2 young boys who tormented the bird so I have my work cut out for me.  When I first got Jack he would freak out if I opened the cage to change his water.  I got him calm enough to let me put my hand in the cage and he pays attention to me when I talk to him and when I sing to him he also starts to sing softly.

I hope its not too late.

Thanks for your time.

Hi, Cathy.  Thanks for posting.

How your keet will react depends on his individual personality.  Some birds are very "forgiving" and easy trust their humans again (i.e., some forget easily and some don't, depending on how tramatic an incident is to them...and each perceives this differently).  I recommend you do not try to grab your keet up from inside it's cage.  Allow him to come out on his own first or bring him out via a perch or your finger...do not grab him to bring him out (parrots normally dislike being grabbed around their bodies).  

Be aware that the inside of a bird's cage is it's safety zone, it's personal territory, it's security, etc.  Most don't like intrusions into their territory...this is why they bite or freak out (they feel cornered/trapped since they have no way to escape when their human sticks their hand/arm inside the bird's cage).
